Description

超导电材料及其制备方法 技术领域  Superconducting material and preparation method thereof
本发明涉及超导电材料及其制备方法, 尤其是临界温度 Te高于常温的超 导电材料及其制备方法。 背景技术 The invention relates to a superconducting material and a preparation method thereof, in particular to a superconducting material having a critical temperature T e higher than a normal temperature and a preparation method thereof. Background technique
1、 超导电材料现有的技术状况: 提高超导体的临界温度 Tc, 即研制高临 界温度 Te的超导电材料, 一直是超导材料研究的核心课题之一。 直到 1986 年 A. Muller和 J. G. Bednorz俩人的 "钡镧铜氧系统中可能的高 Tc超导电 性" 划时代的发明, 才使超导材料 Te突破了超低温壁垒, 达到 35K。 但是第 一直到目前为止, 超导材料 Tc的最高记录仍保持在 164K。 此 Te值的材料为 Hg— Ba— Ca— Cu—O铜系氧化物材料, 由美国科学家朱经武于 1994年研制 发明。 2001年 3月美国和日本科学家又发明了 MgB2材料的超导电材料, Tc 为 39K。 2001年有报道用空穴注入法将有机超导的 Tc提高到 117K。 2001年 3月美国贝尔实验室制造出结构有规则的 Ρ3ΗΤ有机薄膜,并用场效座晶体管 往薄膜注入电荷, 在 2.35Κ薄膜出现超导电性。 2000年 12月美国科学家把纯 的 C6。材料的 Te提高到 52K。 而常温 Te超导电材料至今仍没能突破。 第二铜 系氧化物超导材料由于其陶瓷类的脆性缺陷, 要制出工程上适用的长导线线 材, 技术上至今仍很困难。 1. Existing technical status of superconducting materials: Increasing the critical temperature T c of superconductors, that is, developing superconducting materials with high critical temperature T e , has always been one of the core topics in the research of superconducting materials. Until 1986, A. Muller and JG Bednorz's epoch-making invention of "high T c superconductivity in the beryllium copper oxygen system" made the superconducting material T e break through the ultra-low temperature barrier to 35K. But up to now, the highest record of superconducting material T c has remained at 164K. The material of this T e value is Hg—Ba—Ca—Cu—O copper-based oxide material, which was developed and developed by American scientist Zhu Jingwu in 1994. In March 2001, American and Japanese scientists invented a superconducting material of MgB 2 material with a T c of 39K. In 2001, the hole injection method was used to increase the T c of organic superconductors to 117K. In March 2001, Bell Labs of the United States produced a regular Ρ3ΗΤ organic film, and used a field effect transistor to inject charge into the film, and superconductivity appeared in the 2.35 Κ film. In December 2000, American scientists put pure C 6 . The T e of the material is increased to 52K. The room temperature T e superconducting material has not yet broken through. The second copper-based oxide superconducting material is technically still difficult to produce due to the brittleness defects of ceramics.
2、 直至目前, 与本发明技术特征最接近的现有的超导材料, 为日本物质 材料研究所发明的钴氧化物 "粘水" 材料。 干燥状态下钴氧化物不具备超导 电性, 在负 268 °C时将钴氧化物层注入水分子, 其磁化率和电阻急剧下降, 使 之成为超导物质。 钴氧化 "粘水" 材料, 显然使用了水分子的极化共价键 H+ 均比较低, 无法实现常温临界温度 Tc。 发明内容 2. Up to now, the conventional superconducting material closest to the technical feature of the present invention is a cobalt oxide "sticky" material invented by the Japanese Institute of Materials Research. Cobalt oxide does not have superconductivity in dry state Electrically, when a cobalt oxide layer is injected into water molecules at a negative temperature of 268 °C, its magnetic susceptibility and electrical resistance drop sharply, making it a superconducting substance. Cobalt oxidized "sticky" materials, it is clear that the polarization covalent bond H+ of water molecules is relatively low, and the normal temperature critical temperature T c cannot be achieved.

制备实验说明  Preparation experiment description
①通过对比观察,实验过程中试剂总析出水量明显多于等量的 BaCl2 ·2Η20 单独加热去结晶水时的总析出水量, 表明在实验过程中, 当 K0H与 BaCl2发生 反应生成 KC1和 Ba (0H) 2后, 高温加热时, 部分 Ba (0H) 2也参与了水析出, 生 成 BaO成份。 ②根据化学反应及实验观察, 确定, 此制备材料的组成由 CuHz、 KCK BaCl2、 BaO, Ba (OH) 2所示的化学成分组成。 ③用 NaOH代替上述实验中 的 K0H做此实验, 二者实验得到的完全抗磁性效果基本相同。 ④用 Cu粉代替 此实验中的 CuHz做此实验, 则实验始终无完全抗磁性显示, 其原因是, 在强 碱环境中、 同时又有水(主要为 BaCl2 · 2H20的结晶水)和氧存在的情况下, 加 热时, Cu极易被氧化造成的。 氧化后, Cu则丧失对 H+p的吸附作用。 1 By comparison, the total amount of water in the reagents during the experiment was significantly higher than that of the equivalent amount of BaCl 2 ·2Η 2 0 when the decrystallization water was heated alone, indicating that K0H reacted with BaCl 2 to form KC1 during the experiment. After Ba (0H) 2 , when Ba is heated at a high temperature, part of Ba (0H) 2 is also involved in water precipitation to form BaO components. 2 According to the chemical reaction and experimental observation, it was confirmed that the composition of the preparation material was composed of chemical components represented by CuH z , KCK BaCl 2 , BaO, Ba (OH) 2 . 3 Using NaOH instead of K0H in the above experiment to do this experiment, the complete diamagnetic effect obtained by the two experiments is basically the same. 4 Using Cu powder instead of CuH z in this experiment, the experiment has no complete diamagnetic display. The reason is that in the strong alkali environment, there is water (mainly BaCl 2 · 2H 2 0 crystal water). In the presence of oxygen, Cu is easily oxidized when heated. After oxidation, Cu loses its adsorption to H +p .

把实施例 7组分中的(¾ 用 Cu粉代替, 进行制备实猃, 制备材料的完全 抗磁性效果与实施例 7基本相同。 由此说明, 实施例 6又用 Cu粉代替 CuHz 制备时出现的 Cu被氧化, 是由于 K0H并水(BaCl2 · 2H20的结晶水)的存在造 成的, 同时也说明 CuHz中的 H有保护 Cu不被腐蚀的作用。 The complete diamagnetic effect of the prepared material was substantially the same as that of Example 7 except that (3⁄4) of the component of Example 7 was replaced with Cu powder, and it was explained that Example 6 was replaced with Cu powder instead of CuH z . The appearance of Cu is oxidized due to the presence of K0H and water (crystal water of BaCl 2 · 2H 2 0), and also indicates that H in CuH z has a function of protecting Cu from corrosion.

测量方法: 材料经高温制备, 停止加热时, 随即在热状态下将制备材料 分别靠近静止磁针两端的侧面, 测量磁针是否被排斥、 排斥斥幅及排斥与温 度和时间的关系。 磁针的磁场强度 H=129高斯。 测量时排出了环境因素并否 定了材料携磁、 携电流等因素对磁针的作用。 由测量认定对磁针的排斥是材 料本身的完全抗磁引起的, 也即材料的超导电性引起的。  Measurement method: When the material is prepared at high temperature and the heating is stopped, the prepared materials are placed close to the sides of the stationary magnetic needles in a hot state, and the relationship between the magnetic needles being rejected, the rejection of the repulsion and the repulsion and the temperature and time are measured. The magnetic field strength of the magnetic needle is H=129 Gauss. Environmental factors were removed during the measurement and the effects of magnetic loading and current carrying on the magnetic needle were rejected. It is determined by measurement that the repulsion of the magnetic needle is caused by the complete diamagnetism of the material itself, that is, the superconductivity of the material.

说明一、 完全抗磁性缺陷及改进方案  Description 1. Complete diamagnetic defects and improvement schemes
以上实施例是为实施本发明做的制备实验,制备实验解决了 300 °C下的完 全抗磁并超导电问题, 并提供了制备这种材料的方法。 从表 1 所列数据看, 以上实施例中: 第一完全抗磁的时间不是非常持久; 第二完全抗磁性存在下 限温度即室温。 其原因是: 实施例中的 CuHJ々 H含量不足(z为 0. 1 ) , 在高 温下分解成 Cu和 H; 制备工艺没有实现绝对的密闭, 引起有效成分的 H损失 造成的。 这种情况下, 制备材料均存在的 Cu (或 H ) — H+p价态不平衡关系, 则主要表现为 Cu— H+p价态不平衡关系。 当温度低于下限温度时, H+p与 Cu的 热趋近或者称 H+p与 Cu的共有化热吸附在短时间内会逐渐消失(参考: ① Cu 脱 H作用的温度条件 ·有机化学实验, ②重复加热, 制备材料又恢复完全抗 磁性) , 这将导致 Cu— H+p价态不平衡体系被破坏。 破坏后, H+p相对于 Cu则 变成独立的正电中心, 而失去空穴导电性、 并不再存在电子与空穴运动地相 互关联, 使材料失去超导电性, 同时完全抗磁性也随之消失。 因此根本原因 是 CuHz试剂的 H损失造成的。 The above examples are preparation experiments for carrying out the invention. The preparation experiments solve the problem of complete diamagnetic and superconductivity at 300 ° C and provide a method for preparing such materials. From the data listed in Table 1, in the above examples: the time of the first complete diamagnetic is not very long; the second complete diamagnet has a lower limit temperature, that is, room temperature. The reason is as follows: The content of CuHJ々H in the examples is insufficient (z is 0.1), and is decomposed into Cu and H at a high temperature; the preparation process does not achieve absolute sealing, which causes the loss of H of the active ingredient. In this case, the unequal relationship of Cu (or H)-H +p valence in the prepared materials is mainly represented by the unbalanced relationship of Cu-H +p valence states. When the temperature is lower than the lower limit temperature, the heat of H +p and Cu approaches or the heat of adsorption of H +p and Cu will disappear gradually in a short time (Reference: 1 Temperature conditions of Cu de-H action · Organic chemistry In the experiment, 2 repeated heating, the material was prepared to restore complete diamagnetism), which would cause the Cu-H +p valence unbalanced system to be destroyed. After the destruction, H +p becomes an independent positive electric center with respect to Cu, and loses hole conductivity, and there is no longer any interaction between electrons and holes, which causes the material to lose superconductivity and is completely diamagnetic. It disappears. Therefore, the root cause is the loss of H of the CuH z reagent.
因此可以对实施例中的技术方案进行改进:第一完善密闭工艺,保证 CuHz 分解反应的可逆; 第二增大 CuHz中的 z达到 0. 4-0. 7。从而实现 H— H+P价态不 平衡关系 (此关系不受温度影响也与时间无关) , 即能消除上述的两个缺陷。 为了进一步提高制备材料中所含金属氢化物的热稳定性, 可用 CuM5Pd。.55Hz代 替 CuHz, 进行材料制备, 其中的 Pd (钯)对氢有良好的吸附性。 说明二、 制备实验的密闭条件 A加热时间 Thus embodiments may be made to improve the technical solution: a first confined sound process to ensure that the reversible decomposition reaction CuH z; a second increase in the z-z CuH reaches 0. 4-07. Thus, the H-H + P valence imbalance relationship (this relationship is not affected by temperature and time-independent) is achieved, that is, the above two defects can be eliminated. In order to further improve the thermal stability of the metal hydride contained in the preparation material, Cu M5 Pd can be used. 55 Hz instead of CuH z , material preparation, in which Pd (palladium) has good adsorption to hydrogen. Description 2. Sealing conditions for preparation experiments A heating time
由于试剂 CuHz 、 Zn (0H) Cl及 Sn (0H) Cl 的热稳定性差, 高温(400°C)易 分解,'并具有可逆反应 (密闭情况下):  Due to the poor thermal stability of the reagents CuHz, Zn(0H)Cl and Sn(0H)Cl, the high temperature (400 °C) is easily decomposed, and has a reversible reaction (in the case of airtightness):
CuH^=±Cu + [H]  CuH^=±Cu + [H]
Zn (OH) Cl^=^ZnO + HCl  Zn (OH) Cl^=^ZnO + HCl
试剂 Ba (OH) 2及 Ca (OH) 2 , 55(TC时开始分解失 H20 (单独、 敞口加热情 况下) , 并具有可逆反应 (密闭情况下)':  Reagents Ba (OH) 2 and Ca (OH) 2 , 55 (when TC begins to decompose and lose H20 (individual, open heat), and has a reversible reaction (in the case of airtightness)':

此处, Zn(OH)Cl为碱式氯牝锌。 因此, 必须保证制备时的密闭条件。 在 保证密闭条件下, 延长加热时间, 则能够使成粉的扩散及内部组织结构更均 匀, 从而获得更好的完全抗磁 效果。 麥考现有的铜系氧化物超导材料的制 备, 及本发明材料的主要成分是氯化物以及根据以上的制备实驗, 本 明材 料的制备在保证绝对密闭、 隔绝空气条件下, 力 时间应延长为 4-5 小时。 由于条件限制, 实施例的制备实验 ^舞保证上述妁工艺条件, 延长加 ^日 间, 实验过程中则由于出现分解反应, ; t 或管; ¾裂, 失去有效成分, 使已检测 到的完全抗磁性消失, 所以本发明 施例实验的力 时间是 2H5分钟, 由 于实-验加热时间短, 内部成份(尤其是 Cu ) i圹 不均匀  Here, Zn(OH)Cl is basic chloranil. Therefore, it is necessary to ensure the sealing conditions at the time of preparation. When the heating time is extended under the condition of ensuring the sealing, the diffusion of the powder and the internal structure are more uniform, so that a better complete diamagnetic effect can be obtained. The preparation of the existing copper-based oxide superconducting material of McCaw, and the main component of the material of the present invention is chloride and according to the above preparation experiment, the preparation of the material is guaranteed to be absolutely sealed and insulated under air conditions. Extended for 4-5 hours. Due to the limitation of the conditions, the preparation experiment of the example ensures that the above-mentioned enthalpy process conditions are extended, and during the experiment, the decomposition reaction occurs due to the decomposition reaction, t or tube; 3⁄4 crack, the active ingredient is lost, and the detected completeness is completely detected. The diamagnetism disappears, so the force time of the experiment of the present invention is 2H5 minutes, and the internal component (especially Cu) i圹 is uneven due to the short heating time of the actual test.
