Abstract
The composition of the super conductance material comprises Cu, K( or Na), Ba, Cl, O or OH and its composition. The super conductance material is made by evenly triturating CuH2, KCl( or NaCL),BaCl2, metal oxide, metal compound comprising OH, or other metal chlorides, and compressing them to isolate air, and heating them in high temperature. The super conductance material shows the ceiling temperature appearing at entirely antimagnetic and the possible super conductance critical temperature Tc is at 509k, 529k and 573k respectively.
Description
One, technical field
Critical temperature T
cThe superconductive material that is higher than normal temperature
Two, background technology
1, the existing technology status of superconductive material: the critical temperature T that improves superconductor
c, development high-critical temperature T
cSuperconductive material, be one of core topic of superconductor research always." possible high T in the barium lanthanum copper oxygen system up to nineteen sixty-eight A.Muller and J.G.Bednorz
cSuperconductivity " epoch-making invention, just make superconductor T
cBreak through the ultralow temperature barrier, reached 35K.According to literature search: 1. up at present, superconductor T
cTidemark still remain on 164K.This T
cThe value material is an oxide material for Hg-Ba-Ca-Cu-O copper, is developed in 1994 by [U.S.] Zhu Jingwu.2001.03[America and Japan] scientist invented MgB again
2Material, T
cBe 39K.Calendar year 2001 has report to inject (material is not quite clear) T with organic superconductor with the hole
cBring up to 117K.2001.03[beautiful] Bell Laboratory produces the well-regulated P3HT organic film of structure, and field-effect transistors occurs superconductivity toward the film iunjected charge at the 2.35K film.2000.12[beautiful] scientist is pure C
60The T of material
cBring up to 52K.And normal temperature T
cSuperconductive material still fails to break through so far.2. the copper system oxide superconductors will be made the long lead wire rod that is suitable on the engineering owing to the fragility defective of its ceramic-like, and is technical still very difficult so far.
2, superconduction mechanism theory background: since the century, famous superconduction mechanism theory is no less than 13 kinds so far, but the high-temperature superconductor mechanism problem is still the unsolved riddle that theoretical circles are generally acknowledged at present.On the basis of using for reference forefathers' research, I finish " the δ field of force and superconduct one superconductivity mechanism are newly discussed " paper in 2000.09 writings, this article 2001.02.03 does issue first by " global Chinese original works net under the banyan ", and 2003.08 finish contracting of this article again changes original text " the δ field of force and superconductivity " (this original text is waited to contribute).Paper has proposed new physical model and has satisfied two necessary and sufficient conditions of superconductivity.This provides useful theory to help for own to superconductor ground experimental exploring.According to the understanding of paper to superconduction mechanism, the exploration of normal temperature superconductor should be placed hope on metal ion type compound-material, and copper system oxide superconductors issue in 1986 and that carry out development was thus furtherd investigate its T through nearly 17 years (by 2003)
cValue can not increase again.Tentatively test based on this thinking and I, determine I am transferred to metal-metal chloride material to the exploration emphasis of normal temperature superconductor.Before and after year June in July, 2004 to 2005, done a large amount of experiments.
3, so far, with the immediate existing superconductor of the technology of the present invention feature, be cobalt/cobalt oxide " sticking water " material (Japanese material research institute, 2003.03.08 www.xinhuanet.com report, my 2005.03 retrievals).Cobalt/cobalt oxide does not possess superconductivity under the drying regime, in the time of negative 268 ℃ the cobalt/cobalt oxide layer is injected hydrone, and its magnetic susceptibility and resistance sharply descend, and make it to become superconducting material.Cobalt oxidation " sticking water " material has obviously used the polarization covalent bond H of hydrone
+Ion, the H that this technical characterictic and the present invention use
+ PIon characteristic is similar.The present invention is different with it to be characterised in that, the present invention has used Zn (OH) Cl or Sn (OH) Cl or Ba (OH)
2Or Ca (OH)
2In H
+ PThe valence electron of ion and simple substance Cu (or alloy CuH
zValence electron), and metal chloride and metal oxide, thus obtain complete diamagnetic state under the 573K, its T
cValue is far above the T of cobalt/cobalt oxide " sticking water " material
cValue (5K, negative 268 ℃).Another important difference is that the present invention does not belong to pure superconductive compound materials, but simple substance (or hydrogen alloy) superconductive compound materials that never occurs up to now.From H
+ PMeaning on say that cobalt/cobalt oxide " sticking water " material provides experiment support for validity of the present invention.
Three, summary of the invention
The objective of the invention is to, a kind of CuH is provided

1, preparation experiment explanation
Illustrate one, perfect diamganetism defective and improvement project
Above embodiment is the preparation experiment of doing for enforcement the present invention, the complete diamagnetic and possible superconduct problem under preparation experiment has solved 300 ℃, and the method for preparing this material is provided.From the listed data of table 1, there are two defectives in above preparation experiment: the 1. diamagnetic fully time is not lasting; 2. there is lower limit temperature (room temperature) in perfect diamganetism.According to experiment and experimental analysis, cause the reason of these two defectives to be: self-control reagent CuH
zH contain quantity not sufficient (≤0.1), resolve into Cu and H under the high temperature; Preparation technology fails to guarantee the process conditions of absolute airtight, secluding air heating and cooling, causes that the H loss of active ingredient causes.These are confirmed by a large amount of experiments.In this case, prepare Cu (or H)-H that material all exists
+ PThe uneven relation of valence state (seeing Instructions Page 3) then mainly shows as Cu-H
+ PThe uneven relation of valence state.When temperature is lower than lower limit temperature, H
+ PHot convergence or title H with Cu
+ PBe adsorbed in the short time can fade away (reference: 1. Cu takes off the temperature conditions Experiment of Organic Chemistry of H effect, 2. repeats heating, and the preparation material recovers perfect diamganetism again) with the total heat-transmission of Cu, this will cause Cu-H
+ PThe uneven system of valence state is destroyed.After the destruction, H
+ PThen become independently positive center with respect to Cu, and lose hole conductivity, also interrelated with no longer having the motion of electronics and hole, make material lose superconductivity, perfect diamganetism also disappears thereupon simultaneously.Analyze thus, the preparation material exists above-mentioned defective to be inevitable, and its basic reason is CuH
zThe H loss of reagent causes.Improvement project: 1. improve airtight technology, guarantee CuH
zDecomposition reaction reversible; 2. increase CuH
zIn z reach 0.4~0.7.Thereby realize H-H
+ PThe uneven relation of valence state (this concerns that temperature influence is not irrelevant with the time yet) can be eliminated two above-mentioned defectives.In order further to improve the thermal stability of institute's containing metal Hization thing in the preparation material, available Cu
0.45Pd
0.55H
zReplaced C uH
z, carrying out material preparation, Pd wherein (palladium) has good adsorption to H.
Illustrate two, the airtight condition and the heating time of preparation experiment
Because reagent C uH
z, Zn (OH) Cl and Sn (OH) Cl poor heat stability, high temperature (400 ℃) easily decomposes, and has reversible reaction (under the airtight situation):
Reagent Ba (OH)
