Description
技术领域
本发明属于材料领域，具体涉及耐热震基底材料及其用作太阳能热发电吸热材料的用途。
背景技术
太阳能作为一种绿色能源对环境没有任何无污染性，而且它的来源简单，可以说是在人类的生存年限内其是取之不尽用之不竭的。太阳能不仅是一次性能源，还是清洁能源，它资源丰富、普遍存在、无需运输、还可免费使用、最重要的是对环境没有任何污染。太阳能电池也因太阳能的特殊性具有许多其他发电方式所不具备的优点：不受地域限制、不消耗燃料、规模可大可小、灵活性大、无污染、无噪音、安全可靠、建设周期短、维护简单、最具有大规模应用的可能性。所以很多专家把太阳能能源作为可替代的能源去开发，希望太阳能够造福于人类。现如今所使用的太阳能有很大一部分是由太阳电池转换得来的。因为太阳能电池对光有感应，能够把照射在其表面的光能转换为电能。目前，在有关专家的努力下，太阳能电池己经走向了商业化和产业化。
太阳能发电种类很多，较为成熟的有太阳能光伏发电和太阳能热发电。在众多的太阳能利用技术中，太阳能热发电技术被誉为最有前景，最有可能大规模利用太阳能的技术。太阳能热发电是利用聚光器聚集太阳能，经吸收器吸收后，转化成热能，产生高温蒸汽或气体进入汽轮机发电机组或燃气轮机发电机组产生电能。按聚光形式不同，太阳能热发电可分为塔式太阳能热发电、槽式太阳能热发电和碟式太阳能热发电。塔式太阳能热发电系统由于聚光比高、热力循环温度高、热损耗小、系统简单且效率高的特点得到世界各国的重视，是目前各国都在大力研究的先进的大规模太阳能热发电技术。而作为塔式太阳能热发电核心的空气吸热器，其中的高温吸热体材料担负着接收太阳聚光能量，以及吸热、换热的重要作用，影响着整个热发电系统的稳定性及效率的高低。
研发一种耐热震的基底材料迫在眉睫。

实施例8：效果实施例
抗热震性反映的是材料承受温度的急剧变化而不致破坏的能力，它是决定材料使用寿命的最关键的参数之一。实验步骤如下：将样品放入高温炉，以5℃/min的升温速率升至1100℃，保温60min后取出放在室温空气中自然冷却，将实施例1～7配方试样置于高温电阻炉内，热震至60次。分别在第10次、20次、30次、40次、50次以及60次抗热震后取出测试抗折强度，计算强度损失率并描述圆片样品的外观，结果如下表所示。
采用日本真空理工株式会社激光热常数测试仪TC-7000H测试实施例1～7配方试样的导热系数进行了测试，结果见下表。
抗氧化测试采用不连续称重法测试，将试样放入空气流动状态良好的箱式硅钥帮电阻炉中，1300℃下保温3h。然后将试样从炉内取出，在空气中缓慢冷却后，用电子天平称量试样的质量，记录前后变化量，以变化量比试样未氧化前的质量计算抗氧化性，结果见下表。
| 出现裂纹的热震次数 | 抗折强度/MPa | 导热系数W/(m·k) | 抗氧化性/％ | |
| 实施例1 | 60次无裂纹 | 110 | 33.5 | 0.35 |
| 实施例4 | 60次无裂纹 | 103 | 31.8 | 0.38 |
| 实施例5 | 60次无裂纹 | 105 | 32.3 | 0.39 |
| 实施例6 | 30次 | 55 | 15.4 | 1.45 |
| 实施例7 | 30次 | 53 | 15.1 | 1.49 |
实施例2、3的测试结果与实施例4、5基本一致。
