1、绪言 随着高温工程学的发展。用简单的办法取得超高温并能精密控制的电阻炉势必有所增加。尤其是培育高熔点材料的单晶体、研究高温状态下的物理性能、进行高温热处理等都要求超过以往电阻发热材料的安全使用温度。 以导电的、高熔点的铬酸镧(LaCrO_3或叫镧铬复合氧化物)为主要成分制造的加热元件。在日本的商品名叫刻拉麦克司加热元件。暂简称为刻拉元件。把它用在氧化性气氛1500℃以上的超高温电阻炉中发挥了良好的作用。
1, Introduction With the development of high temperature engineering. A simple way to obtain ultra-high temperature and precision control of the resistance furnace is bound to have increased. In particular, it is required to cultivate a single crystal of a high-melting point material, to study the physical properties under a high-temperature condition, to perform a high-temperature heat treatment, and the like, all of which require more than the safe use temperature of a conventional resistance heating material. A conductive, high melting point of lanthanum chromite (LaCrO_3 or lanthanum chromium composite oxide) as the main component of the heating element. In Japan, the product name is Kelamaike heating element. Temporarily abbreviated as Kela components. It is used in an oxidizing atmosphere 1500 ℃ above the ultra-high temperature resistance furnace played a good role.
