研究了SiO2和类质同晶化合物AlPO4、GeO2和LiAlSiO4的石英结构的显微硬度随温度的变化关系。特别注意的是高-低反转的影响，这已被发现是异常的相对于其他多晶型转换的行为。高石英结构被发现比低石英更硬和更脆，尽管它们的结构非常相似。
The temperature dependence of the microhardness of the quartz structures of both SiO2 and the isomorphous compounds AlPO4, GeO2, and LiAlSiO4 has been examined. Particular attention has been given to the effects of the high-low inversion, which has been found to be anomalous relative to the behavior of other polymorphic transformations. The high quartz structure has been found to be much harder and more brittle than low quartz, despite their very close structural similarity.
