虽然氮化硅目前是燃气轮机和其他高温工程应用的主要竞争者，但它只是氮陶瓷广泛领域的第一个，其他成员为技术开发提供了更好的前景。“Sialon”是Si-Al-O-N和相关系统中的相，并且在种类和多样性方面与矿物硅酸盐相当。它们是由（Si，Al）（O，N）4四面体的一维、二维和三维排列组成的，与硅酸盐的基本结构单元是SiO 4四面体相同。这些新的氮氧化物包括基于α和B氮化硅、氮氧化硅、氮化铝和碳化硅、锂霞石、尖晶石、黄长石和磷灰石的结构类型。人们正在研究它们的热、机械、化学和电学特性。
Although silicon nitride is at present a leading contender for gas turbines and other hightemperature engineering applications, it is only the first of a wide field of nitrogen ceramics, other members of which offer better prospects for technological exploitation. “Sialons” are phases in the Si-Al-O-N and related systems and are comparable in variety and diversity with the mineral silicates. They are built up of one-, two-, and threedimensional arrangements of (Si, Al) (O, N)4tetrahedra in the same way that the fundamental structural unit in the silicates is the SiO4tetrahedron. These new oxynitrides include structure types based uponαandΒsilicon nitrides, silicon oxynitride, aluminium nitride and silicon carbide, eucryptite, spinel, melilite and apatite. They are being explored for their thermal, mechanical, chemical and electrical properties.
