”syalon“是鲁卡斯公司的商品名,它描述一系列含Si、Y、Al、O和N的可烧结陶瓷。它们是以β-Si_3N_4的结晶结构为基础,其主相是β′固溶体Si_(6-x)Al_xO_xN_(8-x)的衍生物,其中x通常<1。把元索Y,Al和O合金化的主要作用在于控制第二相的组成,原子排列和体积分数。Syalon材料可制成各种形状制品。Syalon材料在工程上的应用如下: 1.金属切削: Syalon材料的第一个主要应用是金属切削,鲁卡 “Syalon” is the trade name of Lucas, which describes a series of sinterable ceramics containing Si, Y, Al, O and N. They are based on the crystal structure of β-Si_3N_4, whose main phase is a derivative of the β ’solid solution Si_ (6-x) Al_xO_xN_ (8-x), where x is usually <1. The primary effect of alloying the elements Y, Al and O lies in controlling the composition, atomic arrangement and volume fraction of the second phase. Syalon materials can be made into a variety of shapes. Syalon materials in engineering applications are as follows: 1. Metal cutting: Syalon material is the first major application of metal cutting, Luka
