摘要
本文通过组成设计,以Si、Al、Y2O3为原料,Si3N4为稀释剂,利用自蔓延高温合成法(SHS)制备了Y-α/β-Sialon粉末;并利用XRD、化学分析法分别研究了α-Sialon简称α′)、β-Sialon简称β′)相组成和游离硅含量;且详细讨论了氮气压力、稀释剂含量对生成物Y-α/β-Sialon中的α′、β′相及残余硅含量的影响.
Polyphase Y-α/β-Sialon powders were prepared by SHS method, with St, Al, Y2O3 and Si3N4as raw materials under high nitrogen pressure. The effects of nitrogen pressure and the amount ofdiluent on α', β' phase compositions and the amount of free Si were studied in detail.
