摘　　要：以滑石、高岭土和化学试剂合成了两种析晶促进剂,加入到废玻璃粉末中烧结制备成透辉石-钠长石玻璃陶瓷。研究了析晶促进剂的组成和加入量对玻璃陶瓷析晶和性能的影响。结果表明,在烧结过程中,析晶促进剂和玻璃发生反应,析出透辉石和钠长石。析晶促进剂的组成和加入量对反应析晶有一定影响,随析晶促进剂加入量的增加,玻璃陶瓷密度和强度先增后降,存在一最佳加入量,这时烧结的玻璃陶瓷有较高的密度和强度。Two kinds of crystallization promoters were synthesized using kaolin day, talc and chemical reagents. Diopside-albite glass-ceramics were prepared by adding the promoters to the waste glass powder and then sintering. The effect of the promoter components and additions on the crystallizing behaviors and properties of glass-ceramics was investigated. The results showed that diopside and albite crystals developed by a reaction between the promoter and glass during sintering. The promoter components and additions had some effects on the reactive crystallization. The density and strength of glass-ceramics initially increased and then decreased with increasing promoter additions. There is an optimal addition of the promoter, the glass-ceramic with which had higher value of density and better strength.
