摘　　要：采用传统的固相法合成白榴石晶体,研究了化工原料、钾长石及制备方式对合成白榴石晶体的影响,以及白榴石含量对玻璃陶瓷强度的影响。结果显示:采用化工原料合成并压制成型所得到的白榴石晶体最好;当白榴石含量不超过50%时,增加白榴石含量可明显提高玻璃陶瓷的强度;玻璃陶瓷的显微结构表明添加的白榴石可均匀分布于玻璃陶瓷的玻璃相中。In this study, traditional solid phase synthetic method for synthesizing leucite is used. The influences of K-feldspar, chemical materials as main raw materials, prepared ways and the content of leucite on compressive strength of dental glass porcelain are investigated. The chemical materials via pressing molding is the best. When results show that the leucite crystallization prepared by the the content of leucite is less than 50 percent, with the increase of leucite content, the compressive strength of the glass porcelain considerably increases. Microstructure observation on the glass porcelain shows that the added leucite is uniformity distributed in the glass porcelain.
