将废玻璃粉与钙铝黄长石、氟化钙混合,使用反应析晶烧结法制备出主晶相为枪晶石的玻璃陶瓷.研究了钙铝黄长石和氟化钙含量、烧结温度对玻璃陶瓷晶相、相对密度、烧结率、吸水率及力学性能的影响.结果表明,加入15％(质量分数,下同)钙铝黄长石和6％氟化钙时,玻璃陶瓷中析出的主晶相为枪晶石.提高钙铝黄长石或氟化钙含量有硅灰石析出.在850℃和900℃烧结后,玻璃陶瓷的相对密度和烧结率都随钙铝黄长石或氟化钙含量的升高而降低,其中,提高氟化钙含量比提高钙铝黄长石含量对烧结阻碍作用更大;吸水率随钙铝黄长石或氟化钙含量的升高而升高;玻璃陶瓷的强度随钙铝黄长石或氟化钙含量提高而降低,随温度升高而变大.和850℃相比,900℃烧结后,枪晶石玻璃陶瓷的强度最大可提高51％.
