| 摘 要： | 以油页岩渣为主要原料制备了微晶玻璃,探讨了微晶玻璃组成、主晶相确定和晶核剂选择等问题.采用DTA,XRD和SEM等测试手段,分析了晶核剂和热处理制度对微晶玻璃的影响.结果表明:复合晶核剂(TiO2+P2O5)能有效促进油页岩渣玻璃晶化;最佳热处理制度为:850℃核化100 min,980℃晶化80 min.微晶玻璃的主晶相为钙铁透辉石,次晶相为钙长石;晶体呈纤维状结构并且交错分布;性能明显优于同类的瓷质砖、大理石和花岗岩等建筑装饰材料.

| Abstract: | A glass-ceramics was prepared with oil shale residue as primary material.The compositions of glass-ceramics and selection of both main crystallization and nucleating agents were discussed.The effects of nucleating agents and heat treatment procedure on glass-ceramics were analyzed by means of DTA,XRD and SEM.The results showed that the composite nucleating agent TiO2+P2O5 can efficiently step up the crystallization of such a glass-ceramics.The optimal heat treatment procedure was found as nucleating at 850 ... |
