摘要   考察了几种锆类化合物添加剂对硬硅钙石形貌的影响。实验结果表明:锆英石和氧化锆作为添加剂时,硬硅钙石结晶不好,纤维结合紧密,形成了密实、团聚的硬硅钙石二次粒子,此结构倾向于制备高强度绝热制品;使用氧氯化锆作为添加剂所制备的硬硅钙石结晶良好,所生成的硬硅钙石二次粒子具中空结构,此种结构易于形成超轻绝热制品。 The effect of several zirconium compounds as additives on the morphology of xonotlite crystals was examined. Results have shown that the xonotlite fibers were not well developed when zircon and zirconia were used as additives,therefore the xonotlite fibers formed dense and aggregated secondary particles through close intergrowth,Such secondary particles are usually stronger than the hollow secondary particles,therefore are readily amenable to prepare high strength thermal insulating materials. When zirconium oxychloride was used as additive,the prepared xonotlite minerals are well crystallized. The intergrowth of the xonotlite minerals formed secondary particles with hollow structure,such secondary particles are readily amenable to form super light thermal insulating materials.
