摘　　要：采用工业石灰和石英粉,选用氯化钙、硝酸锶、氧氯化锆为添加剂,研究添加剂对合成纳米直径硬硅钙石纤维的影响,结果表明,几种添加剂均对生成硬硅钙石纤维有一定的帮助,加入适量的氧氯化锆添加剂,可以制备出纳米直径的硬硅钙石纤维,氧氯化锆的添加量为Zr4+/(Ca2++Si4+)=0.02(摩尔比)时,可获得结晶良好、直径为70～100 nm的硬硅钙石纤维。The effect of additives on synthesis of xonotlite fiber with nano diameter is studied using industrial lime and quartz powder, selecting calcium chloride, strontium nitrate,zirconium oxyehlofide as additives. The result shows that these additives are certainly helpful to the synthesis of xonotlite fiber, adding appropriate zirconium oxyehloride as additive, xonoflite fiber with nano diameter can be prepared. The amount of zirconium oxychloride is Zr^4＋ / （Ca^2＋＋Si^4＋）-0.02（molar ratio）, the xonotlite fiber have good co, stallization, with 70-100nm diametem.
