摘　　要：采用酸沥滤方法,对钙镁硅系陶瓷纤维进行了表面处理,测试结果表明,沥滤处理降低了纤维中碱土金属CaO和MgO的含量、提高了SiO2的含量;采用适中的硫酸溶液浓度(1～3mol/L),可以在保持纤维/纤维制品性能变化不大的情况下,提高纤维的晶化温度,明显抑制纤维的晶化。The calcium-magnesium-silicate ceramic fiber was treated with acid leaching method. The testing results show that contents of CaO and MgO decreased and that of SiO2 increased after leaching treatments. With the concentration of sulfuric acid solution between 1-3 mol/L, the crystallization temperature was elevated and the crystallization was inhibited maintaining the properties of fibers invariantly.
