摘要
以石灰石为原料，采用湿化学方法添加ＺｒＯ２，气相扩散方法掺入Ｃｒ２Ｏ３，水蒸汽消化轻烧氧化钙和消除烧成过程中产生的裂纹等技术，获得了ＣａＯ含量＞９８％，体积密度为３．２５ｇ／ｃｍ３，抗压强度＞１５０ＭＰａ，大气存放６０天水化增重率＜１％的抗水化高纯氧化钙材料。
Using calcite as raw material,adding ZrO 2 by wet chemical method,dropping Cr 2O 3 by vapor diffusion method,hydrating light calcined calciun oxide by aqueous vapor and eliminating the crack formed during sintering,the high purity hydration resistance calcium oxide refractory was developed with CaO content of>98%,bulk density of 3.25g/cm 3, cold compressive strength of>150MPa and increase in weight of<1% due to hydration in atmosphere for 60 days.
