浸渍Ca3(PO4) 2 与AlPO4混合饱和溶液 ,有利于SiC窑具材料晶相结构的转化与性能的优化 ,使SiC结构由低温稳定型向高温稳定型转化 ,α -SiC含量随着浸渍次数的增加而增加 ,浸渍 4次α -SiC含量最高 .材料性能随浸渍次数增加而优化 ,浸渍 4次的抗折强度、热震后抗折强度保持率和体积密度最高 ,显气孔率与吸水率最低 ,浸渍混合饱和溶液效果优于浸渍Ca3(PO4) 2 饱和溶液 .
Dipping SiC kiln furniture into the saturated solution of Ca 3(PO 4) 2 and AlPO 4 is beneficial to its crystalline structure change and its properties. It helped the SiC structure change from low-temperature stable type to high-temperature stable type. The percentage of α-type SiC increased with the dipping times and it reached the highest after 4 times .The properties of SiC improved with the dipping times. The bending strength, the keeping rate of bending strength after heat shock and bulk density were the highest, the apparent porosity and absorrption were the lowest after dipping for 4 times. The effect of dipping into the mixing saturated solution is better than that of dipping into Ca 3(PO 4) 2 saturated solution.
