Study on low thermal expansion petalite-phosphate composite ceramic
low thermal expansion petalite-phosphate ceramic material was prepared by using natural mineral petalite，Hualin kaolin,Guizhou kaoJin,Guangxi talc．Shanxi zimujJe clay and some artificially synthesized NaZr2(P04)3 as raw materials by ordinary ceramic preparation method．The effect of synthesizing temperature on the synthesis of phosphate was studied．The
result indicates that the powder synthesized at 1450℃ for 1 h has the minimum thermaI expansion coefficient。When the sodium hydrogen zirconium phosphate additive amount is 5 wt％，the petalite-phosphate composite ceramic has low thermal expansion coefficient at 1250°C with 30 min soaking time．
