【摘要】 利用湖北钟祥累托石作为合成堇青石的主要原料 ,主要研究了烧成温度对合成堇青石性能的影响。试验表明 :用累托石合成堇青石其合成温度低 ,最佳合成温度为 12 70℃～ 12 90℃ ,合成温度范围宽 ,合成堇青石的膨胀系数为 2 .65× 10 - 6 /℃ (RT～ 10 0 0℃ ) ,体积密度2 .0g/cm3。说明用累托石合成堇青石具有开发和应用价值更多还原

【Abstract】 In this paper,rectorites were used as the main raw material for synthesis of cordierite,the influences of sintered temperature on the properties of cordierite were studied.The results indicate the sintered temperature is lower and the best is 1270℃～1290℃,the CET(RT～1000℃)of cordierite is 2.65×10 -6 /℃,density is 2.0g/cm 3。更多还原
