英文摘要	The high strength aluminous porcelain insulator with a mineral composition of kaolinite, corundum, microcline, quartz, small amounts of albite and anatase was investigated by in situ high temperature xrd (htxrd) from 25 degrees c to 1300 degrees c the amount change and reaction of minerals contained in the porcelain insulator were presented vividly. the full process occurred in successive stages: 1) kaolinite decomposed into amorphous metakaolinite in the temperature range of 500-600 degrees c; 2) metakaolinite kept amorphous form up to,about 1000 degrees c; 3) at about 1000 degrees c, amorphous metakaolinite generated primary mullite; 4) after bout 1200 degrees c, microcline began to melt, forming an alkaline liquid phase which facilitated the growth of primary mullite into secondary mullite; 5) the alkaline liquid phase could etch beta-quartz, resulting in the reflection intensity of beta-quartz decreasing; 6) corundum was very stable in the whole heating process.
