It was shown that in order to obtain glazed ceramic material with heightened heat resistance the CLTE of the ceramic material must not exceed the CLTE of the glaze by more than 1.50 – 1.55%. It was found that separation into three or four regions occurs in silica-enriched glaze as a result of segregation of glass. The segregation structure appreciably decreases at 700 and 950°C. The temperature interval of segregation is a function of the conditions of heat-treatment of the glaze.

基于有色金属废料和釉料的陶瓷材料的线性热膨胀系数及其烧成机理

结果表明，为了获得具有更高耐热性的釉面陶瓷材料，陶瓷材料的CLTE不能超过釉料的CLTE超过1.50 – 1.55％。已经发现，由于玻璃的偏析，在富含二氧化硅的釉料中分成三个或四个区域。在700和950℃下，偏析结构明显降低。隔离的温度间隔是釉料热处理条件的函数。
