The effect of quartz addition was investigated on the sintering processes of powder compacts made from frit and glass powder with quartz powder. The results obtained are summarized as follows. 1) The quartz powder gave some effects on the shrinkage curves and the firing temperature range of frit and glass powder. Pyrex glass powder was more effective on the firing temperature range of the powder compacts with quartz addition comparing with other frits and glass powders. 2) The produced crystal during heat treatment of the powder compacts made from pyrex glass powder with quartz powder were cristobalite. 3) The sintered composite showed larger thermal expansion value by expansion due to the transition of cristobalite followed with the crystallization of cristobalite than that without crystallizing property.
研究了添加石英对由玻璃料、玻璃粉和石英粉制成的粉末压块烧结过程的影响。所得结果总结如下:1)石英粉对玻璃料和玻璃粉的收缩曲线及烧成温度范围有一定影响。与其他玻璃料和玻璃粉相比,派热克斯玻璃粉对添加石英的粉末压块的烧成温度范围影响更大。2)由派热克斯玻璃粉和石英粉制成的粉末压块在热处理过程中产生的晶体是方石英。3)与没有结晶性能的烧结复合材料相比,由于方石英转变并结晶导致膨胀,烧结复合材料显示出更大的热膨胀值。
