由于焙烧氢氧化铝,可采用多种现代化设备,以及对各种牌号氧化铝提出有各种粒度要求,从而有必要探讨氢氧化铝热处理速度对氧化铝粒度组成的影响。目前,实际上没有关于这方面问题的文献资料。因为,氢氧化铝在脱水蒸发时,煅烧过程中常伴有明显的粉尘逸出现象,所以在确定研究方法时,考虑了上述现象。氢氧化铝称样是在密封的石英容器内煅 Due to calcination of aluminum hydroxide, a variety of modern equipment can be used, as well as a variety of particle size requirements for various grades of alumina, so it is necessary to explore the effect of the heat treatment speed of aluminum hydroxide on the particle size of alumina. At present, there is virtually no literature on this issue. Because, aluminum hydroxide dehydration evaporation, the calcination process often accompanied by obvious dust escape phenomenon, so in determining the research method, consider the above phenomenon. Aluminum hydroxide is said to be calcined in a sealed quartz container
