Series KT-B of the micropowder α-Al₂O₃ of high quality was the " 95 " key task project of the state. THe project was undertoken by our company together with NanJing Institute of Chemical Technology.Its praise at the state level was adopted in 1994 and its level reached the advanced one of the state.The products are charactrized by great activity, micro grain size and complete phase transformation etc.and are the necessary raw materials for fine ceramics and castable refractory materials in high quality.
