ALPW-AF-CA calcined alumina is made of first-class industrial alumina powder, which is calcined in a high-temperature tunnel kiln and then processed by a ball mill to obtain aluminum oxide powder. It has the characteristics of high purity, stable high-temperature performance, uniform calcination, good fluidity, and good sintering performance. It is a high-quality raw material for refractory materials and ceramic products.
