china supplier low price cement clinker alumina powder 0.6-50 micro meter as additive for monolithic refractory
china supplier low price cement clinker alumina powder
AW series α-AL2O3 activated calcined alumina, on the basis of establishing the control model of fine particle size, effectively controls and optimizes the particle size distribution. Meanwhile it makes phase change and surface modification to own small crystal grain size and crystal-like, spherical-like properties.
