Calcium Aluminate Clinker

Calcium Aluminate Clinker is made from Calcium,Aluminium and little quantity other raw material,mixed in proper

proportion,and fused.The composition of the main phase:C12A7,C3A,C2S etc.

1.Low melting point,Low Melt dreg viscidity,high mobility,short time become dreg.

2.High Dreg and material sulphur,good desulphurization,dephosphorization,deoxidation,It can absorb the impurity.

3.Widely used in the process of LF,SKF,VHP,it can increase the life-span of the ladle.

Series KT of reactive a-Al2O

3micropowder were the "8.5" key tasy task project of the state.Its praise at the state level was adopted in 1994

and its level reached the advanced one of the state.The products are characterized by great activity,micro grain size and complete phase

transformation etc.and are the necessary raw materials for fine ceramics and castable refractories in high quality.
