CALCINED ALUMINA FOR HIGH GRADE REFRACTORY MATERIALS
Calcined Alumina For Electronic Ceramics, High A Phase Alumina Content, Low Sodium, High Whiteness
It is with high a-alumina content, high melting point, high hardness value and stable crystal form. Products made of it are with high mechanical strength, good insulating property, corrosion resistance and refractory. It is suitable for unshaped refractory production. It can increase the sintered density of the castable, reduce the moisture addition of the castable, improve its fluidity, strength and lower the rate of change.
