200 Mesh Mullite Powder of Refractory Products for Refractory and Precision Casting Industry (Grade I-III)
Mullite powder of refractory products is made of kaolin by high temperature sintering. The density of mullite is generally greater than 2.5g/m3, the true specific gravity is 2.6g/cm3, the water content is less than 0.03%, and the fire resistance is greater than 1750 ℃. Under the condition of high temperature burning, its weight will be reduced by 0.3% and not more than 0.4%, which shows the stability of mullite's chemical properties. Its pH value is between 7 and 9, and the hardness of the shell is greater than 8 MPa.
