Silica mullite brick color
The color of Silica mullite bricks has a certain relationship with the firing temperature, but the most important thing is the firing atmosphere. During the firing process, the reducing atmosphere is most suitable for the firing of Silica mullite bricks. If the firing temperature is in an oxidizing atmosphere, the brick will oxidize, the surface layer will not reflect silicon carbide, and the strength will also decrease. Silica mullite bricks are characterized by wear resistance and good seismic stability, and are mostly used in the transition zone before and after cement rotary kilns.
Silica mullite bricks have a dense structure, stable mullite and SiC crystals, and can prevent erosion by gases and molten materials. However, silicon carbide has high thermal conductivity, small thermal expansion coefficient, and good thermal and shock resistance, so the bricks are not easy to break and peel off. The performance of silicon molybdenum bricks used in cement rotary kilns is relatively better than the anti-flaking high alumina bricks and the phosphate high alumina bricks with better wear resistance.
