Sintered Refractory Mullite Corundum Brick/ Wholesale Glass Blocks for Hi-Temp industrial furnace is fused from high quality bayer aluminum in high temperature. Its hardness is higher but toughness lower compared with Brown Aluminum Oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability.

Corundum mullite bricks have serious edges and corners missing in
the grinding process, and the reasons are as follows:
1. Hardness.Hardness is usually considered as an important index to
measure the wear resistance of materials.The harder the material,
the better its wear resistance, but in the case of large impact
wear, hardness does not necessarily have a very large
effect.Firebrick is heterogeneous and the hardness of each part may
vary.For the refractory bricks containing corundum and silicon
carbide, if the bonding strength is sufficient, when the wear of
the easy wear materials with low hardness, these high hardness
materials can still resist the wear of the refractory brick.
2, crystal structure and crystal solubility.Materials with a
particular crystal structure have better wear resistance, such as
cobalt with a tightly arranged hexagonal structure has a small
coefficient of friction and wear resistance.Metallurgical poorly
miscible metals have good wear resistance to each other.
3, intensity.Firebrick will encounter a lot of impact wear in the
process of use, therefore, high strength firebrick resistance to
wear.
4. Volume density.Refractories with high bulk density and low
apparent porosity have high wear resistance.
5. Temperature.Temperature has an influence on the hardness,
solubility and reactivity of the material, thus indirectly
affecting the wear resistance of firebrick.In general, the
solubility and reactivity increase with the increase of
temperature.Firebrick is used under high temperature, the wear
resistance under high temperature is very important.
6. Atmosphere.Similar to the effect of temperature, atmosphere
affects the mutual solubility and reactivity between materials,
thus affecting their wear resistance.
