98% black silicon carbide 0-1mm for self-bonded silicon carbide refractory bricks
Self-bonded silicon carbide refractory components have advantages such as good high-temperature resistance, chemical corrosion resistance, and high-temperature mechanical properties. The main raw material for this type of silicon carbide refractory material is a mixture of 98% silicon carbide powder and silicon carbide particles, usually 0-1mm in size. Some manufacturers also choose models such as 0.2-1mm and 1-2mm. Self-bonded refractory silicon refractory materials, such as refractory bricks, silicon carbide turbines, silicon carbide pump bodies, etc., generally have better comprehensive thermodynamic performance than refractory materials mixed with boron nitride or corundum.
The excellent performance of refractory bricks or ceramic components containing silicon carbide mainly comes from silicon carbide raw materials, which are mainly reflected in the following aspects:
1. Enhance the thermal shock resistance of brick materials: Black silicon carbide has high-temperature stability, which can increase the cold and hot cycle resistance of refractory bricks, reduce cracking and delamination, and improve the refractory performance of brick materials.
2. Improve the mechanical strength of refractory bricks: Black silicon carbide has high hardness and strength, which can increase the compressive strength, bending strength, and wear resistance of refractory bricks, and extend their service life.
3. Inhibition of sintering shrinkage: Black silicon carbide has a low coefficient of thermal expansion and a stable volume at high temperatures, which can offset the shrinkage of other components in refractory bricks and form a microporous structure, improving the permeability and slag resistance of the brick material.
