Silicon carbide used in industry is a synthetic material, commonly known as emery. Silicon carbide is one of the most commonly used non-oxide refractory raw materials in the field of refractories. Clay-bonded silicon carbide, oxide-bonded silicon carbide, silicon nitride-bonded silicon carbide, recrystallized silicon carbide, reactive sintering silicon carbide and other products produced from silicon carbide
And amorphous refractories are widely used in blast furnaces, zinc smelting furnaces in metallurgy industry, kiln furniture in ceramic industry, etc.
Silicon carbide is available in black and green varieties. The content of SiO2 in the siliceous raw material is as high as possible and the impurity content is as low as possible when treating green silicon carbide; while the content of SiO2 in the production of black silicon carbide raw material can be slightly lower.
In the production of advanced silicon carbide refractories such as Si3N4-SiC, recrystallized SiC (R-SiC) and reactive sintered silicon carbide (Sisic), it is best to use shaped SiC sand. In the production of silicon carbide kiln furniture of the above materials, shaped SiC sand is widely used abroad, and the density, strength and oxidation resistance of kiln furniture have been significantly improved.

Silicon carbide uses
1. Main use: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials.
2. Chemical industry, abrasives industry, steel industry, etc.
Silicon carbide is also called moissanite. Among contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is the most widely used and most economical one, which can be called gold steel sand or refractory sand. At present, China's industrially produced silicon carbide is divided into two types: black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20-3.25 and a microhardness of 2840-3320kg/mm2.
Anchor bricks are anchor bricks for industrial kilns. The electric furnace roof is a furnace roof structure supported by metal hanging bricks and refractory bricks. Therefore, the leakage of reactive gas and hot gas in the furnace will damage the metal hanging parts, thereby causing furnace damage. roof collapse accident. Anchor bricks are also called hanging bricks and anchors.
Chrome corundum brick refers to corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than that of pure corundum products.
