Black Silicon Carbide High Temperature Strength Wear Resistance
Black silicon carbide is made of quartz sand and petroleum coke as the main raw materials, and is smelted at high temperature in a resistance furnace. It is black crystal, brittle and sharp, and has certain thermal conductivity and electrical conductivity. The microscopic shape is hexagonal crystal. The Mohs hardness of silicon carbide is 9.3, the microhardness is 2940-3300 kg/mm2, and the Knoop hardness is 2670-2815 kg/mm2. Among abrasives, it is higher than corundum and second only to diamond, cubic boron nitride and boron carbide. The density is generally considered to be 3.20-3.25 g/cm3. The natural bulk density of silicon carbide abrasive is between 1.2-1.6 g/cm3, and the specific gravity is 3.20-3.25 g/cm3.
Product Description
Silicon carbide bricks are refractory products made of silicon carbide as the main raw material. The silicon carbide content is 72%~99%. Generally, black silicon carbide (SIC content 96% or more) is used as the raw material, and a binder (or no binder) is added. It is made through the processes of batching, mixing, molding and firing.
Basic characteristics
Good wear resistance and erosion resistance,
High high temperature strength, good thermal shock stability,
High thermal conductivity, small thermal expansion coefficient, etc.
It is a high-performance refractory material.
Typical applications
The main varieties include oxide-bonded silicon carbide bricks,
carbon-bonded silicon carbide bricks,
nitride-bonded silicon carbide bricks,
self-bonded silicon carbide bricks,
recrystallized silicon carbide bricks and semi-silicon carbide bricks, etc.
