Description of Silicon Carbide Brick Silicon carbide bricks are refractory products made of silicon carbide as the main raw material. Silicon carbide content is 72%~99%. Generally, black silicon carbide (with more than 96% SiC content) is used as raw material, with binder (or without binder) added, and is prepared through batching, mixing, molding, firing and other processes. The main crystalline phase is silicon carbide. The main varieties are 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.
Feature Of Silicon Carbide Brick 1.Good thermal conductivity, 2.Good high temperature strength, 3.Wear resistant and erosion resistant, 4.Good thermal shock resistance, 5.Good corrosion resistance, 6.Good oxidation resistance.
High Quality Silicon Carbide Blocks Standard sizing: 230 x 114 x 65 mm ,Special size and OEM Service also provide! The size is precise, providing kinds of shapes according to customer's drawing
