Black Silicon Carbide Description

Silicon carbide is a non-metallic mineral product formed from quartz sand (SIO2) and anthracite or petroleum coke (C) as basic raw materials under high temperature conditions above 1800 degrees Celsius. It has high hardness, low expansion coefficient, chemical stability, certain toughness, and good thermal conductivity. It is widely used in consolidation abrasives, coated abrasives and free grinding, electronic product grinding, refractory materials, special ceramics, foam ceramics, coating and plastic addition and modification, auto parts, military aviation, deoxidizer for steelmaking, etc.

Production Process

Raw Material Crushing

High purity silica (usually quartz or sand) and carbon (usually petroleum coke or coal) are ground to produce fine powder.

Smelting Silicon Carbide

Heat the furnace to a high temperature (approximately 2000 to 2500 degrees Celsius) in an inert atmosphere or vacuum.Heat causes a reaction between carbon and silicon dioxide, producing silicon carbide.

Ingredients And Mixing

Mix the fine powder of silica and carbon in the required proportion and press it into the desired shape to form a mixture.

Cooling And Solidification

Lorem ipsum dolor sit amet consectetur adipiscing elit dolor

Electric Furnace Preparation

Place the mixture in a resistance furnace, commonly known as the Acheson furnace.

Product Classification

The cooled product is then crushed, ground, and classified into the required particle sizes.
