Factory Supply SiC Silicon Carbide Powder

Silicon carbide (SiC) powder is an artificially synthesized compound composed of carbon and silicon elements, with high hardness, high melting point, excellent chemical stability, and thermal conductivity. Silicon carbide powder is a micrometer or nanometer sized powder prepared by high-temperature smelting or chemical vapor deposition (CVD) methods, widely used in multiple industrial fields.

Application Areas 

Abrasives and polishing materials

Used for manufacturing grinding wheels, sandpaper, grinding paste, etc., suitable for precision machining of hard materials such as metals, ceramics, and glass.

Advantages: High hardness (Mohs hardness 9.2, second only to diamond and cubic boron nitride), strong wear resistance.

refractory material

Used for lining high-temperature kilns, refractory bricks in the metallurgical industry, etc., resistant to high temperatures (melting point of about 2700 ° C) and chemical corrosion.

Advantages: Good resistance to high temperatures, oxidation, and thermal shock.

Ceramics and composite materials

As a reinforcing phase added to ceramic or metal based composite materials, it improves strength, wear resistance, and high temperature resistance.

Advantages: high rigidity, low thermal expansion coefficient.

Semiconductor and electronic devices

Used for manufacturing high-temperature, high-frequency, high-power electronic devices (such as SiC wafers, diodes, MOSFETs, etc.).

Advantages: Wide bandgap (3.2eV), high breakdown electric field, high thermal conductivity, suitable for high temperature and high pressure environments.

In the field of new energy

Used in the photovoltaic industry (such as silicon wafer cutting blades), lithium battery negative electrode material coating, etc.

Advantages: Chemical inertness, extended device lifespan.

Aerospace and Military Industry

Used for high-temperature resistant coatings, missile nose cones, spacecraft insulation components, etc.

Advantages: Lightweight, anti erosion.

Environmental Protection and Catalysis

As a catalyst carrier or filter material, it is used to treat high-temperature exhaust gas or wastewater.

Core Advantages 

Extreme environmental stability

Maintain strength at high temperatures (better performance than most materials above 1600 ° C).

Acid and alkali corrosion resistance, strong oxidation resistance.

Excellent physical performance

High hardness (suitable for grinding), high thermal conductivity (good heat dissipation), low thermal expansion (size stability).
