SILICON CARBIDE POWDER
Silicon Carbide Powder For Advanced Ceramics, FEPA Standard, JIS
and P Standard graded powder is available on request
Taking advantage of the excellent characteristics of Silicon
Carbide, such as chemical inertness at all temperatures, resistance
to thermal shock and abrasion hardness and sinterability, the
Technical Ceramics industry has developed a wide range of
applications based on Silicon Carbide. The main applications for
SiC based ceramics are kiln furniture, burner nozzles, sliding
earings, process components for the Semiconductor industry, passive
armor for the Security and Defense industries, seal rings and
Diesel Particulate Filters for the Industrial and Automotive
industries.

SiC-based ceramic components can be manufactured using several
processes:
• Nitride-bonded SiC
• Reaction bonded SiC
• Re-crystallized SiC
• Pressureless sintered SiC
• Hot press sintered SiC
Through its strong R&D and production capacity. Ceramic
Material has been a pioneer in the development of SiC powder and
ready-to-press granules for the production of technical ceramics
and composite materials in China.
We offers a full series of SiC powders with varying purity levels
and particle sizes down to the sub-micron range, which are
specifically designed to provide very high density, excellent
oxidation resistance, superior hardness, high strength and high
thermal shock resistance.
In addition to the powders, we also offers ready-to-press (RTP)
granules based on fine powders with specific surface areas
typically ranging from 10 to 15 m2/g.
Special tailor-made Powders and RTP granules are available on
request.
