SentroTech Silicon Carbide Products

SentroTech offers Sintered Alpha Silicon Carbide Products. Alpha silicon carbide material is most commonly used in sintered products in industrial application. It is formed by mixing very fine silicon carbide powder with non-oxide sintering additives at sintering temperature between 2000^oC to 2600^oC under vacuum or inert atmosphere to form very dense products. Silicon carbide parts can be formed by dry press, extrusion, isostatic press and injection moulding. Various complicated shapes can be formed by these process technologies. Due to its very fine gain size and high density, sintered alpha silicon carbide product has excellent surface finishing and tight dimensional control that require non or minimum after-sintering machining.

Sintered Alpha Silicon Carbide Products offer very unique properties which include:

• High hardness next to diamond.
• Extremely wear and abrasion resistance.
• High flexural strength at room or high temperature.
• Excellent thermal shock resistance due to its low thermal expansion and high thermal conductivity.
• Excellent corrosion resistance.
• High temperature resistance.

Typical Application Of Sintered Alpha Silicon Carbide Products

• Wear and abrasion resistance tube and parts for power industry.
• Corrosion resistance parts for chemical and paper industries.
• Oil extraction parts in oil drilling industry.
• Automotive components, mechanical sealing and sealing ring.
• Heat exchange tubes.
• Structure materials and crucible for semiconductor industry.
