Overview
Silicon carbide (SiC) is one of the most attractive ceramic materials because of its excellent mechanical properties such as high strength, moderate toughness, and high wear and oxidation resistance, and strength retention at elevated temperature. ARCI has the expertise to manufacture SiC parts with various size and shapes by pressureless sintering using solid-state or liquid phase sintering additives and also by hot pressing technique. SiC parts of complex geometry can also be manufactured through machining at the green stage using 5-axis CNC machine. Dimensional accuracy can also be achieved on sintered SiC parts by final shaping with the help of sophisticated ultrasonic machining.
Key Features
- Tuneable density and other thermo-mechanical properties.
- Flexibility in producing SiC parts incorporating solid-state or liquid phase sintering additives.
- Capable to produce SiC components up to 750 mm diameter.
- SiC parts with critical can be manufactured.
