Advanced Ceramics & Composites


CGCRI is the pioneer in research on non-oxide ceramics in India and has the cutting edge in this field. The materials dealt with are silicon nitride, SiAlONs, AlON, aluminum nitride, silicon carbide and composites with carbon fiber and CNT having an aim to use the materials in low and high temperature structural applications. The products developed are dense silicon nitride ball for hybrid bearing and other wear resistant components, aluminum nitride as impact resistant material, AlON for visible and IR transparent windows, reaction bonded silicon nitride porous tube for acid electrolysis, hexagonal boron nitride powder for high temperature lubrication. Present work includes both basic research and product development on multi-layer composite, carbon fiber reinforced wear resistant auto clutch component, hard SiAlON cutting tools, bio-mimetic silicon carbide high temperature filter. The division also possesses equipment for room temperature and high temperature mechanical property evaluation at macro- to micro-levels. Correlation of material-microstructure-property is the other area of research of the division.

Divisional Facilities

High Pressure Abrasive Waterjet Machine for Hard Ceramic Cutting

CGCRI, Kolkata procured a very high pressure waterjet cutting machine that operates at a maximum pressure of 6200bar. The high pressure water-abrasive mixture is ideal for cutting very hard ceramics, composites and glass products. The machine is installed for the first time in the eastern region and such a high pressure machine is the first of its kind in India. The machine will be utilized in many in-house projects and for outside agencies in future.
