Silicon Nitride has the most versatile combination of mechanical, thermal, and electrical properties of any technical  ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal  shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination  of creep and oxidation resistance and high strength. Additionally, its low thermal conductivity and high wear  resistance make it an excellent material that can withstand the toughest of conditions in the most demanding  industrial applications. Silicon Nitride is an excellent choice when high-temperature and high-load abilities are  needed. 

 Key Applications of Silicon Nitride

 Automotive: Bearings, Tappet Shims & Buckets, Cam Rollers, High pressured pumps parts, Turbocharge Rotors,  Rocker arm tips, Welding location pins, Squeeze Rollers for radiator tube manufacturing etc. for its superior  mechanical reliability and wear resistance and corrosion resistance

 Balls & Bearings: Fully dense various size balls from o.5mm up to 50mm OD, Fully dense ceramic Bearing, Roller  Bearing, Tapper Roller bearings & Plain Bearings for 60% lighter weight, electrical- magnetic insulating, 70% higher  speed, chemical resistance, high temperature etc. Also Hybrid bearing having ceramic Balls & rollers for high  strength

 Non-ferrous Foundries: Thermocouples sheaths, Riser Tubes, Heater Tubes, Valve rods, Valve seats, aluminium  powder atomizer tubes, Molten metal pumps parts, Rotor for de-gassing shaft, Launders due to high temperature  capacity, excellent thermal shock, non-wetting properties

 CMM: Various types of styluses, styluses rods, Plain bearings, Ceramic balls etc.

 Oil & Gas Industries: Sleeves, Plungers, Needles, compression Rings, seals etc. are used for the harsh  environment  produces chemical, wear, corrosion and high temperature challenges that can be met through the use  of dense  silicon nitride

 Nuclear & Defence: Due to lightweight, hard wear and toughness, this advanced ceramic are used as a were  resistance tiles, impact plates, discs, ring etc. and also used for personnel body armors, vehicle, vessel, helicopter  and aircraft etc. applications

 Electrical & Electronics: A large variety of high performance parts are manufactured for the electrical electronic  industry due ti insulating and non-magnetic properties. Parts include wafer processing components, microwave  specialty ceramics etc.
