Reaction bonded silicon nitride is made by direct nitridation of a compacted silicon powder,and because of the difficulty of ensuring complete reaction; it is hard to achieve a high component density of ensuring complete reaction; it is hard to achieve a high component density.Usual densities are in the range 2.3 – 2.5g/cm3 compared with 3.29g/cm3 for gas pressured sintered silicon nitride.The higher density gives the HPSN, SSN & GPS-SSN materials better physical properties and means they are used in more demanding applications at very high temperature,especially for non-ferrous molten metal handling and thermocouple sheaths.  The nitridation produces only a small volume change, which means that RBSN components do not need to be machined after fabrication and complex near net shapes can be produced  in a single process stage.

Key Applications of si3n4 roller

1.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.

2. 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

3. 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.

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

5.  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.

6. 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.

7. 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.
