Silicon nitride

Has one of the best combinations of toughnessand hardness of commercially available ceramics. In addition, its low thermalexpansion coefficient offers superb thermal shock resistant compared with mostother ceramics. Complex geometries can be made with sintered material. Thematerial also exhibits low density, high temperature strength, excellent wearresistance and good facture toughness. Common applications include:

- Diesel engine glow plugs

- Rocker arm pad

- Ceramic ball bearings

- Check Valves for Oil Well Applications

- Resistance Welding Fixtures

- Sand blasting nozzles

- MWD wears parts in Oil Well Drilling

- Poppet valves

- Guide rollers for steel rods and cable

- Molten Aluminum Nozzles and trim

- Valve Trim
