silicon nitride pistons Introduction:
Silicon nitride is a very important engineering ceramic which is available in several forms, each with their own unique properties. These include high strength, toughness and hardness, excellent wear resistance, corrosion resistance to many acids and alkalis and outstanding thermal shock resistance. These properties are enabling silicon nitride, and in particular SSN and sialon, to find use in many industrial applications. As the materials are becoming more widely accepted and used, new applications are being discovered all the time.
