  • Introduction and application of silicon nitride ceramics ...

    1. Brief introduction of silicon nitride ceramics. Silicon nitride (Si3N4) is a covalently bonded compound that has two crystal types, α-Si3N4 and β-Si3N4. α-Si3N4 is acicular crystal, β-Si3N4 is granular crystal, both belong to hexagonal crystal system. White or off-white α-Si3N4 can be obtained by nitrifying high purity Si at 1200~1300℃, and nitrated at 1450℃ chemical temperature so ...

  • What are full ceramic bearings used for?

    Due to the higher cost, full ceramic bearings are only used where steel or stainless steel bearings cannot cope.Full ceramic bearings are ideal for use in corrosive environments. Consider the marine industry as an example. Unlike stainless steel, ceramic bearings are extremely corrosion resistant and can operate for long periods of time — even when fully submerged — in seawater.
