High Hardness Insulation Silicon Nitride Ceramic Plate for Automotive Industry

Silicon nitride exceeds other ceramics in thermal shock resistance. Its strength does not deteriorate at elevated temperatures, hence it is most appropriate for engine and gas turbine parts, including turbo charger rotors, diesel engine glow plugs and hot plugs.

The characteristics of silicon nitride ceramics are:

• 1. Exceptional Mechanical Strength and Hardness :
  · Silicon nitride exhibits high fracture toughness and excellent wear resistance . It is significantly stronger and harder than many other technical ceramics, which prevents cracking and deformation under high-stress conditions.
• 2. Outstanding Thermal Properties:
  · High Thermal Shock Resistance : It can withstand extremely rapid temperature changes without cracking, a critical property for applications involving rapid heating and cooling cycles.
  · Low Thermal Expansion : Its coefficient of thermal expansion is very low , which ensures excellent dimensional stability across a wide temperature range.
• 3. Excellent Electrical Insulation:
  · Silicon nitride is a very good electrical insulator , even at high temperatures . This makes it ideal for isolating conductive components in electronic devices.
• 4. High Chemical and Corrosion Resistance:
  · It is highly inert and resistant to corrosion from most acids , alkalis, and molten metals , ensuring long-term reliability in harsh environments.

Silicon Nitride Application:

• electronics manufacturing

Used as an insulation layer or support structure to protect sensitive components during high-temperature processing in semiconductor manufacturing and other electronic components.

• high-temperature furnace
