Silicon Nitride Plate Description

Silicon Nitride (Si₃N₄) is an advanced high-performance ceramic known for its exceptional mechanical strength,

thermal shock resistance, and chemical stability. Our precision-engineered Si₃N₄ square plates are ideal for

demanding industrial, semiconductor, and high-temperature applications where reliability is critical.

Data Sheet & Typical properties of silicon nitride material:

Performance Advantages

✔ Extreme Durability – Superior wear and impact resistance compared to alumina or zirconia.
✔ Thermal Shock Resistance – Withstands rapid temperature changes without cracking.
✔ Corrosion & Erosion Resistance – Ideal for harsh chemical and abrasive environments.
✔ Electrical Insulation – Excellent for high-voltage and high-frequency applications.
✔ Lightweight & High-Stiffness – Perfect for precision engineering and structural components.

Typical Applications

Semiconductor & Electronics

Wafer handling, heater plates, insulators, and electrostatic chucks (ESCs)

Industrial & Mechanical

Bearings, cutting tools, wear plates, and pump components

Energy & Aerospace

Turbine blades, heat exchangers, and radomes

Research & Laboratory

High-temperature furnace fixtures, crucibles, and custom ceramic parts

Packing & Delivery

As a ceramic material, silicon nitride is quite fragile in a lot of cases. Our silicon nitride plate & sheet

are carefully handled to minimize damage during storage and transportation. Suitable outer boxes

and inner cushioning materials are used for Si3N4products, vacuum packing is also engaged for some of the parts.
