Silicon Nitride

• Industry application technical index advantages

1. Power electronics and semiconductors:

High thermal conductivity and low thermal expansion coefficient, suitable for high power density devices (such as SIC, GAN modules), heat dissipation efficiency increased by more than 30%.

2. Aerospace:

High temperature resistance (> 1000℃) and lightweight (density 3.2 G/CM³) are used for engine thermal protection components and satellite power systems.

Lightweight: density 3.2 G/CM³, lighter than alumina (3.9 G/CM³), suitable for aerospace weight reduction requirements.

3. Mechanical manufacturing:

High hardness and wear resistance, used in ceramic bearings, turbine blades, life extended by more than 3 times.

4. Chemicals and energy:

Corrosion resistance and resistance to molten metal are used in electrolytic cell lining and polysilicon production equipment to improve process efficiency.

5. Biomedicine:

High biocompatibility for use in artificial joints and dental implants to reduce rejection.

• Industries that are particularly suitable

1. New energy vehicles: electronic control system, charging pile heat dissipation substrate (accounting for 75.8% of global demand).
2. High frequency communication: 5G base station RF devices, millimeter wave radar, suitable for high frequency and low loss requirements.
3. Aerospace: engine nozzles, thermal protection systems, tolerance to extreme temperatures and radiation.
4. High-end equipment manufacturing: precision bearings, cutting tools, improve the durability of equipment.
5. New energy and photovoltaic: Polysilicon reaction vessel, solar cell module, optimize production efficiency and reliability.
