Customized silicon nitride ceramic dark gray polysilicon ceramic
Silicon nitride ceramics have excellent comprehensive performance:
1. Very strong corrosion resistance, in addition to concentrated HF, it can be used in other strong acids and alkalis.
2. High temperature resistance, when it can withstand 1200℃ in an oxidizing atmosphere, it can withstand a maximum of 1500℃ in a reducing atmosphere.
3. Non-magnetic, electrical insulation, low thermal conductivity, can be used for insulating materials.
