Silicon Nitride Ceramic Insulation Ring Used In Polysilicon Industry


Product Overview

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.

Product Picture

  1. High temperature resistance. At 1200 ℃, the strength and hardness are almost unchanged. It can be used in a high temperature environment. It will not melt under high temperature and will not decompose until 1900 ℃.
  2. Non-magnetic, electrical insulation, low thermal conductivity, can be used for insulating materials
  3. Low density (3.26G/CM3), light weight, higher strength and hardness than general ceramic materials, can be used as wear-resistant materials.
