Nitride bonded silicon carbide is widely used as thermocouple thermowell in thermometric system of nonferrous metal melting furnace.It has the following characteristics:
1. Excellent thermal conductivity, thin tube wall (only a few millimeters), very fast response to temperature, can measure the temperature of liquid metal in one minute;
2. It will not melt at high temperature and will not pollute the liquid metal;
3. Excellent thermal shock resistance, oxidation resistance and thermal shock resistance;
4. Very strong corrosion resistance,and erosion resistance;
5. It is electrical insulator;
6. High temperature resistant and good thermal expansion.
