Innovative Growth Enterprises are one of the largest suppliers of “Nitride Bonded Silicon Carbide Thermocouple Tubes” in the country. We represent Saint Gobain High Performance Materials , the inventor of Silicon Carbide in the world. Why Nitride Bonded Silicon Carbide Tubes  Precise and reliable temperature measurement is a critical requirement in any casting process. For example, the automotive industry increasingly requires suppliers to limit temperature deviations to no more than five degrees Celsius from the specified values. Thermocouples must therefore be protected by a material with a high thermal conductivity, high strength and good thermal shock resistance. CN 995 silicon nitride provides all these material properties. The material has such high strength that the wall thickness of the thermocouple protection tubes can be minimized. This is essential to detect even tiny temperature differences and permit an effective automatic control loop
