Product Description


Fine Si3N4 bonded SiC  High Temperature thermocouple protection tube is a sort of structure ceramic material, NSiC product is shaped by casting with the composition of high pure SiC and Si powder, and sintered through nitrified reaction.


NSiC has higher strength than RSiC and has excellent oxidation resistance. Maximum working temperature is 1500deg.In addition to its structural properties, NSiC has excellent wear properties and is resistant to corrosion and erosion by molten metals. So  High Temperature thermocouple protection tube can be used in direct contact with molten aluminum, zinc, copper, magnesium. NSiC  thermocouple protecting tubes has been successfully used for protection tubes for temperature measurement.


NSiC offer many engineering property levels that are not found in other refractory materials, such as high strength at using temperature, excellent load bearing strength and resistance to chemical and abrasive attack.
