Product Description

Fine Si3N4 bonded SiC High Temperature  Protective 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  Protective tube can be used in direct contact with molten aluminum, zinc, copper, magnesium. NSiC Thermocouple protection tubes has been successfully used for  Protective tube 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. 

Advantage

1. Excellent oxidation resistance
2. Good wear resistance
3. Excellent corrosion resistance
4. High temperature flexural performance
5. Excellent load bearing strength 

Application

NSiC  Protective tube can be used in direct contact with molten aluminum, zinc, copper, magnesium. NSiC Thermocouple protection sheath has been successfully used for  thermocouple protective tubes for temperature measurement.
