Full Ceramic Si3n4 Silicon Nitride Zro2 Zirconia Bearing 1621 2RS R16 2RS
Si3N4 Ceramics is a new type of non-metallic ceramic material. It is characterized by high strength at room temperature and high temperature, and the strength of Si3N4 can be maintained at 1200 ℃.
We identify various unmet needs to explore market opportunities and thus develop or improve our ceramic fiber module installation, full ceramic zro2 si3n4, fiberfrax ceramic paper fiber and services to meet customer needs. We always understand that we are making products that customers need, not products approved by ourselves. We are currently a leading manufacturer in sales, a model brand in China, and a well-known enterprise with great influence in the industry.
Product Description
Si3N4 Ceramics is a new type of non-metallic ceramic material. One of the popular product of Si3N4 ceramics is Si3N4 tube. The tubes are mainly used in conjunction with thermocouples to protect them. It allows the thermocouple to operate properly in special environments and to resist high pressures and high flow rates.
Process Method
It uses silicon powder as raw material and is first made into the desired shape using the usual molding method. Initial nitriding is done in nitrogen at 1200°C, so that part of the silicon powder reacts with nitrogen to form silicon nitride. This way the whole body already has some strength. It is then nitrided a second time in a high-temperature furnace at 1350°C to 1450°C to react with the silicon nitride.
Specifications
Thermocouple protection tube: diameter Φ12-80mm, length 600-1800m
