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 ℃.

Whether the customer is satisfied or not depends on the customer's feeling after comparing the perceived effect of a ball milling media high density alumina ceramic media, ceramic insulated beads for heating elements, ceramic capillary tube or service with his expectations. In the future, we will continue to grow steadily and gradually expand the market share of our products. The company creates a commercial space image of higher grade, more personality, and higher quality for customers, tailors the most suitable products, and continuously optimizes service measures, and strives to create greater product added value for customers. We develop new and good industries, strengthen and optimize enterprises, and better fulfill their economic and social responsibilities.

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
