Silicon nitride ceramics is believed to be unfamiliar to many consumers. In recent years, with the continuous improvement of technology, the materials used in our daily lives have been improving. It is a new type of high-tech ceramics with many performance characteristics, and it is very easy to process, and the appearance looks very beautiful, which has been favored by the ceramic industry. So what are the performance characteristics of silicon nitride ceramics? 

   The main material of silicon nitride ceramics is silicon nitride, which has a very high melting point and can reach more than 2,000 ℃. Therefore,the heat resistance of the silicon nitride ceramic is very good. Because of the excellent heat resistance of silicon nitride, it has very good application prospects in mechanical manufacturing or in the field of internal combustion engine manufacturing.

   Silicon nitride is an important structural ceramic material. It is an atomic crystal with high hardness, inherently lubricious and resistant to abrasion, and resistant to oxidation at high temperatures. Moreover, it can resist the thermal shock, and is heated to above 1000 ° C in the air, and is rapidly cooled and then heated rapidly without breaking. Because of the excellent characteristics of silicon nitride ceramics, it is often used to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds. Silicon nitride ceramics are resistant to high temperatures and are difficult to transfer heat. They are used to make the heating surface of engine components, which not only improves the quality of diesel engines, saves fuel, but also improves thermal efficiency. China, the United States, Japan and other countries have developed such diesel engines.
