Silicon nitride ceramics are mainly used as one of the hardest materials in the world, and have been applied by many enterprises. In recent years, with the continuous development of my country’s industry, the technology of producing silicon nitride ceramics has become better and better. There are more and more enterprises. , so today Pintejin Ceramics will share with you the specific properties of silicon nitride ceramics, so that both manufacturers and acceptance units can use it as a reference.
Pintejin Ceramics specializes in the production of alumina, titania, zirconia and silicon carbide special ceramic parts. The company takes high starting point, high quality as the standard, strict selection of materials and standardization of production processes to ensure the stability of product quality. The products are widely used in textiles , electronics, electrical appliances, machinery, aviation, aerospace and other fields. If you want to know more about our products, you can come directly to our company for a deeper understanding. Contact Pintejin Ceramics Tel: +86 769 82886112.
First of all: Silicon nitride ceramics is a very high temperature resistant material and is reused in many industries. At the same time, silicon nitride ceramics have no melting point under normal pressure. When the temperature reaches 1870 °C, silicon nitride ceramics will directly decompose When we actually use it, once the temperature under normal pressure reaches 1200 degrees Celsius, the C mechanical hardness of silicon nitride ceramics will be greatly reduced.
Secondly: as one of the hardest materials in the world, silicon nitride ceramics have high hardness and good wear resistance, and also have a very low coefficient of friction. The surface is very smooth and does not require professional polishing, etc.
We must understand this clearly. The third advantage of silicon nitride ceramics is that they have high thermal shock resistance. When the temperature of silicon nitride ceramics reaches a thermal shock of one thousand degrees Celsius, silicon nitride ceramics will No cracking occurs, and the thermal conductivity of silicon nitride ceramics is high and the thermal expansion coefficient is relatively small.
The strong corrosion resistance of silicon nitride ceramics is mainly because the chemical stability of silicon carbide ceramics is very strong, and basically does not produce any chemical reaction with other inorganic acids, except for hydrofluoric acid, which can be fully explained Silicon nitride ceramics have high acid resistance, and silicon nitride ceramics are not easily oxidized.
Finally: Another feature of silicon nitride ceramics that needs attention is that it is relatively brittle, so when silicon nitride ceramics are actually used, silicon nitride fibers will be used to increase the toughness of silicon nitride ceramic materials.
The five points mentioned by the editor just now are the basic characteristics of silicon nitride ceramic materials. With the innovation of silicon nitride ceramic technology and the actual use environment, silicon nitride ceramic materials will also have other characteristics. Therefore, both production and acceptance should understand the knowledge mentioned above. Pintejin Ceramics is a company specializing in the development, design, molding, sintering, production and sales of advanced (zirconia ceramics, alumina ceramics, silicon nitride ceramics) precision ceramic products.
