Silicon nitride is very strong, especially hot pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density and high temperature resistance.
Si3N4 ceramic is a covalent bond compound. The basic structural unit is a [SiN4] tetrahedron. The silicon atom is located at the center of the tetrahedron. There are four nitrogen atoms around it, which are located at the four vertices of the tetrahedron, and then every three A tetrahedron shares the form of an atom, forming a continuous and robust network structure in three dimensions.
Many of the properties of silicon nitride are attributed to this structure. Si3N4 has two crystal structures of α and β, all of which have a hexagonal crystal shape, and its decomposition temperature is 1800 ° C in air and 1850 ° C in 110 MPa nitrogen. Si3N4 has a low thermal expansion coefficient and a high thermal conductivity, so its thermal shock resistance is excellent. The hot-pressed sintered silicon nitride is heated to 1000 ° C and then put into cold water without cracking. At less high temperatures, Si3N4 has higher strength and impact resistance, but it will break with the increase of use time above 1200 °C, which will reduce the strength and fatigue damage at 1450 °C, so Si3N4 The use temperature generally does not exceed 1300 ° C. It has amazing chemical resistance, is resistant to almost all inorganic acids and less than 30% caustic soda solution, and is resistant to many organic acids. It is also a high-performance electrical insulation material.
Si3N4 has a low theoretical density and is much lighter than steel and engineering superalloy steel. It is because of the excellent properties of Si3N4 ceramics, so it is used in places where high strength, low density and high temperature resistance are required. Si3N4 ceramics are a good alternative to alloy steel. It is often used to make mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds.Product Image:Service:1. Can make a sample first
