Unique Bargains 1/8 Inch Ceramic Bearing Balls Si3N4 Silicon Nitride Ball G5 Precision 50 Pack

Silicon nitride ceramic is a kind of inorganic material ceramic. The strength of silicon nitride is very high, especially hot pressed silicon nitride, which is one of the hardest substances in the world. Si3N4 ceramic is a covalent compound, the basic structural unit is a tetrahedron of [SiN4], the silicon atom is located in the center of the tetrahedron, and there are four nitrogen atoms around it, which are located in the four vertices of the tetrahedron, and then in the form of each three tetrahedron sharing one atom, forming a continuous and sturdy network structure in three-dimensional space The theoretical density of Si3N4 is low, and it is much lighter than steel and engineering ultra-heat resistant alloy steel, so it is very suitable to replace alloy steel with Si3N4 ceramics in those places that require materials with high strength, low density, high temperature resistance and other properties
