Silicon Nitride Powder Property
A covalent bond compound consisting of silicon nitride and nitrogen (Si3N4). It was found in 1857. Silicon nitride is used extensively in aviation, military and other mechanical applications.
preparation of Silicon Nitride Ceramics
Silicon nitride is first prepared by obtaining silicon nutride powder. Once the powder has been obtained, then molds, sintering or any other methods can be used to make silicon nanorite ceramic. These methods include the following: silicon powder, liquid phase reactions method, and self propagating high-temperature synthesis method.
You can form silicon nitride ceramics by using dry pressing, cold press, or tape casting. And the main sintering process is hot pressing sintering.
Silicon Nitride Ceramics Application for Mechanical Industry
Silicon nitride cermics are used mainly as valves in pipes, pipes, grading tools, ceramic tools and other mechanical industries. In particular, the silicon-nitride ceramic bearing ball is the most common.
A silicon nitride bearing bearing ball can move at speeds as fast as 600000 revolutions a minute when used. These bearings are most often used in precision machines, motorized high-speed spindles bearings, aerospace engines as well as other equipment bearings.
This ball can be compared to a steel one.
Dense Si3N4 ceramics show high fracture toughness. high modulus, and self-lubricity. These characteristics allow them to withstand various wear environments, such as high temperature extremes and large-temperature differences.
