Silicon nitride ceramics have various important applications in the field of mechanical engineering, mainly reflected in the following aspects:

High temperature components: Silicon nitride ceramics have excellent high-temperature resistance and can be used to manufacture components in mechanical engineering that need to withstand high-temperature environments, such as high-temperature furnaces, heat treatment equipment, high-temperature sensors, etc. These components can maintain stable performance at high temperatures and are not easily softened or deformed.

Wear resistant components: Silicon nitride ceramics have excellent wear resistance and higher hardness than most metal materials, so they are often used to manufacture wear-resistant components in mechanical engineering, such as bearings, shaft sleeves, seals, etc. These components can reduce friction losses and extend the service life of the equipment.

Chemical stability: Silicon nitride ceramics have good chemical stability and are not easily corroded by acidic or alkaline chemicals. Therefore, they are often used to manufacture corrosion-resistant components in chemical engineering equipment, such as chemical reaction vessels, pipelines, valves, etc. These components can protect the equipment from corrosion by chemical media and improve its service life.

Lightweight design: Compared to metal materials, silicon nitride ceramics have a lighter density, which can be used to manufacture lightweight mechanical components, reduce equipment weight, improve transportation efficiency and ease of use.

Insulation material: Silicon nitride ceramics have excellent insulation properties and can be used as insulation materials in mechanical engineering, such as electrical insulation parts, thermal insulation parts, etc. These components can prevent the conduction of current or heat, protecting the safety of equipment and operators.
