Alumina ceramic manufacturers : Application of silicon nitride ceramics in the aerospace field

Silicon nitride ceramics are high-performance ceramics that are widely used in the aerospace field. Compared with alumina ceramics, silicon nitride ceramics have higher hardness, better wear resistance and higher thermal stability. In the field of aerospace, silicon nitride ceramics are widely used in the manufacture of high-temperature parts, such as jet engine turbine blades and guide vanes, high-speed aircraft thermal structural parts, etc.

Silicon nitride ceramics have the following advantages:

1. High hardness: The hardness of silicon nitride ceramics is more than 30% higher than that of alumina ceramics, and can be used to manufacture high-strength and high-rigidity parts.

2. Good wear resistance: Silicon nitride ceramics have better wear resistance than alumina ceramics, and can be used to manufacture high-speed rotating parts.

3. Good thermal stability: The thermal stability of silicon nitride ceramics is better than that of alumina ceramics, which can be used to manufacture high-temperature parts.

, silicon nitride ceramics are widely used in the manufacture of high-temperature parts, such as jet engine turbine blades and guide vanes, high-speed aircraft thermal structural parts, etc. These parts need to have high strength, high stiffness, high wear resistance and high thermal stability, and silicon nitride ceramics just meet these requirements.

For example, jet engine turbine blades and guide vanes need to withstand the test of high temperature, high pressure and high speed rotation, and silicon nitride ceramics have high hardness and wear resistance, and can withstand such an environment. Similarly, high-speed aircraft thermal structural parts need to have high thermal stability and high strength, and silicon nitride ceramics are also suitable for such applications.

Alumina ceramic manufacturers: the manufacture of silicon nitride ceramics

The manufacture of silicon nitride ceramics requires the use of high-purity silicon powder and nitrogen. Silicon powder and nitrogen are mixed first, and then reacted under high temperature and pressure to form silicon nitride ceramics. The manufacturing process requires very precise control to ensure the high quality of the silicon nitride ceramics produced.

Silicon nitride ceramic is a high-performance ceramic with excellent hardness, wear resistance and thermal stability. In the aerospace field, silicon nitride ceramics are widely used in the manufacture of high temperature parts. With the continuous advancement of technology, the application fields of silicon nitride ceramics will continue to expand.
