Applications:
Silicon Nitride Ceramics, or SI3N4 ceramic balls, are a type of ceramic material that possesses excellent thermal, electrical, and mechanical properties. With its place of origin being China, this ceramic material has a thermal conductivity ranging from 25-35 W/m.K, breakdown voltage from 20-25 KV/mm, density from 3.2-3.3 G/cm3, thermal expansion coefficient from 3.2-3.5 X 10-6/K and Poisson's ratio from 0.25-0.3.
As a result of these advantageous features, SI3N4 ceramic balls are commonly used in a variety of applications. For example, they are used as electrical insulators in power electronics due to their high insulation, electrical breakdown voltage, and low dielectric loss. They are also used as wear-resistant parts in mining, petroleum, and chemical industries due to their excellent mechanical properties and chemical compatibility. In addition, SI3N4 ceramic balls are used in turbine blades and engines in the aerospace industry due to their high heat-resistance and thermal shock resistance.
In summary, SI3N4 ceramic balls are a type of ceramic material that originates from China and have unique thermal, electrical, and mechanical properties. Their excellent characteristics make them suitable for a variety of applications, such as electrical insulation, wear-resistance, heat-resistance, and thermal shock resistance.
