What are the application fields of high-strength and high insulation alumina ceramics

---

High strength and high insulation alumina ceramics (Al ₂ O ∨ ceramics) are high-performance ceramic materials with excellent mechanical strength, high insulation, high temperature resistance, corrosion resistance and wear resistance. Because of its excellent comprehensive performance, it has been widely used in many industrial fields, and solved the problem of insufficient performance of traditional materials in extreme environments.

Characteristics of alumina ceramics with high strength and high insulation
Before introducing specific applications, let’s first understand its core features, which determine its wide application:

1. High strength: high hardness, high bending strength and wear resistance.
2. High insulation: high resistivity, high dielectric strength, suitable for high-voltage environment.
3. High temperature resistance: it can work stably under high temperature above 1600 ℃.
4. Corrosion resistance: It has strong resistance to acid, alkali and chemical solvents.
5. Low thermal expansion coefficient: good dimensional stability, suitable for precision devices.
