Due to their unique physical and chemical properties-such as high hardness, superior wear resistance, high-temperature stability, corrosion resistance, and excellent electrical insulation capabilities-ceramic components possess irreplaceable advantages in specific operating environments.
From a technical standpoint, the fabrication of ceramic components typically involves precise molding and sintering processes. Through advanced molding techniques-such as isostatic pressing and injection molding-ceramic green bodies with complex geometries and precise dimensions can be produced. Subsequently, during high-temperature sintering, the particles within these green bodies undergo densification to form a rigid ceramic structure, thereby endowing the components with their exceptional performance characteristics.
High Hardness and High Strength: Derived from the strong bonding forces of ionic and covalent bonds.
High-Temperature, Wear, and Corrosion Resistance: Possesses a stable crystal structure that is resistant to reaction with environmental media.
High Elastic Modulus and Low Coefficient of Thermal Expansion: Suitable for applications involving precision requirements and extreme operating conditions.
High Brittleness: Lacks the slip systems characteristic of metals, making it prone to brittle fracture; requires improvement through toughening techniques.
