Engineering Ceramics

Engineering ceramics include multiple material families with substantially different mechanical, thermal, and electrical properties.

Common materials include alumina (Al₂O₃), zirconia (ZrO₂), silicon carbide (SiC), silicon nitride (Si₃N₄), and other specialized technical ceramics.

Alumina is frequently used for electrical insulation and wear resistance. Zirconia offers relatively high fracture toughness among technical ceramics, while silicon carbide is selected for high hardness, thermal conductivity, and wear performance.

Manufacturing methods include powder pressing, ceramic injection molding, slip casting, sintering, and precision diamond grinding.

Typical applications include electrical insulators, mechanical seals, wear sleeves, precision bearings, semiconductor equipment, and high-temperature components.

Design considerations include brittleness, fracture toughness, thermal shock, minimum wall thickness, and machining requirements after sintering.

Buyers should specify ceramic composition, purity or grade, dimensions, tolerances, surface roughness, operating conditions, and quantity.

Quality control may include dimensional inspection, density measurement, material verification, and mechanical or electrical testing.
