Alumina Ceramics Thermal Conductivity: A Complete Guide
2026-09-24The thermal conductivity of alumina ceramics is typically around 20–30 W/(m·K) at room temperature (approximately 25°C). However, the actual value varies depending on purity, microstructure, and temperature. High-purity alumina (99% or higher) has a thermal conductivity of approximately 30 W/(m·K) at room temperature, which is superior to that of ordinary ceramics but lower than that of metals; for lower-purity alumina (90%–95%), this value drops to 15–20 W/(m·K).
