LFA 1000 – Carbide Ceramics – Thermal Conductivity

Carbide ceramics exhibit exceptional thermal conductivity and resilience against abrasion, corrosion, and high temperatures. Through the strategic combination of different carbides, it becomes possible to tailor the material’s properties to diverse applications, achieving specific characteristics such as defined electrical conductivity or high hardness. The application fields of carbide ceramics span mechanical, chemical, space, and power engineering.

App. Nr. 02-007-006 LFA 1000 – Carbide Ceramics – Thermal Conductivity

To precisely determine the thermal conductivity of three distinct carbides, a Laser Flash Analysis (LFA) was conducted. The uranium derivative (UC) demonstrated a notably low thermal conductivity, hovering around 25 W/mK, and maintaining relative constancy across the temperature range. Zirconium carbide (ZrC) exhibited an increasing trend in thermal conductivity, while silicon carbide (SiC) displayed a decreasing trend that tends toward a constant value at higher temperatures. This variation in thermal conductivity among different carbides provides insights into their thermal performance and underscores the versatility of carbide ceramics in meeting specific engineering requirements across a spectrum of industries.
