WebApr 8, 2024 · The pressureless sintered composite ceramic containing 3 wt% h-BN obtained good properties, including a high thermal conductivity of 6.55 W/(m·K), a coefficient of thermal expansion of 4.47 ppm/K, a dielectric constant of 5.76 and a low dielectric loss of 7.02 × 10 −4 at 24 GHz. Compared to the pressureless sintered composite ceramics, the WebThermal conductivity is defined as the transportation of energy due to the random movement of molecules across the temperature gradient. In simple words, it is defined as the measure of a material’s ability to conduct heat. It is denoted by k. The inverse of thermal conductivity is thermal resistivity.
