Thermal conductivity of nanocomposites based on diamonds and nanodiamonds

Abstract The thermal conductivity of composites sintered from natural microdiamond (5–7 and 10–14 μm) and nanodiamond powders under pressure of ∼ 6.0 to 6.5 GPa at the temperature ∼ 1000 to 2000 °C for 6–20 s was measured in a steady heat flow in the temperature range of 50–200 °C. It was found that the thermal conductivity of nanodiamond composites produced in these conditions was less than 10 W/(m⁎К) while that of natural microdiamonds was as high as 500 W/(m⁎К).
