摘要：
An improved method for the direct measurement of the bulk thermal conductivity of super-hard materials in a stationary regime is described. The method is based on a technique known as the 'squeezing' of the heat flux at the flat specimen-cone-shaped indentor interface. Results of thermal conductivity measurements of natural and synthetic diamonds, CVD diamond films, and AlN ceramics are presented. The uncertainty of the measurement method is discussed.
