| Abstract: | HOTDISK is widely used in thermal conductivity measurements of engineering materials. A series of homogeneous materials with a low thermal conductivity, such as aerogel powder, insulation blanket and insulation board, are measured with HOTDISK. Measuremet results at different times are compared with each other, compounding cautions and advises based on data varied with time are given. |
