WebDiamonds are discovered at a depth of around 150-200 kilometers below the surface. And the temperatures range from 900 to 1,300 degrees Celsius, with pressure ranging from 45 to 60 kilobars (about 50,000 times that of air pressure at the Earth’s surface). WebMay 11, 2024 · The thermal conductivity of IIa diamond from low temperature (80 K) to room temperature was studied by laser-excited Raman spectroscopy. The laser has two complementary effects, one performing the Raman spectrum and the other resulting in the local heating on the surface of diamond.
WebApr 3, 2001 · Diamond is the hardest material known to man. It also has other properties that make it a useful engineering material such as a low co-efficient of friction and high thermal conductivity. As such it is used in cutting tools, heat sinks, semiconductors, optical components etc. WebThe specific heat of diamond at 500° is about 0.4 cal./g. °C. and this decreases to only 0.0025 cal./g. °C. at 90° K. The average specific heat over this temperature range is about 0.23 cal./g. °C. and the sensible heat is, therefore, 160 cal. per gram. This is about 105 times greater than the heat of adsorption.
