Webwe computed the specific heat of UNCD as a function of temperature from the vibrational spectra. We find that the specific heat of UNCD shows enhancements of approximately 20% over that of single-crystal diamond at 300 K. The excess specific heat in UNCD in comparison to single-crystal diamond is found to be maximum at approximately 350 K. 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.
