  2. Material properties of diamond - Wikipedia

    en.wikipedia.org/wiki/Material_properties_of_diamond

    Thermal conductivity of natural diamond was measured to be about 2,200 W/(m·K), which is five times more than silver, the most thermally conductive metal. Monocrystalline synthetic diamond enriched to 99.9% the isotope 12 C had the highest thermal conductivity of any known solid at room temperature: 3,320 W/(m·K), though reports exist of ...

  3. Thermal conductivity and resistivity - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductivity_and...

    The thermal conductivity of natural diamond at room temperature is several times higher than that of a highly conductive metal such as copper (although the precise value varies depending on the diamond type). [19] Thermal conductivities of selected substances are tabulated below; an expanded list can be found in the list of thermal ...

  4. List of thermal conductivities - Wikipedia

    en.wikipedia.org/wiki/List_of_thermal_conductivities

    Very high thermal conductivity measurements up to 22,600 w m −1 K −1 were reported by Fenton, E.W., Rogers, J.S. and Woods, S.D. in reference 570 on page 1458, 41, 2026–33, 1963. The data is listed on pages 6 through 8 and graphed on page 1 where Fenton and company are on curves 63 and 64.

  5. Isotopically pure diamond - Wikipedia

    en.wikipedia.org/wiki/Isotopically_pure_diamond

    The 12 C isotopically pure, (or in practice 15-fold enrichment of isotopic number, 12 over 13 for carbon) diamond gives a 50% higher thermal conductivity than the already high value of 900-2000 W/(m·K) for a normal diamond, which contains the natural isotopic mixture of 98.9% 12 C and 1.1% 13 C.

  6. Thermal conductivity measurement - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductivity...

    A thermal conductance tester, one of the instruments of gemology, determines if gems are genuine diamonds using diamond's uniquely high thermal conductivity. For an example, see Measuring Instrument of Heat Conductivity of ITP-MG4 "Zond" (Russia).

  7. Synthetic diamond - Wikipedia

    en.wikipedia.org/wiki/Synthetic_diamond

    The thermal conductivity of pure diamond is the highest of any known solid. Single crystals of synthetic diamond enriched in 12 C (99.9%), isotopically pure diamond, have the highest thermal conductivity of any material, 30 W/cm·K at room temperature, 7.5 times higher than that of copper. Natural diamond's conductivity is reduced by 1.1% by ...

  8. Superhard material - Wikipedia

    en.wikipedia.org/wiki/Superhard_material

    Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material. However, diamond has several limitations for mass industrial ...

  9. Thermal conductance and resistance - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductance_and...

    A 2008 review paper written by Philips researcher Clemens J. M. Lasance notes that: "Although there is an analogy between heat flow by conduction (Fourier's law) and the flow of an electric current (Ohm’s law), the corresponding physical properties of thermal conductivity and electrical conductivity conspire to make the behavior of heat flow ...
