Diamond electric conductivity
WebDec 25, 2024 · Electricity – For the best and most reliable diamond tester, find a device that utilizes electricity. These testers function in a similar way to heat testers but provide a more accurate analysis. Somewhat unsurprisingly, they do have a higher price tag attached. However, they can detect moissanite, unlike the diamond heat testers mentioned above. WebNov 12, 2024 · Its thermal conductivity is insanely high in the x-y plane (about 4 times that of copper). But in the z direction, the thermal conductivity is very low, about 2 orders of magnitude less than copper. Something similar happens with its electrical conductivity. therefore thermal conductivity is directly proportional to electrical conductivity. Not ...
