Diamond can be applied in high technology and future industry areas due to its high hardness, high thermal conductivity, ultrawide band optical transmission range and excellent semiconducting characteristics. Specially, the high thermal conductivity of diamond is its most attractive property, since it can be used as a heat sink in high-power semiconductor devices and medium-wave oscillators.
