美国GE公司合成的金刚石其品质可跟宝石相媲美,甚至它的一些独特的性能连天然金刚石也并不具备。在室温下这种合成金刚石是一种最有效的热导体,其导热系数还要比金刚石之冠——天然金刚石高50％,为普通铜导线的8.5倍。而且,合成金刚石晶体还能耐辐射损伤,即使用10倍于强功率激光器发射的光输出其激光辐射也不致于使晶体破裂。 The synthetic diamond produced by GE in the United States is comparable in quality to precious stones, and even some of its unique properties do not have natural diamond. This synthetic diamond is one of the most effective thermal conductors at room temperature with a thermal conductivity of 50% more than diamond crown, the natural diamond, 8.5 times the normal copper wire. Moreover, synthetic diamond crystals are also resistant to radiation damage, even when laser light is emitted at 10 times the intensity of the laser emitted by a high power laser and does not cause the crystal to crack.
