日本富士通研究所最近开发了一种人工合成金刚石薄膜的新方法——金刚石射流法。金刚石除了作宝石外,也是非常优良的工业用材料,它具有如下特点:①在所有的物质中硬度最大;②在所有的物质中导热性最好(是铜的2倍以上);③是高性能的半导体材料(可在500℃以上使用);④折射率高,紫外线透过性能好;⑤声波传播快等。由于它具有上述优点,所以人们希望能够廉价而大量地得到金刚石,但是以往工业上合成金刚石,一
Japan Fujitsu Institute recently developed a new method of synthetic diamond film - diamond jet method. In addition to diamond as a precious stone, but also a very good industrial materials, it has the following characteristics: ① the hardness of all substances in the most; ② the best thermal conductivity of all substances (more than 2 times the copper); ③ is high Performance of semiconductor materials (which can be used above 500 ℃); ④ high refractive index, good UV transmission performance; ⑤ sound wave propagation fast. Since it has the above advantages, it is hoped that diamonds can be obtained cheaply and in large quantities, but in the past, synthetic diamond
