关于金刚石气相合成法,已经发表了热灯丝方法以及其他许多的研究报告,不过,笔者认为这些方法跟现在已应用很广的高压法比较,其合成速度慢,在实际应用中还留有研究的余地。 在这种情况下,东京工业大学的吉川昌范研究室和本公司共同研究了利用弧光放电等离 There have been published hot filament methods and many other research reports on the diamond vapor phase synthesis method. However, in the author’s opinion, these methods are relatively slow to synthesize and have been studied in practical applications room. In this case, Yoshikawa Masanobu Laboratory of Tokyo Institute of Technology and our company jointly studied the use of arc discharge plasma
