AbstractThe diamond particles with five micrometers in diameter are synthesized in ten seconds with conventional spark apparatus. The method was originally designed for non-conductive sample pre-treatment for SEM analysis. With these spark apparatus, specimens were coated with carbon fine particles in around ten seconds, and surfaces were kept in low temperature. But carbon fine particles were spread over all directions. The apparatus was specially modified for this study such as tubing for hydrogen gas introduction, with specially designed top shaped rod with prepared ultra-high purity of graphite. It was confirmed that diamond particles were synthesized on silicon wafers, Al2O3 ceramics and non-alkaline glass. Future possibility for install in airplane for parabolic flight will be discussed in the meeting.
