| Abstract: | Tabular gem-grade diamond crystal is of very applicable value. It can be used as transparent window for infrared ray and heat dispersion plate for high power laser weapon etc.. The correlation of gem-grade diamond synthesized by temperature gradient method with the growing face of seed crystal and synthesizing temperature was studied in the paper. Superior tabular crystal of 4mm in diameter was synthesized with { 100 } face of seed crystal in lower temperature area. |
