PURPOSE:To manufacture a superhigh pressure stable phase substance of quality at a low cost by non oxide ceramics such as cubic system boron nitride and diamond. CONSTITUTION:A target contg. atoms capable of forming a superhigh pressure stable phase substance (in the case of cBN, B and N are used, and in the case of diamond, C is used) is set in liquid nitrogen, and the above target is irradiated with laser beams hard to absorb energy by liquid nitrogen by condensing light by condenser lens, by which the objective substance is formed, and simultaneously, powder and/or particles are released from the target and are recovered. |
