Abstract

PURPOSE:To synthesize diamond powder efficiently at comparatively low pressure by a method wherein a mixture of graphite fluoride powder and copper (or iron) powder is pressurized and molded and pressurized by impulse waves. CONSTITUTION:Copper (or iron) with not more than approximate 200mu grain size, which weight % is the not less than approximate 80 weight % of graphite fluoride with not more than approximate 100mu grain size, is mixed to the graphite fluoride (it is preferable that carbon and fluorine are equivalent mol or fluorine is slightly excessive), and molded, and dust bodies with not more than approximate 30% porosity are manufactured. Impulse waves with approximate 400-1500K bar are applied to the said dust bodies, the dust bodies are treated near the boiling point of sodium chlorate by using conc. nitric acid to which a small quantity of sodium chlorate is mixed, and carbon under a non-transition condition is dissolved and removed, thus obtaining diamond powder.
