Abstract: Diamond crystals are produced by subjecting to elevated temperatures and pressures a mixture of a nondiamond form of carbon together with a mixture or alloy of cobalt and phosphorus, which serves as the solvent and catalyst for the conversion to diamond form. Use of cobalt and phosphorus for solvent and catalyst allows conversion of nondiamond carbon to diamond at lower pressures than previously utilized, i.e., from about 42,200 to about 49,000 atmospheres.
