| Description |
Single crystals of various types of diamonds have been grown by the melt solution crystallization at high pressures and temperatures. To define the emergences of dislocations onto the {100} and {111} faces, the selective etching of the crystals in KOH and KNO₃ melt has been used. It has been defined that the dislocation density, Nd, in diamond single crystals grown at a low growth rate of 1-2 mg/h at T = 1420-1500°C is 0.8-3·102 cm⁻² and the dislocation densities, Nd, in single crystals grown at temperatures 1280-1450°C and 1280-1350°C at growth rates of 3-5 mg/h and 20-25 mg/h are 1.1-2.2·103 and 1.06-1.35·106 cm⁻², respectively.
