Abstract

Conducted comparative analysis of properties of powders of Cu—S and Cu—P alloys got the stove synthesis with the use of initial copper powder of brand ПМС-1. Certain chemical composition, microhardness and compactibility of powders. It is shown that the synthesized powders of Cu—S alloy have more stable chemical composition than powders of Cu—P alloy. Microhardness of powder of Cu—S alloy (1,364 ± 0,235 GPа) within the limits of error answers the microhardness of Chalcocite (Cu₂S), and microhardness of powder of Cu—Р alloy approximately on 30% less than than micro-hardness of copper phosphide (Cu₃P) and presents 2,162 ± 0,284 GPа. A most compression, at the equal terms of pressing has powder of Cu—S alloy.
