Essay

The object of study - powders of refractory nitrides, their interaction with biochemical and inorganic media. The goal of study - determination of mechanisms of powders in dependence on their structure and dispersity. The methods of study - analyses of powders concerming nitrogen content, XRD and SEM analyses, measurement of dzeta-potencial, EPR, method of polarization curves. The theoretical results and novelty - the scientifically based mechanism of powders dispersity effect on the rate of their interaction with media. The practical results and novelty - on base of determination of powder solubility in living organism media recommendations as for ecology of works with nitride powders in the plants of powder metallurgy. The degree of installation - the testing check of recommendations developed as for prevention of accidents at the working with powders (Act of installation of scientific results to KPMP, Brovary). The fields of using - powder metallurgy and ceramics.
