ARTICLE ANNOTATION

quote
The article discusses the results of scientific research on the morphology and dimension of ultrafine tungsten powders by the crystal-optical method of sprinkling obtained by the plasma-chemical method using a PUV-300 hydrogen-plasma reduction unit. Analysis of the research results showed that the method for producing tungsten powders affects the shape and size, as well as the particle size distribution of the powders. The results of X-ray microanalysis show that in the production of the hard alloy from which the investigated roller for rolling metal was made, there were significant deviations from the manufacturing technology of such products. This is reflected in the fact that the composition of the micropowder of the hard alloy was heterogeneous. This is evidenced by the presence in the composition of the powder of such elements as sulfur, molybdenum, aluminum and calcium. These elements were included in the composition of the powder due to deficiencies in the enrichment of raw materials.
