The paper analyzes ways to improve the quality index of the process of obtaining structural beryllium blanks by vacuum hot pressing of beryllium powders with a fineness of less than 56 microns. In the course of the work, the following were carried out: a comparative analysis of the quality of hot-pressed blanks depending on the production period; analysis of the representativeness of the values of the characteristics of powders; studied the dynamics of changes in the chemical composition of beryllium in the process of grinding ingots. The results of studies of the reasons for the instability of the quality of sintered beryllium billets are presented. Using the method of mathematical statistics, the influence of individual factors of industrial production on quality indicators was studied. The results of changes in the chemical composition of beryllium during the grinding of ingots are presented, as well as an assessment of the irreproducibility of the results of analysis of the content of impurities and certification of products by mechanical properties.
