The samples of non-sodium nickel hydroxycarbonate for nanosized catalysts have been obtained and investigated. The ratio of crystalline water, the amount of nickel hydroxide and carbonate has been calculated. By the X-ray analysis of obtained nickel oxide the crystallite size of 12–13 nm has been determined. The samples of catalysts provided a high specific surface.
Technological aspects of a new method of obtaining magnesium phosphate based on the interaction of magnesium chloride from liquid waste from the processing of potassium ores and sodium phosphate have been studied. The influence of precipitation conditions of magnesium phosphate crystal hydrate, washing of the obtained precipitate and its drying on the yield and product quality was studied. Rational technological parameters of realization of the main stages are chosen. The developed technological process, in comparison with the known
