Аннотация

In this article, scientific research on the production of thermophosphate fertilizers was carried out on the basis of thermo-alkaline activation of Central Kyzylkum waste phosphorite with mineralized mass and alkali metal salts, namely NaCl, KCl, Na 2 SO 4 , K 2 SO 4 , Na 2 CO 3 , K 2 CO 3 and silica at high temperature. In this case, samples are heated in muffle furnaces at temperatures of 800°C, 900°C, 1100°C, 1200°C and for 30 min, 60 min, 120 min. The total P 2 O 5 , assimilable P 2 O 5 , total СaO and total СO 2 forms of the sintered tablets were investigated. As it can be seen from the experiments conducted with mineralized mass phosphorite, alkaline salts and quartz sand, it was found that the assimilated form of СaO, P 2 O 5 and the degree of decarbonation rose with increasing temperature and time.
