Abstract
The possibility of foaming of phosphate glass matrices for the synthesis of complex micronutrient fertilizers with prolonged action is considered. The region of glass formation in the K2O–CaO–P2O5 system has been studied. The optimal composition of the initial glass is selected. Foaming of the initial mixtures is carried out using one-stage and two-stage technology; their internal structure, phase composition, and resistance to water are studied. It has been established that foaming using the two-stage technology makes it possible to obtain a material with stable structure and properties, which is important when it is used as a fertilizer with prolonged action.

复杂微肥用磷酸盐玻璃基体的合成与发泡
摘要
考虑了磷酸盐玻璃基质发泡以合成具有延长作用的复杂微量营养肥料的可能性。研究了K 2 O–CaO–P 2 O 5系统中玻璃的形成区域。选择初始玻璃的最佳成分。使用一阶段和两阶段技术对初始混合物进行发泡。研究了它们的内部结构,相组成和耐水性。已经确定的是,使用两阶段技术的发泡使得可以获得具有稳定的结构和性能的材料,这在用作具有长效作用的肥料时是重要的。
