| Abstract: | A study is carried out of the stability of a liquid-form zinc-boron system water-soluble fertilizer, and an investigation of the effect of the reactant proportioning, pH, temperature and static storage time on the stability of the system. The experimental results show that when the borax content increases to a certain extent, precipitation appears in the system, and precipitation increases with the increase in the pH. At pH ≤5 the precipitate is H3BO3, at pH =6, Zn（OH）2 and Zn（HSO4）2 settle down. At pH = 3, norml temperature or 50℃ chemical reaction occurs on standing to give waterinsoluble ZnB3O3（OH）5]·H2O, but after a certain time the system is able to reach a stable state. |
