Abstract
Potassium zinc phosphate was synthesized by solid-state reaction using K3PO4·3H2O and ZnSO4·7H2O as reagents. To investigate the influence of molar ratio, grinding time, holding temperature, holding time on yield and zinc content of the product, experimental project was designed by uniform design and data mining technology. Obtained product was characterized by X-ray diffraction, scanning electron microscope and energy disperses spectroscopy. The results show that the two mathematical models can be established by regression analysis according to yield and zinc content, which can be used to obtain the best technology conditions of solid-state reaction. Under the optimum reaction conditions: molar ratio of K3PO4·3H2O: ZnSO4·7H2O = 1.01, grinding time 31min, holding temperature 750°C, holding time 3.2 h, the prepared product is KZnPO4with nano-lamellar structure, and the reaction average yield value is 84.33% and zinc content is 31.29%.
