2 results about "Ferric Pyrophosphate" patented technology

This invention discloses a hydrothermal preparation process for sodium ferric pyrophosphate, comprising the following steps: S1, preparation of precursor mixed solution: weigh sodium source, iron source, phosphorus source, and pyrophosphate source according to stoichiometric ratio, add complexing agent and pH buffer, and stir evenly to obtain precursor mixed solution A; S2, complexation and stabilization treatment of pyrophosphate: add complexing agent B to precursor mixed solution A to form a stable pyrophosphate complex, obtaining precursor solution B; S3, hydrothermal reaction: after hydrothermal reaction, naturally cool to obtain hydrothermal product; S4, post-treatment: centrifuge, wash, and dry the hydrothermal product to obtain sodium ferric pyrophosphate precursor powder; S5, carbon coating and calcination: calcine the sodium ferric pyrophosphate precursor powder and carbon source at wet high temperature to obtain carbon-coated sodium ferric pyrophosphate material. This invention features high crystallinity, high compaction density, strong process feasibility, and excellent comprehensive performance.
