Abstract
Un mélange homogène particulaire de pyrophosphates et tripolyphosphates de métaux alcalins est préparé en évaporant à siccité une solution aqueuse d'orthophosphates de métaux alcalins dont le rapport molaire des métaux alcalins au phosphore est de 5:3 à 6:3 et en calcinant les particules séchées résultantes. De préférence, le métal alcalin est le sodium et la composition de la solution est ajustée pour que le produit final contienne beaucoup de pyrophosphate de sodium et peu de tripolyphosphate de sodium.
