Gewinnung und Darstellung
Kaliumdiphosphat kann durch Dehydration von Dikaliumhydrogenphosphat bei 350 β 400 Β°C gewonnen werden.cite-ref-arthur-d-f-toy-4-0[4]

Ebenfalls mΓΆglich ist die Gewinnung durch Reaktion von Kaliumcarbonat mit Phosphorpentoxid.cite-ref-govindhan-dhanaraj-kullaiah-byrappa-vishwanath-prasad-michael-dudley-5-0[5]

Eigenschaften
Verwendung
Kaliumdiphosphat wird in Textilhilfsmitteln zur VerhΓΌtung von HΓ€rte-NiederschlΓ€gen, als Seifenzusatz, zur kathodischen Abscheidung von Zinn oder Zinn-Gold-Legierungen, zur Wasserstoffperoxid-Stabilisierung, zur Tonreinigung und bei ErdΓΆlbohrungen verwendet.cite-ref-r-mpponline-3-1[3]
