    Description / Table of Contents: Formation and Thermal Transformations of Polymeric Potassium Lead Phosphates in the System KPO3—Pb(PO3)2The polyphosphate [K2Pb(PO3)4]x and the cyclotriphosphate K4Pb[P3O9]2 existing in the system KPO3—Pb(PO3)2 are stable up to their melting points. The formation, melting and crystallization reactions of both compounds are described.

    Description / Table of Contents: Phase Equilibrium Diagram of the System KPO3—Pb(PO3)2The phase equilibrium diagram of the system KPO3—Pb(PO3)2 was determined by means of X-ray, DTA, paper chromatographic and hot-stage microscopic investigations. In addition to the polyphosphates of potassium [KPO3]x and lead [Pb(PO3)2]x it is shown the existence of only two thermodynamically stable potassium lead phosphates: The incongruently melting cyclotriphosphate K4Pb[P3O9]2 and the congruently melting high-molecular polyphosphate [K2Pb(PO3)4]x. The preparation of the cyclotetraphosphate K2Pb[P4O12] in the pure state, obtainable by precipitation from aqueous solution, is not possible by means of thermal interaction of any starting materials.
    Notes: Die mit Hilfe von papierchromatographischen, röntgenographischen, differentialthermographischen und heizmikroskopischen Untersuchungen durchgeführte Bestimmung des Zustandsdiagramms des Systems KPO3—Pb(PO3)2 führt zu der Schlußfolgerung, daß in diesem System außer den beiden Polyphosphaten [KPO3]x und [Pb(PO3)2]x nur zwei thermodynamisch stabile Kalium-Blei-Phosphate existieren: das inkongruent schmelzende Cyclotriphosphat K4Pb[P3O9]2 und das kongruent schmelzende hochmolekulare Polyphosphat [K2Pb(PO3)4]x. Ein durch Fällung aus wäßriger Lösung erhältliches Cyclotetraphosphat K2Pb[P4O12] läßt sich auf thermischem Wege nicht in reiner Form herstellen.
