moglich, iiber die Existenz zweier neuer Modifikationen zu berichten und deren Strukturen zu beschreiben. Die eine ist hexagonal vom Typ des CeP04. t H20, die andere eine monokline Hochtemperaturform, die sich bei gewohnlicher Tem-peratur sehr langsam in den Monazit-Typ umwandelt. Die hexagonale Struktur wurde aus vVeissenberg-Aufnahmen, die Hochtemperatur-Struktur aus Pulver-aufnahmen bestimmt. Die drei Strukturen haben gemeinsame Ziige und ein Vergleich scheint anzudeuten, daB die Transformation eher displaciver als dis-ruptiver Art ist. Bismuth phosphate has long been known to crystallize with the monazite-type structure. It is now possible to report the existence of two other modifi-cations, and to describe their crystal structure. One ...
