The temperature-stability relationships of the AlPO, polyrnorphs have been studied by X ray, thermal analysis, and thermal expansion. The system parallels that of silica very closely. Following is a diagrammatic representation of the findings for AlPO,: 1 0 2 2 -500 Berlinite (sl'* *+; Tridymite form + + Cristobalite form +>16000> Fused AIPOI 586' +2O 93' +3' 130°(?) 2100 =t50 ff-6 t , BI t , 81a+-+-@ Conversions from one form to another are shown to be much more rapid than for Furthermore, the temperatures, with the exception of the corresponding silica cases. berlinite inversion. are all lower than for corresponding silica temperatures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
