Flame Spray Pyrolysis Processing to Produce Metastable Phases of Metal Oxides

Abstract

Functional metal oxides can exist as different polymorphs. Meta stable phases of these oxides may be produced by flame spray pyrolysis (FSP). This is a scalable, rapid solidification process that may be used for nano powder synthesis. This review describes the key features of the FSP process and equipment. It also provides examples of the use of FSP process to obtain a meta stable oxide phases at RT which have unique properties.
