Abstract
A method is disclosed of making yttrium silicon oxy compounds, comprising: (a) mixing powdered hydrated metal nitrate with silica in molar equivalent amounts to yield upon heating a desired duo metal oxy compound; (b) agitatingly heating said mixture to melt and decomposition temperatures for the nitrate (e.g., 340.degree.-370.degree. C.), the melt encapsulating the silica particles; and (c) heating the sludge to a temperature (1300.degree.-1550.degree. C.) for a period of time (2-5 hours) effective to stimulate chemical reaction between the decomposed nitrate and silica to form yttrium silicon oxide.
