Application of thermal gas analysis to investigation of SrO interaction with NH4H2PO4

The so-called technique of effective anion is suggested to investigate varitions of cation composition and of anion distribution centre in the melt of nonvolatile products of reaction between NH4H2PO4 and M2O depending on temperature. Thermal gasoanalytical facility, which allows to conduct continuous recording of NH3 and H2O release during reaction under the conditions of nonisothermal heating in inert atmosphere, is described. Experimental potentialities of the facility and of effective anion technique are tried using NH4H2PO4 specimen and are used to study thermal interaction SrO with NH4H2PO4 at ≥75 mol. % phosphate content
