文摘

The thermokinetic data on the process of oxidation, of NH4VO3 + HOCH2CH2OH modified ASD-4 powder have been obtained by the TG and DSC methods during heating in air up to 1473 K at a rate of 10 K / min. The process of phase formation was studied directly during oxidation of the modified ASD-4 powder under similar conditions by the X-ray diffraction method using a synchrotron radiation from the VEPP-3 station of Channel 4 on the basis of equipment available at ISSCM SB RAS. It was found that oxidation of the activated powders is shifted into the low temperature region. Two modifiers: NH4VO3 + HOCH2CH2OH and previously examined V2O5 nH2O were compared.
