METHOD FOR DETERMINING FREE RADICALS IN HIGH-TEMPERATURE OXIDE MELT

WIPO Patent Application WO/2022/121194

A1

A method for determining free radicals in a high-temperature oxide melt, comprising: firstly, equally dividing an oxide powder to be determined into two parts by mass, respectively placing same in two identical corundum crucibles having a polygon cross section and tamping same, placing both the corundum crucibles in a high-temperature furnace, then increasing the temperature to 1600℃ or more, and respectively maintaining the temperature for different times and then quenching; and measuring the relative average height difference of the oxide melt that has been maintained for different times at each corner of the corundum crucible, when a height difference exists, it indicates that the oxide produces free radicals during the high-temperature process, and a larger height difference indicates that the oxide melt produces more free radicals during the high-temperature process. The method can determine free radicals in a high-temperature oxide melt, and has the characteristics of a simple process and easy operation.
