Abstract

The enthalpy of oxygen dissolution in liquid zirconium occurring during the combustion of Zr particles is estimated. The analysis presented uses direct experimental measurements of the temperature, size, and composition histories of burning Zr particles. The dissolution enthalpy is limited by the range of 700–830 kJ/mol and is somewhat less than that of Zr oxidation. This enthalpy determines the rate of the heat release during Zr combustion until stoichiometric ZrO2 forms out of the supersaturated Zr/O solution. Stoichiometric ZrO2 is formed near the end of combustion and the additional energy released at that time causes a rapid temperature increase which can trigger a particle explosion.
