PROBLEM TO BE SOLVED: To improve an emission efficiency at a real use of a fire extinguishing agent for metal fire having boron oxide as its main component, which is effective for extinguish metal fire, by preventing its solidification and improving its fluidity even if it is stored in a emission container for a long period of time. SOLUTION: A hydrophobic silica, especially a highly hydrophobic silica subjected to a trimethylsilyl-group surface treatment, is added as a solidification inhibitor and a fluidity promoter to the main component, a boron oxide powder.
