Outline of Final Research Achievements

The objectives of this study were to directly compare the flame inhibition efficiency of transition metals using metallocenes and to develop a novel ferrocene-containing fire suppressant: an aqueous ferrocene dispersion. In this study, the downward flame spread rates over filter paper samples on which each metallocene was adsorbed were determined; besides, TG measurements were conducted to finally determine the phase in which each metallocene produced its flame inhibition effect. Aside from the experiments, for aqueous ferrocene dispersions, the dispersibilities and suppression capabilities to suppress pool fires were investigated. The former experiment indicated that the metallocenes tested in this study exhibit a flame inhibition effect solely in the gas phase. The latter experiment demonstrated that there is a positive relationship between their suppression capabilities and the dispersions and that aqueous ferrocene dispersions have shorter extinguishing times than a wet chemical.
