STUDIES ON EXPLOSIVE ANTIMONY: IV. THE HEAT OF EXPLOSION AT 40 °C.

Abstract

The heat of the "explosive" crystallization of electrolytically deposited amorphous antimony has been directly determined at 40 °C. in a modified Bunsen-type calorimeter using benzalacetone as the working substance. Correction was made for the amount of antimony trichloride in the deposits and for the crystallization that had taken place between their preparation and explosion. Sixteen runs on exceptionally uniform specimens containing between 4.0 and 7.9% antimony trichloride gave 21.8 cal. per gm. for the heat of explosion, which thus appears to be independent of the antimony trichloride content.
