Abstract : MHF type fuels were examined for their tendency to explode when heated or burned. Heating the fuels (without burning) regularly produced explosions ranging from light to very strong. Only one burning test out of nearly one hundred resulted in an explosion. This was probably a detonation. Container materials, additives, and changes in the external environment had relatively little effect on the course of the burning. The temperature records showed that the nonburning fuels reached a temperature in the vicinity of 300C before exploding. Burning fuels, on the other hand, generally changed to auto-oxidation (flare burning) at temperatures between 100 and 200C and apparently were consumed before reaching the explosion temperature. The one burning test that resulted in an explosion appeared normal up to the moment of the explosion. No explanation is apparent for this test result. (Author)
