<p>Fire suppressant compositions which are substantially free of ammonium nitrate and which comprise potassium nitrate in an amount sufficient to generate at least about 10 wt.% potassium carbonate when combusted. Most preferably, a guanidine salt, such as guanidine nitrate, is used in combination with the potassium nitrate. The compositions employed in the present invention have low pressure exponents, high burning rates and low flame temperatures.</p> |
