Abstract
This report presents a summary of data on the kinetic behavior of four proposed explosion inhibitor dusts--rock dust (calcium carbonate), purple-k (potassium bicarbonate), abc powder (monoammonium phosphate), and bcd powder (sodium chloride). All four materials were tested under conditions chosen to be similar to those that might be encountered in coal dust explosions. As expected, the principal products of rock dust decomposition are co2 and cao. Contrary to what is expected from literature data, the co2 is the only gaseous product observed during purple-k decomposition. It appears that the bcd powder did little more than vaporize. The abc powder gave a complex mixture of decomposition products. The strategy for later work on modeling the rate processes is outlined.
