Effects of Temperature and Aging on Emulsified Liquid Oxidizing Solutions Containing More Than 70 Percent Ammonium Nitrate Solutions with More Than 0.4 Percent Combustible Substances

The shock and thermal sensitivity of three different emulsified liquid oxidizing solutions was examined using tests selected from the United Nations 'Manual of Tests and Criteria'. The solutions are used as raw materials in the manufacture of explosive blasting agents and were tested in the 'as received' condition at ambient and elevated temperatures (150 deg F); tests were also conducted on samples aged for 30 and 60 days. None of the samples exhibited any marked sensitivity to explosive shock. However, there was some indication of thermal sensitivity in heavily confined samples exposed to the action of 20 and 10 g black powder igniters. None of the samples exhibited any significant increase in sensitivity when tested at elevated temperatures or after aging. Plans are being made to test additional samples.
