Abstract
A method for the manufacture of primers/detonators with 90-99.99% reliability and achieving sensitivity of 0.8 inch-oz to 3.0 inch-oz, able to withstand temperatures within the range of 40.degree. C. to 200.degree. C. and able to withstand temperature cycling and humidity for 95% RH at 95.degree. C. to -40.degree. C. Mechanical and chemical sensitizers are utilized in lieu of tetracene, the utilization of oxidizers as sensitizers, the utilization of high energy fuels, and a method of co-precipitating the primary explosive and mechanical sensitizer.
Claims1
A consolidated mixture of a primer initiating composition omitting tetrazene as a sensitizer yet capable of withstanding aging and providing a relatively high degree of sensitivity, reliability, and confidence level within a wide temperature range consisting essentially of:
- from 40 to 42 weight percent of basic lead styphnate;
- from 20 to 22 weight percent of lead azide;
- from 15 to 20 weight of barium nitrate;
- and
- from 1 to 3 weight percent of a sensitizer selected from the group consisting of silicon carbide, fused alumina, ground glass powder, and pure silica sand.
