Abstract
The present invention is directed to a lead-free, nontoxic pyrotechnic composition, comprising: 30-80 wt % of bismuth subnitrate; and 10-50 wt % of a fuel, wherein all weight percents are based on the total weight of the composition. The present invention is also directed to a lead-free, nontoxic priming composition, comprising: 20-80 wt % of the above nontoxic pyrotechnic composition; 20-50 wt % of an initiator explosive; and 2-10 wt % of a sensitizer, wherein all weight percents are based on the total weight of the composition.
Claims19
A lead-free, nontoxic priming composition, comprising:
- 20-80 wt % of a nontoxic pyrotechnic composition comprising (a) 30-80 wt % of bismuth subnitrate and (b) 10-50 wt % of a fuel;
- 20-50 wt % of an initiator explosive;
- and
- 2-10 wt % of a sensitizer;
- wherein all weight percents are based on the total weight of said composition, and wherein said composition is substantially lead-free and substantially nontoxic.
