초록

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.
