Abstract
A priming mixture containing no toxic materials, in particular no Pb, Ba or Sb compounds, and presenting at least one primary explosive, an oxidizing agent, a reducing agent, and an inert friction agent; the oxidizing agent consisting essentially of stannic oxide, SnO.sub.2. The central-fire or rimfire percussion primer presents a casing containing the priming mixture, and, in the case of the central-fire primer, also an anvil.
Claims17
A priming mixture containing no toxic metal containing compounds, including no Pb, Ba, Sb compounds, and comprising at least one primary explosive;
- an oxidizing agent;
- and at least one reducing agent;
- wherein said oxidizing agent consists essentially of stannic oxide SNO.sub.2.
In a mixture for priming a percussion charge wherein a primary explosive that is sensitive to shock and heat and provides a high flame propagation rate is present in admixture with an oxidizing agent and a reducing agent, said primary explosive, oxidizing agent and reducing agent being present in the mixture in respective amounts such that the mixture is effective for priming the percussion charge, the improvement wherein the oxidizing agent consists essentially of stannic oxide and the mixture is free of compounds containing Pb, Ba, or Sb.
