Abstract (en)
[origin: EP3659992A1] The present invention relates to a metallic mixture blasting capsule comprising: an outer cylinder; an inner cylinder accommodated inside the outer cylinder; a rapidly expanding metallic mixture composed of a sodium nitrate powder which is an oxidizing agent, a ferric oxide powder which is an oxidizing agent, an aluminum powder which is a reducing agent, a solid lubricant powder which is an anti-friction agent between powders, and an inorganic filler powder which is a filler for pores between powders, and is filled between the outer cylinder and the inner cylinder; a rapidly detonating metallic mixture composed of a sodium nitrate powder which is an oxidizing agent, a ferric oxide powder which is an oxidizing agent, a copper oxide powder which is an oxidizing agent, an aluminum powder which is a reducing agent, and a magnesium powder which is a reducing agent, and is mixed in a weight ratio greater than that of the aluminum powder and filled in the inner cylinder; and an electric spark generation means embedded in the rapidly detonating metallic mixture.
