摘要

27,005. Wetter, J., [Westfõlisch-Anhaltische Sprengstoff Akt.-Ges.]. Dec. 10. Explosives.-In priming-compositions for percussion caps, a chromate, preferably of lead or mercury, is employed as an oxygen-carrier, to avoid the rusting of gun barrels. The chromate may be admixed with a metallic oxide or peroxide. Examples quoted contain (a) 36 parts of fulminate of mercury, 40 parts of chromate of lead or mercury, 20 parts of antimony sulphide, and 4 parts of pulverized glass, and (b) 40 parts of fulminate, 16 parts of either potassium chlorate or lead peroxide, 20 parts of lead chromate, and 6 parts of pulverized glass.
