Hexanitrodiphenylamine (abbreviated HND), is an explosive chemical compound with the formula C12H5N7O12. HND was used extensively by the Japanese during World War II but was discontinued due to its toxicity.
HND is a booster-class explosive that was used in World War II by the Germans as a component of Hexanite (60% TNT - 40% HND) and by the Japanese as a component of Kongo (Type 98 H2) (60% Trinitroanisol - 40% HND) for use in bombs, sea mines and depth charges; Seigate (Type 97 H) (60% TNT - 40% HND) for use in torpedo warheads and depth charges; and also in Otsu-B (60% TNT, 24% HND & 16% aluminium powder) for use in torpedo warheads.
Safety and toxicity
A most toxic and poisonous explosive, it attacks the skin, causing blisters which resemble burns. Dust from HND is injurious to the mucous membranes of the mouth, nose, and lungs.
