Abstract
A pyrotechnic composition, particularly for fireworks, which contains an organic compound having at least one aromatic group as a binder. The compound preferably has a weight ratio of carbon:hydrogen of at least 10:1 and is substantially free of groups of the formulae COOH or COO.sup.-M.sup.+, wherein M.sup.+ is the equivalent of a metal ion. Also, pyrotechnic devices containing such composition.
Claims17
A solid, flowable, pyrotechnic composition, substantially free from elemental sulphur, comprising
- (a) an organic substance containing at least one aromatic group, containing carbon and hydrogen in a ratio of at least 10:1 by weight, and having a melting point of more than 150.degree. C., as a binder;
- (b) an oxidizing agent;
- and
- (c) a fuel.
A solid, flowable, pyrotechnic composition substantially free from elemental sulphur, comprising:
- (i) potassium perchlorate;
- (ii) potassium nitrate;
- (iii) potassium benzoate;
- and
- (v) 2-hydroxybiphenyl.
A solid, flowable, pyrotechnic composition substantially free from elemental sulphur, said composition comprising at least three components, one of those components being an organic substance containing at least one aromatic group, which substance contains carbon and hydrogen in a ratio of at least 10:1 by weight, has a melting point of not more that 150.degree. C., acts as a binder and is substantially free of groups of the formulae COOH and COO.sup.- M.sup.+, wherein M.sup.+ represents the equivalent of a metal ion.
