HEAT-RESISTANT IGNITER COMPOSITIONS FOR ELECTRIC SPARK IGNITERS AND METHOD OF MANUFACTURING THEREOF Russian patent published in 2002 - IPC

FIELD: manufacture of initiation means, more particularly pyrotechnic compositions for electric primers. SUBSTANCE: first heat-resistant igniter composition comprises lead rhodonite, potassium perchlorate and lead chromate. Second composition comprises potassium perchlorate and potassium picrate. Method of preparing said compositions comprises chemical codeposition in aqueous solutions of components in one stage. Invention makes it possible to prepare heat-resistant igniter composition for electric spark igniters having low characteristics of safety minimum current, minimum operate current and method of preparation thereof. EFFECT: improved properties of igniter compositions. 3 cl, 2 tbl
