Strontium chlorate


Strontium chlorate is a chemical compound with the formula Sr(ClO3)2. It is a strong oxidizing agent. It exists in several hydrated forms; the monohydrate (Sr(ClO3)2·H2O), the trihydrate (Sr(ClO3)2·3H2O), and the octahydrate (Sr(ClO3)2·8H2O) It has been used as an oxidizing agent in explosive mixtures, where it has a cooling effect because of the large amount of water of crystallization. It has also been used in a published Italian pyrotechnic violet star formula Wikipedia
