Description and Uses

Potassium chlorate, is a transparent, colorless crystal or white powder. It is soluble in boiling water and decomposes at approximately 750°F (398°C), giving off oxygen gas. Potassium chlorate is a strong oxidizer and forms explosive mixtures with combustible materials, such as sugar, sulfur, and others. Potassium chlorate is incompatible with sulfuric acid, other acids, and organic material. The four-digit UN identification number is 1485. Its primary uses are as an oxidizing agent in the manufacture of explosives and matches; in pyrotechnics; and as a source of oxygen. Sodium and potassium chlorates have similar properties. Chlorites are powerful oxidizing agents. They have one less oxygen than the base-state oxysalts. They form explosive mixtures with combustible materials, and in contact with strong acids, they can release explosive chlorine dioxide gas.

Potassium Chlorate is used in micro-smoke cold fireworks containing bright bead.
