Barium chlorate is white crystals.
01 · Identification
What Barium chlorate is
Barium chlorate is white crystals. It melts at 414 °C, is slightly soluble in water.
Under the GHS it carries the signal word Danger. It is classed as reactive agents - 1st degree.

04 · Handling and storage
Storing and handling Barium chlorate
Storage conditions
Separate from acids, alkalies, reducing agents, combustibles, ammonium compounds. Store in a cool, dry, well-ventilated location.

Incompatible materials
A strong oxidizer. Barium chlorate is a reactive chemical and is an explosion hazard. Violent reaction may occur with reducing materials, strong acids, powdered metals. Combustible materials will increase activity in fire.

Reactivity
BARIUM CHLORATE is an oxidizing agent. Liberates explosive chlorine dioxide gas in the presence of a strong acid. Heating a moist metal chlorate and a dibasic organic acid liberates chlorine dioxide and carbon dioxide [Bretherick 1979 p. 100]. Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination, in finely divided form with finely divided aluminum can explode by heat, percussion, or friction [Mellor 2:310 1946-4].
