A white crystalline powder that readily absorbs Carbon dioxide from the air to convert to the insoluble Barium carbonate. Barium hydroxide has been used for both aqueous and nonaqueous neutralization/alkalization of paper (AIC Book and Paper catalog) where the deposition of barium carbonate provides an alkaline reserve. Barium hydroxide is used in the manufacture of glass and ceramic glazes as well as for corrosion inhibition and the removal of sulfates in water. It is also used as a rodenticide, Insecticide, and fungicide.
