Aplicaciones

Barium hydroxide octahydrate has been used in the centromeric heterochromatin banding technnique and to synthesize BaTiO3. The form Barium hydroxide was reported to catalyze the rate of β elimination of phosphoserine residues. It is also used as a general purpose additive for lubricants and greases, sugar fabrication, manufacturing soaps, fat saponification and chemical synthesis of other barium compounds.

Notas

Air Sensitive. Store in cool dry place in tightly closed container. With good ventilation. Store away from air and oxidizing agent.
