Barium Molybdate

Barium molybdate is a chemical compound with the formula BaMoO4. It is a white crystalline solid that is insoluble in water and organic solvents but soluble in acids.

Barium molybdate has a tetragonal crystal structure with space group I41/a and lattice parameters a = 5.116 Å and c = 11.993 Å. The barium ions are coordinated by eight oxygen atoms in a distorted cube, while the molybdate ions are tetrahedrally coordinated by oxygen atoms.

Barium molybdate is commonly used as a pigment in ceramics, paints, and coatings due to its high refractive index and low solubility. It also exhibits photocatalytic activity and has been studied for use in water purification and hydrogen production.

In terms of safety, barium molybdate is considered relatively non-toxic when ingested or inhaled in small quantities. However, prolonged exposure to high levels may cause respiratory and gastrointestinal irritation. It is important to handle this compound with care and follow proper safety protocols when working with it.
