Barium Molybdate properties

White or light green powder or lump. Relative density 4.65. Melting point 1480°C. Insoluble in water, slightly soluble in acids. Insoluble in water, slightly soluble in acids. Good adhesion to metals. Toxic!

Barium molybdate process

Complex decomposition method: Molybdenum concentrate is roasted by oxidation, and sodium molybdate solution is obtained by leaching with liquid alkali. Under stirring, barium chloride solution is added for reaction to produce barium molybdate precipitate, and the precipitate is separated by centrifugation, washed and dried to obtain finished barium molybdate.




Barium molybdate applications

Used as an adhesion agent for enamel products to make enamel adhere firmly to iron. Also used to remove sulfur from naphtha.

Barium Molybdate Safety

Packed in fiber drums lined with clean polyethylene plastic bags. The net weight of each drum is 40 kg, and care should be taken to prevent cracks in the mouth of the plastic bag. The package should be clearly marked "drugged". Store in a ventilated and dry warehouse. If the air is humid, the powder will absorb moisture easily and must be sieved. Tie the bag tightly or cover tightly after use to avoid sticking. It should not be stored and transported together with edible goods. When transporting, it should be protected from rain and sunlight exposure. When loading and unloading, it should be handled gently to prevent the package from being broken. In case of fire, use water, sand and various fire extinguishers to put out the fire. For toxicity and protection, see molybdenum trioxide.
