Uses and synthesis of Molybdenum trioxide powder

Molybdenum trioxide powder, also known as molybdenum anhydride, has a molecular weight of 143.94. White transparent rhombic crystal, with a light green color, turns yellow when heated, and returns to its original color when cooled. Insoluble in water, it can be melted in ammonia water and strong alkali solution to produce molybdate. Molybdenum trioxide is used primarily to produce molybdenum and catalyzes many organic reactions, such as propylene ammoxidation to acrylonitrile. Molybdenum trioxide can be used as analytical reagent to produce raw material of molybdenum metal, molybdenum alloy and molybdenum salt. Used as a catalyst in the petroleum industry; Used for enamel glaze pigment and medicine.

Applications/Functions of Molybdenum trioxide powder

1. Molybdenum trioxide powder is used for the determination of blood glucose, protein, alkaloid, arsenic and phenol as a spectral analysis reagent.
2. Molybdenum trioxide used as a raw material for producing molybdenum metal and molybdenum compounds. Used as a catalyst in the petroleum industry. It can also be used for enamel glaze pigment and medicine.
3. Metallurgical industry used as powder metallurgy raw materials, the production of various molybdenum metal materials, chemical industry used as a variety of molybdenum compound molybdenum source additives, molybdenum catalyst raw materials.

Physicochemical Property of Molybdenum trioxide powder

White crystalline powder. d26 4.6961 melting point 795℃; Boiling point 1155℃. Soluble in ammonia, alkali solution, hydrofluoric acid, concentrated sulfuric acid, insoluble in water. It is very stable in the air, through the dry hydrogen chloride, heated to sublimate into a light yellow needle crystal.

Production methodprocess of Molybdenum trioxide powder

Ammonium molybdate thermal decomposition method crushed molybdate concentrate to 60 ~ 80 mesa, put it into a baking furnace at 500 ~ 550℃ oxidation roasting, leaching with ammonia, ammonium molybdate solution removed impurities, heated to 40 ~ 45℃, adding nitric acid under agitation to neutralize to Ph=1.5, resulting in ammonium octamolybdate precipitation, filtered, centrifuged and dehydrated, dissolved in 70 ~ 80℃ ammonia. Ammonium paramolybdate was obtained by evaporation and concentration. Molybdenum trioxide powder was obtained by thermal decomposition at 550 ~ 600℃.
