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. Density 4.692g/cm3, melting point 795℃, boiling point 1155℃, easy to sublimate. 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. Molybdenum trioxide powder is produced by burning molybdenum or molybdenum disulfide in air or roasting molybdic acid.

Applications/Functions of Molybdenum trioxide powder

Physicochemical Property of Molybdenum trioxide powder

Colorless or yellowish-white powder, rhombic crystal system. Very slightly soluble in water, soluble in acid, alkali and ammonia aqueous solutions.

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℃.
