Ammonium Metavanadates

We are producing and exporting of Ammonium Metavanadates to our clients. The white/slightly yellow deliquescent crystalline powder is slightly soluble in cold water, hot ethanol and ether. Also dissolved in hot water and dilute ammonia. Turn into a toxic vanadium pentoxide. when burned in air. Sodium vanadate solution was washed with hydrochloric acid to the PH was adjusted to 7.5 ~ 8, then heated to 70 ~ 80 A C with a solution of ammonium chloride and carry out the reaction, the precipitate was separated by centrifugation, washed with water and dried to obtain a finished ammonium metavanadate. Mainly used as chemical reagents, catalysts, driers, mordant. It is widely used in the ceramic industry as glaze. Also be used for the manufacture of vanadium pentoxide. Ammonium metavanadate should be store in a cool, ventilated warehouse. Keep away from fire and heat. Prevent direct sunlight. Sealed packed. Have to stored separately from reductant, easy (can) combustible, food chemicals and avoid mixing reservoir. Storage areas should be equipped with suitable host material spill.
