Physicochemical properties (the following information is for reference only): yellow to light yellow green powder. When heated to 100-110 ℃, it slowly becomes dehydrated (2wo3 · H2O), and the high heat changes from nwo3 · H2O to tungsten trioxide. Soluble in hydrofluoric acid, slowly soluble in caustic solution, insoluble in water and other acids. The relative density is 5.5. Irritating
