Properties    


Colorless or pale yellow-green diamond-shaped crystal, relative density 2.498g/m3(20°C). Stable in the air, its aqueous solution is weakly acidic, the solubility in the aqueous solution of 20° C and 80-90°C, respectively, equal to 300 g / l and 500 g / l. Heated to 90°C, will loss a water of crystallization, 170 ~ 190°C, broken down into ammonia, water, and molybdenum trioxide. Placed air weathering, and lose some ammonia. Soluble in water, acid and alkali, and insoluble in ethanol. Toxic, the maximum allowable concentration in the air is 2mg/m3.
