Ammonium metatungstate powder can be used to prepare tungsten oxide nano aqueous solution, and thus be applied to the production of transparent thermal insulation material, which is energy-saving and environmentally friendly of high heat insulation performance.

The following is a new method for preparing three kinds of tungsten oxide nano aqueous solutions, and the particle size of the nano tungsten oxide in the obtained aqueous solution is different.

Method one: Take 10ml of deionized water in a beaker, weigh 1g of ammonium metatungstate into deionized water, add 5g of sodium borohydride, mix and shake, and let stand for 20min at room temperature (20°C) to obtain the tungsten oxide nano aqueous solution of a particle size of 1nm.

Method two: Take 10ml of deionized water in a large beaker, weigh 5g of ammonium metatungstate into deionized water, add 5g of sodium borohydride, mix and shake, and let stand for 10min at room temperature (20°C) to obtain the tungsten oxide nano aqueous solution of a particle size of 0.1-1nm.

Method three: Take 10ml of deionized water in a beaker, weigh 50g of ammonium metatungstate into deionized water, add 5g of sodium borohydride, mix and shake, and let stand for 60min at room temperature (20°C) until no gas is produced. So, the tungsten oxide nano aqueous solution of a particle size of 5-30nm was obtained.
