CsxWO3 Applied for Thermal Insulating Glass

The preparation of CsxWO3 for thermal insulating glass is one of the key concerns of manufacturers and scholars who are just getting started. Now, let us take a look at how to prepare Cs0.3WO3 powder with Cs/W (molar ratio) = 0.3:1.

Preparation of Cs0.3WO3 Powder

Step one: weigh a certain amount of sodium tungstate, dissolved in deionized water, and prepare 0.5mol/L sodium tungstate solution, and ion exchange of sodium tungstate solution with styrene cation exchange resin to obtain 0.5mol/L tungstic acid solution;

Step two: Measure 20ml of 0.5mol/L tungstic acid solution, put it into a beaker, add 12.6g of citric acid once in stirring, stir well, then slowly add 5ml of 0.3mol/L cesium carbonate solution, then adding 30ml of absolute ethanol and stirring for 1 hour to obtain a reaction precursor solution;

Step three: Transfer the prepared reaction precursor solution into the autoclave, and continuously hydrothermally reacting at 190°C for 3d;

Step four: Wash the precipitate with water and alcohol three times in sequence, and after centrifugation, it was dried in a sub-vacuum at 50°C for 10h to obtain Cs0.3WO3 powder.
