Physical and Chemical Properties of Cesium Tungsten Bronze:

The molecular structure of cesium tungsten bronze is oxygen octahedral structure, the purity is higher than 99.9%, the bulk density is 1.5g/ml, the particle size is relatively uniform, the primary particle size is about 30nm, the specific surface area is about 50m2/g, and it is not easy to agglomerate, non-toxic , Non-radioactive features.

The Production Method of Cesium Tungsten Bronze:

Method 1: Preparation of Cs0.33WO3 from Na2WO4•2H2O and Cs2CO3

1. Using sodium tungstate Na2WO4•2H2O as raw material, prepare a sodium tungstate solution with a concentration of 0.5 mol/L.

2. Obtain tungstic acid sol by cation resin exchange, add citric acid (analytical grade) solution with a concentration of 1 mol/L or 2 mol/L and a cesium carbonate Cs2CO3 (analytical grade) solution with a concentration of 0.3 mol/L, and stir evenly , to obtain the precursor for the hydrothermal reaction.

3. Put the precursor solution into the autoclave, react at 190 ℃ for 3 days, and then go through ultrasonic washing, alcohol washing, centrifugation and drying to finally obtain Cs0.33WO3 powder.

Cesium Tungsten Bronze Application:

1. Transparent thermal insulation coatings and films.

2. Thermal insulation chemical fiber, textile fiber and other high-performance thermal insulation media.

3. Transparent heat insulation window film, building coating.

4. Auto film, PVB heat insulation laminated film, laser marking, laser welding, photothermal diagnosis and treatment, infrared filter.
