Blue Tungsten Oxide (WO2.8-2.97)
Tungsten Blue
Blue Tungsten Oxide, which is short for BTO, is a kind of tungsten oxide. Blue tungsten oxide is powder shaped and blue displayed.
Blue tungsten oxide is a finely divided blue-violet crystalline powder. It is produced by rotary calcining ammonium paratungstate at closely controlled temperatures in a reducing atmosphere. CTOMS produces two standard grades differing mainly in oxygen content. Blue tungsten oxide is used primarily for the production of tungsten metal powder and tungsten carbide.
Blue tungsten powder is the most important precursor in the line from oxide to W and WC powder. The colour varies between deep dark blue to blue, faint blue and green blue. Also the BTO particles are pseudomorphous to the original APT crystals, as described for tungsten trioxide.
