Tungsten Blue Oxide Uses

Details: Category: Tungsten Information; Published on Thursday, 05 February 2015 11:10; Written by cq; Hits: 1600

Blue tungsten oxide (BTO) is also called tungsten blue oxide (TBO). Tungsten blue oxide is one of the most important, highly pure intermediates for the production of other tungsten compounds including tungsten metal powder.

Tungsten blue oxides are finely divided blue-violet powders.They are produced by heating ammonium paratungstate at closely controlled temperatures in a reducing atmosphere. GTP produces two standard grades differing mainly in oxygen content. Tungsten blue oxide is used primarily for the production of tungsten metal powder and fine tungsten carbide as well as wire products.

Violet tungsten oxide (VTO) is a kind of tungsten oxide. Violet tungsten oxide is a finely divided violet crystalline powder. It is produced by rotary calcining ammonium paratungstate at closely controlled temperatures in a reducing atmosphere. Violet tungsten oxide is used primarily for the production of tungsten metal powder and tungsten carbide.

Partial Thermal Reduction of Ammonium Paratungstate Tetrahydrate

Details: Category: Tungsten Information; Published on Thursday, 05 February 2015 11:05; Written by zsq; Hits: 470

Thermal decomposition of ammonium paratungstate tetrahydrate, (NH₄)₁₀[H₂W₁₂O₄₂]·4H₂O has been followed by simultaneous TG/DTA and online evolved gas analysis (TG/DTA-MS) in flowing 10% H₂/Ar directly up to 900°C. Solid intermediate products have been structurally evaluated by FTIR spectroscopy and powder X-ray diffraction (XRD). A previously unexplained exothermic heat effect has been detected at 700–750°C. On the basis of TG/DTA as well as H₂O and NH₃ evolution curves and XRD patterns, it has been assigned to the formation and crystallization heat of γ-tungsten-oxide (WO_2.72/W₁₈O₄₉) from β-tungsten-oxide (WO_2.9/W₂₀O₅₈) and residual ammonium tungsten bronze.
