Blue Tungsten Oxide Application.
Strengthening the tungsten skeleton sintering and infiltration is being another blue tungsten oxide application.
Enamle Blue Tungsten Rings OAGR0131.
Therefore, when people say tungsten oxide, it usually means blue tungsten oxide, whose chemical formula is WO2.9.
Blue Tungsten Carbide Tapered Chisel Drill Bit Flat Chipways.
Tungsten chloride will decompose in water, the product may be blue tungsten oxide or tungsten oxide hydrate.
PS: Blue tungsten oxide is the mix tungsten oxide of W20O58.
When reducing tungsten trioxide to tungsten powder, it will turn into blue tungsten oxide first then gradually reducing to tungsten powder.
PS: Blue tungsten oxide is the mix tungsten oxide of W20 O58.
Technical requirement 3.1 Yellow tungsten oxide is light yellow crystalline powder, blue tungsten oxide is dark blue or black blue crystalline powder.
Blue tungsten oxide(BTO) is also called tungsten blue oxide(TBO).
It is suitable for tungsten trioxide and blue tungsten oxide which is used to producing tungsten powder. Product specification.
Blue tungsten oxide is used primarily for the production of tungsten metal powder and tungsten carbide.
Ammonium paratungstate is mainly for the manufacture of or tungsten trioxide or blue tungsten oxide, thus to prepare metal tungsten powder;
Doping in blue tungsten oxide or tungsten oxide mixed with trace K2O, Al2O.
Chinatungsten Online manufactures three types of tungsten oxide, blue tungsten oxide, yellow tungsten oxide and violet tungsten oxide.
Blue tungsten oxide(BTO, WO2.9) is primarily used to produce tungsten metal powder for fine tungsten carbide powders and wire.
Yellow tungsten oxide is yellow or yellow green, blue tungsten oxide is dark blue, violet tungsten oxide is dark purple, tungsten dioxide is dark brown.
Blue tungsten oxide and yellow tungsten oxide are more regular products than violet tungsten oxide and tungsten dioxide.
Thus, with a certain crystal form and large specific surface area of blue tungsten oxide application is more extensive, it will further promote development of ultrafine tungsten and tungsten carbide powder.
Blue tungsten oxide preparing method mainly is ammonium paratungstate(APT) closed calcination, APT hydrogen mild reduction and internal reduction method, the front two are mostly used in industrial of China.
Analyses of blue tungsten oxide as follow.
Blue tungsten oxide which shorted for BTO, yellow tungsten oxide which shorted for YTO, violet tungsten oxide which is shorted for called VTO and tungsten dioxide are all called tungsten oxide.
Tungsten blue, as known as blue tungsten oxide, BTO, Î2- tungsten oxide, hence the name as appearance of blue powder.
Blue tungsten oxide application mainly reflects in it as an intermediate in metallurgical industry for manufacturing tungsten powder and other tungsten material(tungsten and tungsten carbide), blue tungsten oxide(BTO) is an important raw material;
Common tungsten oxide are tungsten oxide, blue tungsten oxide, violet tungsten oxide and tungsten dioxide,Tungsten oxide property mainly are conductivity, ferromagnetism, catalytic and other properties.
Add a certain amount of blue tungsten oxide in the production process, using its reducing property to produce different size tungsten powder ensure communication aperture smoothly formed, to realize the purpose of forming a backbone network with a certain strength at lower temperature.
Studies have pointed out that a preparation method for preparing blue tungsten oxide with high-surface area, which the product has higher specific surface area, larger chemical activity, faster hydrogen reduction than the normal blue tungsten and further expands the blue tungsten oxide application.
Moreover, since it is relatively easy to control particle size and size distribution in blue tungsten oxide reduced to tungsten powder, it is benefit for doping other elements in the tungsten powder reduction process, thus BTO is gradually replacing tungsten trioxide as the raw material of producing special tungsten, tungsten powder.
Add a few drops of copper solution, shaking to fade tungsten blue.
