As a kind of multi-functional material, ultrafine W₁₈O₄₉ nanowire has high application value in many important fields, such as gas-sensing materials, sensors and photodetectors. It is usually prepared by solvothermal method, which is simple and environmentally friendly.

Ultrafine W₁₈O₄₉ nanowire is prepared by WCl₆ and triethylene glycol. During the preparation process, WCl₆ is used as precursor, and triethylene glycol is used as solvent. This is an efficient and environmentally friendly preparation method.

iolet tungsten oxide exhibits a strong, tunable localized surface plasmon resonance effect, which results in its light absorption in the near infrared region. Based on this light absorption property, photothermal conversion material of nano violet tungsten oxide is successfully prepared. It has application value in the treatment of cancer.

As violet tungsten oxide has high chemical activity and good air permeability, it is suitable for the production of ultrafine tungsten powder and tungsten carbide powder. At present, a kind of electric heating furnace is applied in the production of violet tungsten oxide.

The preparation of high-quality violet tungsten oxide has attracted more and more attention. In addition to improving the preparation process, upgrading the preparation device can also improve the quality of violet tungsten oxide effectively. Sealed multi-purpose furnace is suitable for the production of high-quality violet tungsten oxide.

Violet tungsten oxide with unique needle structure and high chemical activity has broad application prospects in the preparation of tungsten powder and tungsten carbide. Generally, it is obtained by calcining ammonium paratungstate in a calciner.

As a kind of multi-functional material, violet tungsten oxide has high application value in many fields such as fuel cells and thermal insulation materials. It is generally prepared by calcining ammonium paratungstate in a rotary furnace. The selection of rotary furnace is the key to high-quality violet tungsten oxide.

Violet tungsten oxide is an important raw material for the preparation of tungsten powder. During the preparation process, the fluidity of violet tungsten oxide directly determines the feeding speed of rotary furnace. Only when violet tungsten oxide with high fluidity is applied, can high-quality tungsten powder be prepared.
