Tungsten alloy shielding device plays an important role in shielding X-rays and γ-rays in a CT scanner. Some researchers have proposed such a new shielding device, which has a simple structure and excellent X-ray radiation shielding performance. The existing shielding devices are difficult to move. While this new device is easy to move during use.

Tungsten hexachloride is an important tungsten source for producing tungsten carbide composite catalytic material with platinum-like catalytic properties. For example, some researchers used tungsten hexachloride as the source of tungsten, the stripped montmorillonite sheet as the carrier, and combined the chemical impregnation method with the in-situ reduction carbonization technology to prepare tungsten carbide composite catalytic material - a nanocomposite of tungsten carbide and montmorillonite.

The researchers used tungsten-containing waste to prepare ammonium paratungstate (APT) by leaching, extraction and ammonium sodium double salt method. Therefore, tungsten is effectively recovered. The quality of the prepared APT is higher. And it can further prepare tungsten oxide from APT. This method reduces the process cost by effectively recycling the salt-containing waste liquid generated in the process, which is worthy of vigorous promotion.

Tungsten hexachloride can be applied for preparing porous WO3 film. Wherein, porous WO3 film is a common gas-sensitive material with excellent gas-sensing performance and gasochromic performance. In addition, it is a typical electrochromic material, and is considered to be one of the most promising electrochromic materials. Tungsten hexachloride (WCl6) is a raw material for preparation of new material that can be used in the chemical industry for catalytic applications, as well as in the glass industry, mainly for the production of surface coatings. So, what is the connection between the porous WO3 film and tungsten hexachloride?
