Yellow tungsten oxide is a common name of tungsten trioxide (WO3) from its appearance – yellow powdery crystals, which has excellent characteristics such as electrochromism, photochromism, and gasochromism. Well, do you know what are applications of yellow tungsten oxide?

Tungsten carbide shield cutter is an important part of shield tunneling machine, and supercoarse tungsten carbide is an important raw material for manufacturing the shield cutter. According to the experts, with the development of domestic shield technology, shield tunneling machines are more and more widely used in subway, municipal and underground pipe network construction projects. As the key raw material of shield cutter, the performance of tungsten carbide determines the life of shield cutter, and also determines the digging efficiency and economic benefit of the entire project.

Yellow tungsten oxide, which is also referred to as tungsten trioxide or WO3, has excellent electrochromic property. It is excellent electrochromic property that makes yellow tungsten oxide become a typical cathode electrochromic material. And the amorphous WO3 film is considered to be one of the most promising electrochromic materials. And therefore, WO3 is often seen in researches on electrochromic devices such as smart windows.

Tungsten carbide spiral flute tap is a kind of tapping tool, and it is also well-known as the most mainstream tool for processing internal thread. The processing speed of spiral flute taps made using high quality tungsten carbide powder as raw material is several times faster than that of high-speed steel spiral flute taps. It means that using the tungsten carbide spiral flute tap, the processing efficiency is high and the cost is relatively low.
