Yellow tungsten oxide, which is known as tungsten trioxide (WO3), is a transition metal oxide with excellent photochromic property. For example, WO3 film turns blue when irradiated by ultraviolet light (in the sunlight). And the research on the photochromic property of yellow tungsten oxide can be explained by the dual charge injection – extraction model. More details, please visit: http://tungsten-oxide.com/index.html The dual charge injection – extraction model points out that after WO3 is irradiated with ultraviolet rays, the electrons in…

Yellow tungsten oxide, which is well-known as tungsten trioxide or WO3, is a semiconductor material developed in recent years with excellent gasochromic property. So, WO3 is often used as a gasochromic material for applications of different gas sensors such as NO2 sensors. The gasochromic property of yellow tungsten oxide is often explained by the polaron model. The following is an example given by the researchers. More details, please visit: http://tungsten-oxide.com/index.html Taking hydrogen as an example, hydrogen molecules are chemically adsorbed…

Yellow tungsten oxide is more often called as tungsten trioxide (WO3). And discoloration property of yellow tungsten oxide refers to the excellent color-changing performance of tungsten trioxide such as electrochromic performance, photochromic performance, and gasochromic performance. These unique properties of WO3 make it have great application prospects in the fields of electrochromic devices such as smart windows, optical devices, and gas sensors. More details, please visit: http://tungsten-oxide.com/index.html So, do you know what is the discoloration property of a material? The…

Yellow tungsten oxide nanowires, which are also known as tungsten trioxide nanowires or WO3 nanowires, are a unique N-type semiconductor material that exhibit good characteristics in terms of photocatalysis, electrochromism, photochromism, gasochromism, etc. Therefore, WO3 is often used as a photocatalytic material, an electrochromic material, a photochromic material or a gasochromic material, etc., for applications in photocatalytic degradation of organic and inorganic pollutants, hydrogen production from photolysis of water, color-changing devices (smart windows, etc.), photoelectrochemical devices, gas sensors (NO2 gas…

Tungsten carbide flowdrill is also called tungsten carbide fdrill that is environmentally friendly, wear resistant and high temperature resistant to drill hole with stability, high precision and beautiful surface. It provides a perfect solution for thin-wall drilling connection. Well, do you know what are advantages of tungsten carbide flowdrill? More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-drill.html Advantages of Tungsten Carbide Flowdrill 1. Improve production efficiency.

High precision tungsten carbide flowdrill is well known as a drilling tool that can process holes on thin workpieces such as thin plates and thin tubes with advantages of high accuracy, high speed, beautiful surface, and low cost. Such a drill bit is wear-resistant and high-temperature resistant to be used at bad conditions. This drill bit uses the basic principle of generation of heat by friction to drill holes with bushings in tubular or plate metal workpieces, which is a…

Tungsten carbide flowdrill with double heads is solid, stable, wear resistant and high temperature resistant as it is made of high-quality cemented carbide material that mainly composed of tungsten carbide powder and cobalt powder. The flowdrill is mainly applied to a chipless drilling process – fdrill process. And such a flowdrill bit is suitable for processing ordinary steel, stainless steel, aluminum, copper and other workpiece materials that are malleable. Also, it can be used to drill electroplated workpieces. More details,…

What is working principle of tungsten carbide flowdrill? You know, tungsten carbide flowdrill is a wear-resistant and high-temperature resistant drill bit for flowdrilling processes. The flowdrilling process is a chipless machining technology that processes holes and bushes on a metal sheet or tube at one time. Such a process has completely replaced the process of welding and riveting a nut on a thin-walled workpiece. Therefore, it is necessary for us to understand the working principle of flowdrill. More details, please…

Tungsten carbide graver is also known as cemented carbide graver, which has higher hardness, better wear resistance and longer service life than the commonly used carbon steel graver and white steel graver. Wherein, carbon steel graver is generally suitable for beginners as it has low hardness and strength. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html The tungsten carbide graver can be made of carbide materials such as YG8 – has good wear resistance, hardness of 8-9, and density of 14.5-15.9. What should…

New tungsten carbide glass cutter adopts a tungsten carbide substrate as the cutter body. And it is coated with a diamond-like coting of thickness of 1-10 microns. The diamond-like coating on new tungsten carbide glass cutter can improve the hardness and wear resistance of the cutting edge. When cutting hard glass, the coating film can significantly increase the life of the glass cutter. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html So, why choose a diamond-like coating instead of a diamond coating? The…
