The regular sizes of tungsten wire can vary depending on the manufacturer and the intended application. However, some common sizes include:

At the beginning of the week, China tungsten market was in a stalemate with slow price increase and more manufacturers considering profit-taking. Since the beginning of this year, economic recovery expectations have continued to be revised upwards, but consumption data has not been released in batches during the repair cycle and under the influence of high raw material costs.

The researchers have designed a self-powering smart window system in which a bifunctional tungsten oxide based device serves as the glass and fibrous dye-sensitized solar cells serve as the frame of the window so that space can be used efficiently. The shining point of this new system is that the number of solar cells can be changed and when converted, it can make this integrated system independent of the angle of incidence as the frame is designed as a cylindrical configuration.

Regarding Electrochromic Energy Storage Devices (ECESDs), tungsten oxide could achieve greater capacity and richer colors if the suitable electrode is selected. There is a relationship between the energy storage level (ESL) of a bifunctional device based on tungsten oxide and its color, which is why qualitative information on the state of the device can be obtained directly.

In the application of electrochromic energy storage devices, the methods to improve the bifunctional properties of tungsten oxides electrodes are very similar to those used to improve electrochromic and energy storage properties: obtaining porous nanostructures, doping, and integrating tungsten oxide with other materials, especially organic materials. In most cases, these methods are not used individually, but two or three methods are used simultaneously.

China tungsten price edged higher at the beginning of the week began on Monday Feb. 6, 2023 and then stabilized when the weekend approached with the impact of rising new guide prices for the first half of this month as well as the strong earthquake in Turkey.

At the beginning of the week, China’s holmium oxide, neodymium oxide and praseodymium oxide prices continue to edge lower as last week, mainly due to the current poor market conditions in the auto market and the large inventory of raw materials in many magnetic material companies, which led to weaker market demand and lower rare earth prices. 

At the beginning of the week, China’s ferro molybdenum, molybdenum oxide and molybdenum powder prices start to decline slightly. 

When the tungsten oxide material is used in the electrochromic (EC) window of electrochromic devices (ECD), three modes can be achieved, namely, a bright mode when the transmittance of both visible and near-infrared light is relatively high; a cool mode when the transmittance of visible light is high and the transmittance of near-infrared light is relatively low; and a dark mode when the transmittance of both of them is low. cooling mode when the transmittance of both is low; and the dark mode when the transmittance of both is low.

Researchers fabricated 1D W₁₈O₄₉ nanomaterials for near-infrared shielding of electrochromic devices. These tungsten oxide films all had high transmittance in the visible region. However, the researchers did not explore the change in transmittance during the color change. The researchers fabricated a flexible electrochromic device (ECD) with 63% transmission modulation between 760 and 1600 nm, yet did not tap the relationship between the transmission of visible and near-infrared light.
