China molybdenum price continues to hit record high on December 21, 2022, and with the weaker confidence of suppliers, the increase pace slows down. The current prices of molybdenum concentrate, ferromolybdenum and sodium molybdate are consolidating at 3,940 yuan/mtu and 268,000 yuan/ton and 175,000 yuan/ton, respectively.

At the beginning of the week, China tungsten price stabilizes as the market keeps quiet and replenishment of downstream end users is limited. With the adjustment of domestic epidemic prevention and control measures and the recovery of logistics transportation capacity, the market outlook consumption is expected to gradually pick up, which will give a certain boost to the market trading.

China tungsten price was stable on the whole in the week ended on Friday December 16, 2022 when raw material manufacturers have rised mentality with Chinese government easing ‘Zero Covid’ restrictions.

Rare earth market quotation in China: terbium oxide, praseodymium oxide and neodymium oxide prices increase on December 19, 2022 due to strong rised mentality of sellers. 

Molybdenum market quotation in China: sodium molybdate, ammonium molybdate and ammonium heptamolvbdate prices remain stable on December 19, 2022 with the impact of the decline in international molybdenum price. 

The preparation of tungsten oxide film includes sol-gel technique from ethanol acetylated tungsten peroxide sols containing varying amounts of organic matter, namely oxalic acid dehydrate (OAD). The chemical properties of the precursor solution were changed by varying the proportion of dopants, allowing the microstructure of the films to be altered, which are otherwise amorphous to X-rays.

Tungsten oxide films are able to switch rapidly between transparent and blue states. These are the counteractions of the mesoporous structure and the interconnected nanocrystalline phases. Deepa et al. compared the electrochromic properties of sol-gel-derived amorphous and nanocrystalline tungsten oxide films. The pristine acetylated tungsten peroxide sol with and without the addition of 4 wt% oxalic acid dehydrating agent (OAD) produced nanocrystalline and amorphous tungsten oxide (WO₃) films, respectively, by the impregnation technique.

The researchers found that the thickness and content of the tungsten oxide film were found to vary depending on the concentration of the PAA coating solution (1.0-3.0 wt%), and thus the electrode performance of the PAA/WO₃ layer could be easily controlled. The special applications for WO₃ films include photoelectrochemical and electrochromic devices. Clara Santato et al. used a novel sol-gel method to prepare mesoporous tungsten trioxide nanocrystals consisting of preferentially oriented monoclinic phase semiconductor films.

China’s ferro tungsten and tungsten powder prices show a stable trend for the time being, mainly due to the strong rised mentality of raw material manufacturers. 

This week, China rare earth price showed a pattern of first stabilizing and then rising. Under the influence of both weak supply and demand and the increasing number of positive factors, the price game among traders was fierce, that is, the confidence of suppliers in firm quotations was generally strong, and the sentiment of buyers to suppress prices continued.
