Chinese Tungsten Market Is Weak in Earlier December

Analysis of latest tungsten market from ChinaTungsten Online

Chinese tungsten market remains weak adjustment in the first trading day of December on high pressure of funds. Although enterprises plan to stock up before the Christmas, the demand side continues to be weak with poor market confidence. 

Under the environmental protection inspection, tight supply and high production costs offer supports for the market, but the benefits are disappearing. At Cemented Carbide Tool present, sellers in the tungsten concentrate market have no willingness in lower product prices; APT smelting factories, pressed by costs and funds, become difficulty in production and sales. 

Given that, short-term tungsten market will continue to be in the downward trend. Buyers will slow down to purchase while Cemented Tungsten Carbide sellers are reluctant to sell at low prices with the decline in profits. Market participants are waiting for clear guidance from the market.

GS Yuasa Lithium Batteries Power American Probes

GS Yuasa's lithium batteries fitted in the NASA's Radiation Belt Storm Probes in orbit to complete primary and extended mission operations. GS Yuasa Corporation is a Japanese company that makes lead-acid automobile and motorcycle batteries. The company also develops and produces advanced battery technology for various aerospace and defense applications, is actively demonstrating its influence in the field of lithium battery applications.

Foreign media reported tungsten carbide suppliers that two Radiation Belt Storm Probes launched by the NASA have completed their primary and extended missions after 7 years in orbit, and receive he shutdown command of the executive of the Johns Hopkins University Applied Physics Laboratory (APL).

The probes contained a battery consisting of 50Ah/3.7V GS Yuasa lithium batteries to get enough power in orbit. When the mission of the probes is to be extended, APL is set to use the long-life lithium-ion batteries developed by the company to support the detector in normal operation throughout their 7-year life in HEO orbit without changing the battery.

It is understood that the company has provided lithium-ion batteries for more than 190 domestic and international satellite programs supporting missions of communication spacecraft exploration. Its lithium batteries supply ranks first in the industry without any deficiencies or malfunction, indicating that its lithium-ion batteries hold a strong competitive advantage in terms of the life cycle, safety and quality.

In recent years, the company is strengthening its business layout in the new energy field. Besides electric vehicles, the company is exploring other market segments as well, including motorcycles, aerospace, submarines, ships, energy storage, and other fields.

In August of this year, Nagasaki-based Oshima Shipbuilding Co Ltd has built an automatic ship "e-Oshima" with a zero-emission powered only by a battery system. And the large-capacity lithium battery system is produced by GS Yuasa.

In October, the company invested 29 million euros in the construction of its first European battery factory in Miskolc, Hungary. It also completed and developed a silicon metal electrode for the development of solid-state batteries. The energy density of its batteries is twice compared to the existing lithium-ion batteries.

In November, Zgcc Cemented Carbide the second Soryu-class diesel-electric attack submarine (SSK) for the Japan Maritime Self-Defense Force (JMSDF) was officially launched. The submarine equipped with a system of lithium batteries produced by GS Yuasa, replacing the traditional lead-acid batteries that were previously used in such submarines.

Tungsten Trioxide Denitration Catalyst Regeneration Technology

Recently, the State Environmental Protection Bureau delegation went to Jiangsu, Shanghai investigagion selective catalytic reduction denitration catalyst recycling and subsequent disposal. The study is mainly to promote the selective catalytic reduction denitration resource utilization and safe disposal of the catalyst after elimination, rational planning its whereabouts, thus to reduce the running cost of environmental protection, resolve the environmental issues.

 Denitration system has already become an important part of coal-fired power plant, wherein the tungsten trioxide denitration catalyst is the core part of SCR system which takes the higher proportion of total investment. Currently, the denitration catalyst commonly used in the market are based on titanium dioxide as the carrier, vanadium pentoxide as the main active ingredient, tungsten trioxide (and / or molybdenum trioxide) as the anti-oxidant, anti-sulfide, anti-toxic auxiliary component. Theoretically, as the catalyst, it doesn’t as a reactant and cannot be consumed, so its effect is supposed to be permanent. However, in China, the catalyst market is now really staying in a relatively chaotic situation; usually, the catalyst will be deactivation after about three years. The main reasons which cause catalyst deactivation are Cemented Carbide Cutting Tool sintering, poisoning, intoxication, calcium, alkali metal poisoning, and poisoning of sulfur trioxide, and the voids plug fouling of catalyst, ect.. The regeneration or replacement of denitration catalyst will directly affect the running costs of the SCR system, therefore, the research on SCR catalyst deactivation and regeneration has an important practical significance. In practical applications, the regeneration techniques of failure tungsten trioxide denitration catalyst are generally the two kinds of live regeneration and plant regeneration. Since the site regeneration will pollute the around environment and water quality of the plant, also the quality and performance of catalyst which regenerated in the site are poor, and therefore, plant regeneration is the development direction. SCR catalyst is impregnated plant regeneration during a series of cleaning, ash removal, solid tungsten carbide rods ultrasonic treatment, the active ingredient (vanadium, tungsten, molybdenum, etc.), and finally achieve the goal of restoring catalyst activity.
