Trump Issued an Order to Stimulate Production of Rare Earth Magnets

U.S. President Donald Trump on Monday ordered the U.S. Department of Defense to promote the production of large quantities of rare earth magnets for consumer electronics, military hardware and medical research, concerns that China would restrict exports.

Trump cited the 69-year-old Defense Production Act, once used to protect American steel-making capacity, to remedy what he called a "shortage" and to produce super-strong magnets made from rare earth minerals neodymium and samarium.

Trump issued a directive Monday that the ability of the United States to make magnets is "critical to national defense". Trump said that without action, U.S. industry "could not reasonably expect to provide unground solid tungsten carbide rods production capacity for its products".

The Defense Production Act allows the President to prioritize contracts for materials, equipment and services in order to maintain or build domestic manufacturing capacity. It is used to force the purchase of semiconductor manufacturing equipment so that companies can produce military radiation-enhanced microelectronics - a niche market in which businesses may not invest themselves. It is also used to finance research and procurement projects in lithium-ion batteries, light ammunition and other technologies.

Trump’s June executive report said the United States needed a stable supply of key minerals to ensure its economic prosperity and defense. At that time, the Trump administration promised to take “unprecedented action” to ensure that the United States would tungsten carbide burrs not Tungsten Carbide Rods Single Hole be disrupted by the supply of rare earths, a group of 17 minor but vital elements led by China.

Important Progress in Rare Earth Luminescent Nanoprobes

Luminescent probes are an important bio-visualization tool commonly used in many applications such as bioimaging and detection. Currently developed luminescent probes mainly include carbon nanotubes, fluorescent dyes, quantum dots and rare earth Tungsten Carbide Rods Single Hole doped nanomaterials. Among them, rare earth nanomaterials have become a research hotspot due to their advantages of good light stability and low biological toxicity. However, the rare earth nanomaterials generally used have problems such as low quantum efficiency and small light absorption cross section, and the research on the regulation of their properties is at an exploratory stage.

Under the support of the national key research and development program “Nano Technology”, Professor Li Fuyou's research team at Fudan University has developed a class of nanoprobes with the same excitation and emission wavelengths and long luminescence lifetime, with rare earth elements Yb, Er, Tm, Nd. Etc. as the main doping element has a unique zero Stokes displacement photoluminescence. Such a probe is like a short-lived memory that continuously produces the same illuminating signal as the wavelength of the excitation light for a period of time after excitation. Although the traditional wavelength-based luminescence detection method cannot fully study the luminescence phenomenon, researchers have developed a new signal collection method by using the characteristics of tungsten carbide strips this type of probe with longer luminescence lifetime, by controlling the illuminating collection window. After the pulse excitation, the excitation light is filtered out in the time domain to maximize the luminescence signal of such probes. For example, small-sized nanoparticles (~15 nm) with Yb as the main doping element have an emission intensity advantage of more than an order of magnitude compared to other commonly used luminescent materials. By adjusting the thickness of the shell in the core-shell structure, the luminescence lifetime of the material can be significantly adjusted.

In view of the unique properties of this type of material, the researchers developed it into a time-domain fluorescence imaging method for multi-channel decoding and live tracing in the time domain, and clinical applications such as passive targeting solid tungsten carbide rods of tumors, showing broad application prospects.

China Neodymium Oxide Price - February 4, 2021

With the increased festive atmosphere and weakened policy dividends, the activity of inquiries and purchases on the market has decreased, resulting in fewer new orders. In the short term, the industry will focus on the transaction status of the market after the holiday. 

The current neodymium oxide price is about 576,000 yuan/ton, neodymium praseodymium oxide price is about 458,000 yuan/ton, terbium oxide price is about 8,800 yuan/kg, and dysprosium-iron alloy price is about 8,800 yuan/kg tungsten carbide strips on February 4, 2021. 

According to customs data, in 2020, China imported 71,407 tons of rare earth metal ore from the United States, an increase of 54% from 46,149 tons in 2019 and Tungsten Carbide Rods Double Holes an increase of 159% from 27,567 tons in 2018. In addition, the average import price in 2020 has risen by 26%, reaching $1,648/ton.

Xiamen Tungsten’s Offer for Ammonium Metatungstate Declined in October

Analysis of latest tungsten market from Chinatungsten Online

The ferro Tungsten Carbide Round Rod tungsten and tungsten powder prices in China continue to maintain stability in the wake of a slight decline in new tungsten forecast prices from listed companies and associations. The new guide prices are basically in line with market trend and traders make quotes based on them. 

China’s Xiamen Tungsten’s offer for ammonium metatungstate (APT) stood at $22.5 per mtu, a slight decline of $0.9 per mtu from the second half of September.  

Jiangxi Tungsten quoted black tungsten concentrate at $13,230.8 per tonne, ground tungsten carbide rods down $307.7 per tonne from the late September. 

Now China’s economy and manufacturing industry is recovering steadily. However, the Covid-19 seems to be worsening in Europe, the Unite States, Brazil and India. The overseas markets face many uncertainties, which affects China’s import and export greatly. In the Tungsten Cemented Carbide short term, the market may continue to keep quiet.

China Ferro Molybdenum Price - November 12, 2020

Molybdenum market quotation in China: ferro molybdenum, tungsten carbide burrs molybdenum powder and molybdenum concentrate prices are unchanged from the previous trading day on November 12, 2020.

Driven by the good trading activity in the international molybdenum market, the enthusiasm of intermediate smelting companies and end customers to enter the market has increased compared with before. However, due to the heavier price reduction psychology, it is still difficult for holders to raise prices. There is no significant price fluctuation for the time being in the molybdenum chemical product markets. The molybdenum concentrate price has temporarily stabilized at 1,420 yuan/ton, ferro molybdenum price is around 98,000 yuan/ton, and molybdenum oxide price is about 1,510 yuan/ton. 

Although the steel bidding market is relatively calm, molybdenum companies have basically maintained firm quotations under the background that raw material inventories are not very abundant and production costs are high. Sales pressure is average, and transactions have yet to start. 

The increase in excavator sales reflects the gradual expansion of the infrastructure market, which has a positive impact on the steel market. According to the latest data from China Construction Machinery Industry Association, 27,331 units of various excavation machinery were sold in October, an increase of 60.5% over the same period last year. From January to October, a total of 263,839 sets of excavation machinery products were sold, an increase of 34.5% over the same period last year. Domestic sales increased by 34.5% year-on-year, and export sales increased by 25.9% year-on-year.
