Tungsten market: recent domestic economic environment remains in the doldrums, tungsten downstream demand remained weak, tight liquidity market businesses generally. Tungsten concentrate prices almost bottomed out, buyers bargain Inquiry increased, but traders reluctant to sell, the actual turnover scarce, price is relatively stable, more tungsten scrap some traders stock market, worries about the market outlook began to increase, the proposed recent shipments may be appropriate, tungsten market is expected in summer or difficult to have a big breakthrough.

Researchers in China have taken a major step towards overcoming one of the main hurdles that is hampering the exploitation of carbon nanotubes for many high-tech applications – how to synthesise chirally pure samples.

The chirality of a single walled carbon nanotube (SWNT) is defined by the diameter of the tube and the wrapping angle, or twist (m), expressed as the index (n,m). Slight changes in these parameters can lead to markedly different properties, so being able to produce a single chirality on demand would represent a major step forward. So far, however, this has proved challenging.

Now, researchers led by Yan Li of Peking University have developed a nanocrystalline tungsten-containing alloy catalyst that that produces SWNTs with more than 90% uniform chirality of the form.

Chemical vapour deposition (CVD) methods of producing SWNTs rely on a carbon-containing vapour, such as ethanol, attaching to nanocrystals of a metal-containing catalyst, whose structure largely determines the chirality of the resulting nanotube. Typically these catalysts contain mixtures of metals such as iron, nickel, copper or cobalt.

Recent domestic economic environment remains in the doldrums, tungsten downstream demand remained weak, tight liquidity market businesses generally. Downstream manufacturers and product unmarketable because of funding constraints, while procurement is not active, actively lower prices; Scheelite high cost stock traders, shipping basically are faced with upside risks, so low will ship, and try to purchase low-cost supply of working capital , with low price and reduce risk.

It is understood that, because the market generally facing funding constraints of this problem, so now many products are tungsten cash transactions, especially tungsten ore, non-cash does not ship. Due to the current inquiry was okay, less low-cost supply, resulting in the difference of 55-65 grade tungsten ore pulled a small, 55-grade tungsten concentrate purchase price is 105,000 yuan / ton, 60 more than the price buyers are willing to accept 10.5 -10.6 yuan / ton.

Tungsten market: Tungsten City continued weak run, demand continues to slump dragged down by excess supply, tungsten prices steady kicked upstairs, thinly traded, and only a small amount of the transaction are also trading, APT market downturn in overall demand, market inquiry single-less, if there is no long-term acquisition of APT do inventory, market transactions or worse than tungsten concentrate. Sodium tungstate increasingly weak demand, the overall market showed a downturn trend, manufacturers or reduced sodium tungstate run, or suspend production sidelines ahead, manufacturers sluggish sales, is expected this week tungsten City or weak die hard.
