Recently, Professor Li Guowu from Crystal Structure Laboratory in China University of Geosciences has discovered a new mineral with tungsten bronze type structure--- wumuite. The new discovery was officially approved by IMA-CNMNC (Approval No. IMA2017-067a). This is the first natural mineral with tungsten bronze type structure found in the world.

China ammonium paratungstate (APT) and ferro-tungsten prices continued their downward trend earlier in this week amid quiet trading volumes in Chinese market and lackluster demand from the overseas market. 

Rare earth market quotation in China: rare earth price remains unchanged from the previous trading day. Sellers appear unwilling to sell with the support of production costs while downstream customers still remain low buying interest in off-peak season. Under unclear outlook, insiders have different opinions on price trend in September. 

The latest prices of molybdenum concentrate, sodium molybdate, ammonium molybdate and molybdenum bar go up on Tuesday August 28. Under the environmental inspection, large mines stop production to undergo repair, offsetting some disadvantages of weak demand. 

Photocatalysts are chemical substances which do not change itself under the irradiation of light and can be used as a catalyst. 

Photocatalytic principle: After the photocatalyst is irradiated by light, the valence band electron on the semiconductor surface absorbs the light and is excited to the conduction band. 

Tungsten diselenide nanosheet is a kind of two-dimensional graphene-like material. Its main structure is composed of two layers of selenium atoms connected with a layer of tungsten atoms in the middle. This material is a hot research topic in the scientific community. 

With the rapid development of graphene, people get interested in two-dimensional materials. Among these two-dimensional materials, transition metal dihalide has attracted extensive attraction because the thin layer structure of its atom owns the properties of electricity, optics, plasma, electrochemistry and electrocatalysis.

Affected by new round of environmental protection checks, sellers became more confidence and tended to stabilize offer levels. However, usual quiet trading activity and lowered tungsten forecast prices from large enterprises and associations still made trading deadlocked. 

Rare earth market quotation in China: domestic rare earth price continues to be stable earlier in this week due to deadlocked supply and demand, weak demand in off-peak season and thin trading. Insiders expect that some downstream factories will start to purchase gradually and that will help to rise prices. Sellers now are reluctant to sell, waiting for listing prices of large enterprises. 

Affected by environmental protection tightening the supply, Chinese molybdenum prices climb from last week. High production costs and increasing quantity in steel biddings boost market confidence.
