The addition of a few nanometers of a thin layer of aluminum oxide protects a perovskite solar cell against humidity - still a major stumbling block to the commercial application of this new type of solar cell.
Today China's manufacturing industry encounters many difficulties, of which is the rising labor costs. Abrasives industry is a labor-intensive industry, which is particularly sensitive to the rise and fall of labor costs, especially for enterprises in the
Sapphire is basically aluminum oxide in its pure from which has no porosity or boundaries, and hence dense in nature. Low dislocation and high purity have led to adoption of sapphire as an ideal material to be used in wide range of electronic substrates.
Chinese domestic alumina prices are expected to see further support in the near term on the back market talk that the state environmental authority has clamped down on several major refiners and smelters this week, multiple market participants said Friday
High-resolution transmission electron microscopy shows that after just one laser pulse of 30 nanoseconds, the silicon carbide (SiC) substrate is melted and separates into a carbon and a silicon layer.
According to the latest China customs statistics, China's exports of silicon carbide were about 27000 tons in October, with 18.2% growth from last month, and 40.7% growth on year-on-year basis.
To the first quarter of 2017, the monthly production capacity of electrolytic aluminum will go more than 3 million tons, and the production release will push up the prices of the upstream alumina.
The Global Silicon Carbide Market is expected to reach USD 4.49 billion by 2020, according to a new study. Positive outlook on steel manufacturing, for which SiC is used as a deoxidizing agent is expected to drive silicon carbide demand.
According to introduction, after resuming production of Alpart alumina refinery, it will bring more than 800 jobs in Jamaica, and alleviate the pressure of the local employment. Jamaica is extremely rich in high grade bauxite resources.
Unlike alumina and aluminium, the bauxite market is experiencing strong growth, mainly due to demand from China. (Bauxite is refined into alumina, which is smelted into aluminium.)
Rohm Semiconductor is now fabricating devices in a 3rd generation of silicon carbide (SiC) technology, for MOSFETs, SiC Schottky Barrier Diodes (SBDs) and SiC modules.
SMM expects China’s alumina imports to increase slightly in the future since imported alumina has regained price advantage after big gains of domestic alumina prices.
Now, calculations by researchers in the US indicate that defects in silicon carbide (SiC) – which is CMOS-compatible – may have winning attributes to fit these requirements.
Two deals for alumina and electrolytic aluminum, the transaction volume of alumina is 2793 tons a, about 2780 Yuan per ton, and electrolytic aluminum about 200 tons, 14210 Yuan per ton.
Two kinds of abrasives are available in global abrasives market as synthetic and natural. Most of the natural abrasives have been replaced by synthetic abrasives in the abrasives market due to their consistent properties as required in industrial applicat
On November 17, in Shanxi, the market price of alumina was 2770 Yuan/ton, and the valid period of this offer is only for 3 days. In the same day, the market price of Henan alumina was about 2800 Yuan/ton, also kept for 3 days.
Caustic soda is a critical raw material for production of alumina, which is an intermediate product for production of aluminium, and contributes around 15% to the cost of alumina production.
Aluminum prices rose significantly in 2016, especially since late September, thanks to falling inventories, growing consumption, as well as higher costs from rising alumina and coal prices. Will the upward momentum carry into 2017?
Ceramic grinding wheels produced by Noritake Co. in Nagoya, usually used to cut or grind metal and glass, are gaining unexpected attention thanks to the increasing popularity of Japanese food in other countries.
Power strategist Kevin Speer of Littelfuse talks to Nick Flaherty about pricing, specification and the prospects for the latest wide bandgap power technologies, silicon carbide (SiC) and gallium nitride (GaN).
