Researchers in Sweden are building 3D silicon carbide devices on standard silicon wafers as part of a €8m international project
The zirconia-alumina abrasive disc delivers optimum stock removal on high-powered angle grinders at high contact pressures, according to the manufacturer. It is available in grit sizes 40 and 60 in a Type 29 (conical) shape.
Vietnam’s Vinacomin plans to change the terms of its alumina sales contracts, giving the seller rather than buyer, the option of shipping in bulk or bags, a company official said.
Positive outlook for steel manufacturing, for which silicon carbide (SiC) is used as a deoxidizer, is expected to drive the SiC demand. Moreover, SiC is a key element in the production of semiconductors. This is expected to witness a huge growth in future
Small changes in setup routines, equipment maintenance, and work flow can make big differences in setup time.
Recently, China Hongqiao came under attack from short-seller Emerson Analytics, which alleged in a research report that Hongqiao had under-reported the cost of its self-generated power and alumina and that the share price should be worth only HK$3.1...
“We continue to invest in silicon carbide and high density packaging to help the U.S. Army to better manage on-board power. This component provides the additional benefit of eliminating the need for an electronic cooling system.”
The Australian alumina daily assessment was static Thursday at $342.50/mt FOB, although it has declined $6.50/mt in the last week, dragged by stockbuild in China. On Thursday, indicative bid, ask levels were $340-$341/mt FOB Australia, versus $345-$350/mt
The plan would cut capacity for both aluminum and alumina by about 30%. Those figures represent about a 5% loss in China's annual aluminum production and a 9% drop in alumina output.
Researchers led by mineralogist Chi Ma have identified three new minerals in a tiny sample of the Khatyrka meteorite. The meteorite, recovered in pieces from the Koryak Mountains in eastern Russia
These are the key aluminum and alumina production areas. Deutsche Bank‘s Grant Sporre has the numbers:
Researchers have recently discovered that silicon carbide (SiC) can host colour centres in which an electron spin can keep its orientation for a long time – a prerequisite for making solid-state quantum bits and nanoscale magnetic sensors.
That may yet prove a conservative estimate, though. The new directive will also impact raw material suppliers such as alumina refineries and carbon anode plants, sending shock waves down the length of the global aluminum supply chain.
Steel and aluminum producers in 28 cities are told to slash output in winter and government begins moves to ban truck transport for coal.
Although Australian alumina has become too pricey for a large number of Chinese smelters, there has been a steady drip of buying among other consumer, trader and producer market participants worldwide, in the last couple of weeks.
In February, the prevailing prices of white fused alumina section sand Al2O3≥99% are around 4900-5100 Yuan/ton, and fine powder around 5100-5300 Yuan/ton (the prices including tax) in Henan, with prices unchanged from early last month.
After the rapid downfall in magnesia prices out of China following the scrapping of the quota system, some suggest the downtrend may be reversed if the shutdowns lead to a supply shortage.
“Corundum is a crystalline form of aluminum oxide and may be found in various colors, many of which are generally referred to as sapphire,” Apple explains.
Quality control factor of silicon ceramic is of top priority when it comes to top class product manufacturing. Shanghai-based manufacturer industry provides durable ceramic products with top class quality assurance.
“This is a very important market for us and we want to serve it correctly. It is sensible for us to do so from within Germany so that we can respond swiftly and effectively to all needs.”
