Now researchers in Japan have developed a new method for coaxing graphene to behave as a superconductor that has some important and distinctive differences from the previous research by the Canadian and German researchers.
Compared with silicon carbide, the sapphire is an insulator instead of semiconductor on the structure. It can only make single sided electrode; Silicon carbide is conductive semiconductor that can do the vertical structure.
China's aluminum production accounts for about half of the global output, and the annual exports is expected to hit a record high in 2015, which will further exacerbate the global oversupply.
Superior grinding performance and flexible technological characteristic of abrasive belt determine that it has extremely broad application range - all walks of life from daily life to the industrial production.
We have benefited a lot from the applications of polishing materials in the traditional fields, but polishing materials have more use values that are worth us to develop.
According to the survey, the current market price of silicon carbide is in a clutter, and the price adjustment is because of the "inventory". There is a decline in market demand and a tight budget before Spring Festival.
Researchers at University of California-Los Angeles made silicon carbide nanoparticles into magnesium and zinc alloy in the solution, which generated a kind of metal nano composite material.
This article introduces the concentration and particle size analysis of abrasive grains.
In order to understand abrasives products and technology application in the manufacturing process of wood products, a factory director leaded a reporter into a production workshop.
There are many kinds of grinding wheel products that have all sorts of shapes and sizes. According to different abrasives, bond materials and manufacturing process of grinding wheel, each kind of grinding wheel has a certain application scope.
This article introduces the unconventional uses of super abrasives grinding wheel. Please click the link to view more details.
Analysts from Citigroup expect that alumina prices will rebound under the influence of global reduction of production.
It is reported that many large refineries will have a meeting this week to discuss how to raise its offer jointly, but a lot of market participants say that it fails and the price remains unchanged.
According to the current price of alumina, many alumina refineries in China are not profitable. Domestic alumina refining industry is facing a “Dilemma”.
Alumina output was about 15.7 million tons in Shandong district in 2015, with year-on-year growth of 31%, whose production accounting for 30.5% of the total national output, continued to rank the first place.
There are three important factors that affect the percentage of outturn. The first factor is laying-off, and the second is the grinding whose proportion of waste material has accounted for 35% of the total loss.
From the point of the market prices of aluminum oxide in recent months, we can find that the market price regulation is more flexible in Xiaoyi region, whose market prices have faster reaction for changes of supply or demand.
Alumina is an important part in the production process of electrolytic aluminum. The qualitative analysis and research on the alumina content are very necessary.
In 2015, the team has achieved the following results: successfully produce polysilane (PMS); successfully synthesize carbon silane (PCS); Solve fabrication technology of some liquid hyperbranched poly carbon silane (LHBPCS).
There is only a very thin layer of cubic boron nitride particles sticking on the surface of CBN grinding wheel,but its toughness,hardness,durability is about 100 times more than corundum grinding wheel,extremely suitable for hard-to-grind steel materials.
