Hydroxylated graphene

Hydroxylated graphene is an important functionalized graphene and plays an important role in covalently bonded functional graphene. First of all, it is a basic functionalized product, on which subsequent functionalized graphene can be carried out. Generally, graphite and alkali metal hydroxide soli…

High carbon ferro Chrome

High carbon ferrochromium is used as alloying agent for ball steel, tool steel and high speed steel with high carbon content to improve hardenability, wear resistance and hardness of steel; as additive for cast iron to improve wear resistance and hardness of cast iron, and to make cast iron have goo…

Hafnium dioxide

Hafnium dioxide (HfO2) is an oxide of hafnium, which is a white solid at room temperature and pressure. Melting point is 2780-2920K. Boiling point 5400K. The coefficient of thermal expansion is 5.8 x 10-6/. It is insoluble in water, hydrochloric acid and nitric acid, but soluble in concentrated sulf…

Germanium(Ⅳ) oxide

Germanium dioxide, the molecular formula GeO 2, is germanium dioxide, and the electronic formula is the same as carbon dioxide. It is white powder or colorless crystal. It is mainly used in the preparation of germanium metal, as well as spectral analysis and semiconductor materials. Germanium dioxi…

Fullerene C60-999

Fullerene C60-999 are hollow molecules composed entirely of carbon and are spherical, ellipsoidal, cylindrical or tubular in shape. Fullerenes are structurally similar to graphite. Graphite is a stack of graphene layers composed of six-membered rings, while fullerenes contain not only six-membered r…

About Fine zirconium metal powder

Zirconium is a chemical element, the chemical symbol is Zr, the atomic number is 40, is a light gray lustrous metal or gray amorphous powder. White light produces zirconia during combustion. Zirconium metal powder has certain dangerous characteristics. It is easy to burn under the condition of fine…

FeSiAl alloy powder

FeSiAl alloy powder powder is specifically a magnetic material that has a small coercive force and is easily magnetized and demagnetized. The so-called soft means that these materials are easily magnetized and appear "soft" in magnetic properties. Soft magnetic materials are used in a wide variety…

The Effects of Sintering Temperature on the Densification of Mechanically Alloyed W-Brass Composites

Prealloyed (PA) and premixed (PM) W-brass with the composition of 60 wt% W, 1 wt% Ni and 39 wt% brass was sintered at the temperature of 800°C, 920°C and 1000°C each. As a result of difficulties in the densification of W-Cu and W-Cu alloys, mechanical alloying (MA) and activated sintering were combi…

Mineral corundum

Corundum is a very hard, tough, and stable mineral. For all practical purposes, it is the hardest mineral after Diamond, making it the second hardest mineral. It is also unaffected by acids and most environments. Translucent brown Corundum and Emery are the most common forms of Corundum. These are f…

Bauxite supply situation

Calcined Bauxite is available as a wheel that serves its purpose in the construction industry. Calcined Bauxite is the principal ore of aluminum. Calcined Bauxite contains Hydrous aluminum oxides, formed through the laterization of aluminous rocks in tropical and subtropical areas. Calcined bauxite…
