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…

Aluminum Hydroxide Gels and Powders

Aluminum hydroxide is a typical antacid active. It can be used alone or in combination with magnesium hydroxide to obtain the desired acid neutralizing capacity (ANC). Aluminum hydroxide as antacids are not just aluminum hydroxide (Al (OH) 3). Aluminum hydroxide gel is amorphous in nature and contai…

About of selenite

Selenite is the Greek word for moon, and refers to the crystals well-developed pearl-like luster that can reflect a soft moon-like glow.Alabaster is a common name used for particularly pure deposits of massive gypsum. In arid sandy areas, growing gypsum crystals may bind sand grains together into co…

Physical and Chemical Properties of Oxidized Graphite

Halogenated graphene derivatives are interesting owing to their outstanding physical and chemical properties. In this paper, we present various methods for the synthesis of iodinated graphene derivatives by the iodination of graphite oxides prepared according to either the Hummers or Hofmann method.…

How It colloidal silver works?

The presence of colloidal silver near a virus, fungus, bacterium or any other single celled pathogen disables its oxygen metabolism enzyme, its chemical lung, so to say. Within a few minutes, the pathogen suffocates and dies, and is cleared out of the body by the immune, lymphatic and elimination sy…

Will colloidal silver turn me blue?

Will Colloidal Silver Turn Me Blue?You may indeed turn bluish-grey if you ingest too much large-particle silver protein. This condition, called argyria, is not treatable or reversible and does not have any other known symptoms. Aside for argyria, excessive consumption of colloidal silver is said to…
