Hafnium Metal is First Extracted D. Koster and Hervez, a Swedish chemist and physicist from the Netherlands, found hafnium among zircons in Greenland and Norway. The element was named Hafnium by the Latin name of Copenhagen. Hervis and Koster, in 1925, separated titanium and zirconium using the method of crystallization containing fluorosalts. They then reduced …
What does titanium nitride mean? Refractory compounds such as titanium nitride have high microhardness and are chemically and thermally stable. TiN is used as an ingredient in special refractory compounds and cermets. It also serves as a crucible substance for metal casting. TiN can also be used as a precursor for decorative and wear-resistant coatings. …
Zinc Sulfide ZnS Pulver Zinc sulfide The chemical formula ZnS is an inorganic compound. The powder can come in white or yellowish colors, as well as any combination. It darkens in sunlight. It can be stored dry. However, zinc sulfate will slowly oxidize when kept moist. This occurs when zinc sulfide reacts with zinc salt …
Gallium nitride An inorganic compound with the chemical name GaN. It is composed of both nitrogen and galium. Gallium nitride, a direct bandgap semiconductor, has been widely used in light emitting diodes (LEDs) since 1990. It has high hardness and a similar structure to wurtzite. The properties of Gallium Nickel: Gallium Nitride is a stable …
Calcium Nitride Properties Calcium nitride A compound made up of calcium and nitrogen. Ca3N2 is its chemical formula. It is a reddish-brown, crystalline liquid. Calcium nitride dissolves in water. It reacts with water to form calcium, and then releases ammonia. It is soluble in dilute acids and can be decomposed in alcohol. The heating of …
Metal 3D printing (or Selective Laser melting) is a process that direct prints metal parts using metal powder. The 3D-printed metal powders must not only have small particles and tight distribution. 3D printers are made of metal powders. You can choose from stainless steel, cobalt-chromium and nickel. One of the most precious and important metals …
Iron oxide, an inorganic compound with formula Fe2O3, is one example. This is the primary iron oxide. The other two are rare ferrousoxide (of FeO) and triiron troxide (of Fe3O4). Iron oxide can also be found naturally in the form of magnetite. Iron oxide can also be called hematite. This is the most important source …
Semiconductor Molybdenum disulfide Although graphene offers many amazing advantages, it has some disadvantages. One of these is its inability as a semiconductor. Material scientists, chemists, and material scientists have been trying to overcome graphene. The two-dimensional flake material is flexible and transparent and has electronic properties comparable to graphene. Molybdenum disulfide It is also one …
