Cobalt Acetate

Cobalt Acetate is a moderately water soluble crystalline Cobalt source that decomposes to Cobalt oxide on heating.Cobalt Acetate is a precursor to various oil drying agents, bleaching and drying varnishes and laquers, as a mineral supplement in animal feed, as a foam stabilizer for beverages and as a catalyst for oxidation.

Iron

Iron is a metal in the first transition series. It is the most common element in the whole planet Earth, forming much of Earth's outer and inner core, and it is the fourth most common element in the Earth's crust. Iron plays an important role in biology, forming complexes with molecular oxygen in hemoglobin and myoglobin; these two compounds are common oxygen transport proteins in vertebrates. It is also used at the active site of many important redox enzymes dealing with cellular respiration and oxidation and reduction in plants and animals. Iron is the most widely used of all the metals. It is used for the construction of machinery and machine tools, automobiles, the hulls of large ships, and structural components for buildings. Since pure iron is quite soft, it is most commonly used in the form of steel. Iron catalysts are traditionally used in the Haber-Bosch Process for the production of ammonia and the Fischer-Tropsch process for conversion of carbon monoxide to hydrocarbons for fuels and lubricants. Powdered iron in an acidic solvent was used in the Bechamp reduction the reduction of nitrobenzene to aniline. Iron(III) chloride finds use in water purification and sewage treatment, in the dyeing of cloth, as a coloring agent in paints, as an additive in animal feed, and as an etchant for copper in the manufacture of printed circuit boards. Iron(II) sulfate is used as a precursor to other iron compounds. It is also used to reduce chromate in cement. It is also used to fortify foods and treat iron deficiency anemia.

Nickel

Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt. Historically it has been used for plating metals such as iron and brass, for chemical apparatus, and in certain alloys such as German silver. It is still used for corrosion-resistant pure-nickel plating. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation. Enzymes of some microorganisms and plants contain nickel as an active center, which makes the metal an essential nutrient for them. It is used in many industrial and consumer products, including stainless steel, magnets, coinage, rechargeable batteries, electric guitar strings, microphone capsules, and special alloys.

Oxygen

Oxygen is a member of the chalcogen group on the periodic table, and is a highly reactive nonmetallic period 2 element that readily forms compounds with almost all other elements. It was independently discovered by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first. The name oxygen was coined in 1777 by Antoine Lavoisier, whose experiments with oxygen helped to discredit the popular phlogiston theory of combustion and corrosion. Uptake of oxygen from the air is the essential purpose of respiration, so oxygen supplementation is used in medicine. Treatment not only increases oxygen levels in the patient's blood, but has the secondary effect of decreasing resistance to blood flow in many types of diseased lungs, easing work load on the heart. Oxygen therapy is used to treat emphysema, pneumonia, some heart disorders, some disorders that cause increased pulmonary artery pressure, and any disease that impairs the body's ability to take up and use gaseous oxygen. Other uses of oxygen include the production of steel, plastics and textiles, rocket propellant, and life support in aircraft, submarines, spaceflight and diving.

copper

Reddish lustrous malleable odorless metallic solid.

Niobium

Niobium is a ductile transition metal. It is found in the minerals pyrochlore, the main commercial source for niobium, and columbite. It is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. The temperature stability of niobium-containing superalloys is important for its use in jet and rocket engines. Niobium is used in various superconducting materials. Other applications of niobium include its use in welding, nuclear industries, electronics, optics, numismatics and jewelry. In the last two applications, niobium's low toxicity and ability to be colored by anodization are particular advantages.

Chromium

Chromium was discovered by Louis Nicolas Vauquelin in the mineral crocoite in 1797. It was regarded with great interest because of its high corrosion resistance and hardness. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding chromium to form stainless steel. This application, along with chrome plating are currently the highest-volume uses of the metal. Chromium(III) salts are used in the tanning of leather. The high heat resistivity and high melting point makes chromite and chromium(III) oxide a material for high temperature refractory applications, like blast furnaces, cement kilns, molds for the firing of bricks and as foundry sands for the casting of metals. In these applications, the refractory materials are made from mixtures of chromite and magnesite. The use is declining because of the environmental regulations due to the possibility of the formation of chromium(VI).

Tantalum

Tantalum is a rare, hard, lustrous transition metal that is highly corrosion resistant. It is part of the refractory metals group, which are widely used as minor component in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum, but its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers. Tantalum, always together with the chemically similar niobium, occurs in the minerals tantalite, columbite and coltan.

Vanadium

Vanadium is a ductile transition metal. The element is found only in chemically combined form in nature. It is used as ferrovanadium or as a steel additive. Vanadium is compatible with iron and titanium, therefore vanadium foil is used in cladding titanium to steel.
