Zinc

Zinc is a metallic chemical element. It is the 24th most abundant element in the Earth's crust and has five stable isotopes. Corrosion-resistant zinc plating of steel is the major application for zinc. Other applications are in batteries and alloys, such as brass. A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate as dietary supplements, zinc chloride in deodorants, zinc pyrithione in anti-dandruff shampoos, zinc sulfide in luminescent paints, and zinc methyl or zinc diethyl in the organic laboratory. Zinc oxide is widely used as a white pigment in paints, and as a catalyst in the manufacture of rubber. It is also used as a heat disperser for the rubber and acts to protect its polymers from ultraviolet radiation. The semiconductor properties of zinc oxide make it useful in varistors and photocopying products.

Zinc Bromide

Zinc Bromide is a inorganic compound. It is used in organic chemistry as a Lewis acid. It is the electrolyte in the zinc bromide battery. In oil and natural gas wells, solutions containing zinc bromide are used to displacing drilling mud when transistioning from the drilling phase to the completion phase or in well workover operations. Zinc bromide solutions can be used as a transparent shield against radiation. Two glass panes filled with a strong aqueous solution of zinc bromide has a very high density, which can then be used as a window on a hot cell. This type of window has the advantage over lead glass in that it will not darken as a result of exposure to radiation. All glass will darken slowly over time due to radiation, however this is especially true in a hot cell, where exceptional levels of radiation are present. The advantage of an aqueous salt solution is that any radiation damage will last less than a millisecond, so the shield will undergo self-repair.

Zinc Chromate

Zinc chromate is a chemical compound containing the chromate anion. It is used industrially in chromate conversion coatings. Its use as a corrosion resistant agent was applied to aluminium alloy parts first in commercial aircraft, and then in military ones. It is highly toxic and rarely used in art anymore.

Zinc Dialkyldithiophosphates

Zinc dialkyldithiophosphates are a family of coordination compounds invented by Castrol that feature zinc bound to the anion of dithiophosphoric acid. These uncharged compounds are not salts. They are soluble in nonpolar solvents, and the longer chain derivatives easily dissolve in mineral and synthetic oils used as lubricants. The main use of ZDDP is in anti-wear additives to lubricants such as greases, gear oils, and motor oils. It serve also as corrosion inhibitors and antioxidants.

Properties Suppliers
Zinc Dithiophosphate

The main use of zinc dithiophosphate is in anti-wear additives to lubricants such as greases, gear oils, and motor oils, which contain about 1%. For applications in oils for gasoline engines, zinc and phosphorus emissions could damage catalytic converters and have had their quantity reduced in standard formulations. The same compounds serve also as corrosion inhibitors and antioxidants.

Zinc Iodide

Zinc iodide is a chemical compound of zinc and iodine. It is often used as an x-ray opaque penetrant in industrial radiography to improve the contrast between the damage and intact composite. United States Patent 4109065 describes a rechargeable aqueous zinc-halogen cell which includes an aqueous electrolytic solution containing a zinc salt selected from the class consisting of zinc bromide, zinc iodide, and mixtures thereof, in both positive and negative electrode compartments. In conjunction with osmium tetroxide zinc iodide is used as a stain in electron microscopy.

Zinc Phosphide

Zinc Phosphide is an inorganic chemical compound. Zinc phosphide can be prepared by the reaction of zinc with phosphorus. Zinc phosphide was first registered for use as a pesticide in the United States by the U.S. Department of Agriculture (USDA) in 1947. Zinc phosphide converts to phosphine gas in the presence of moisture and acid in the stomach.It will be used as an additional vertebrate poison in certain situations.

Properties Suppliers
Zinc Sulfate

Zinc sulfate is the inorganic compound.It is used to supply zinc in animal feeds, fertilizers, and agricultural sprays,in making lithopone,in coagulation baths for rayon,in electrolyte for zinc plating,as a mordant in dyeing,as a preservative for skins and leather,and in medicine as an astringent and emitic.It is used as a catalyst in numerous chemical operations. In water treatment, Zinc Sulfate finds application as a corrosion inhibitor in cooling towers and municipal water systems. Zinc Sulfate also finds use in production of pigments, preservation and clarification of glue, in flame proofing compounds, as a mining flotation agent, in wood preservatives, in electro metallurgy and electro galvanizing.
