A key part of the modern materials world in which zinc finds itself is recycling. A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate (as dietary supplements), zinc chloride (in deodorants), zinc pyrithione (anti-dandruff shampoos), zinc sulfide (in luminescent paints), and dimethylzinc or diethylzinc in the organic laboratory. Other applications are in electrical batteries, small non-structural castings, and alloys such as brass. The zinc protects iron by corroding first, but zinc corrodes at much lower rates than do steel. Galvanized steel is just plain carbon steel that has been coated with a thin zinc layer. Coating of steel constitutes the largest single use of zinc, but it is used in large tonnages in zinc alloy castings, as zinc dust and oxide, and in wrought zinc products. They are also used in paints, varnishes, and inks as “drying agents” through the oxidation of drying oils.Ĭorrosion-resistant zinc plating of iron (hot-dip galvanizing) is the major application for zinc. ![]() ![]() Typical catalysts are the cobalt carboxylates (known as cobalt soaps). Several cobalt compounds are oxidation catalysts. Moreover, they have excellent corrosion resistance at high temperatures (980-1100 ☌) because of their higher chromium contents. They possess better weldability and thermal fatigue resistance as compared to nickel based alloy. While not used commercially to the extent of Ni-based superalloys, alloying elements found in research Co-based alloys are C, Cr, W, Ni, Ti, Al, Ir, and Ta. Unlike other superalloys, cobalt-base alloys are characterized by a solid-solution-strengthened austenitic (fcc) matrix in which a small quantity of carbide is distributed. discovered a new phase in the Co–Al–W system. Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. Cobalt has been used in many industrial, commercial, and military applications. ![]()
