Chromium Pieces Industrial Grade 99.9%

Chromium pieces are mainly for smelting. Two purity are available, 99% and 99.8%. It could be in other shapes too as lumps, ingots, sheets, rods, granules, wires and so on. Chromium is silvery white metal, which is hard and brittle. It is inactive metal and stable to oxygen and moisture at room temperature. Chromium pieces is of irregular small lumps. 99.99% and 99.95% Cr is product by hydrogen reduction process. 99.5%-99.8% Cr is product by carbon reduction process.

Chromium Pieces

CAS No.: 7440-47-3 EINECS No.: 231-157-5 Molecular Formula: Cr Molecular Weight: 52
Melting Point: 1857℃ Boiling Point: 2672℃ Melting Heat: 1.53*104J/mol Vaporization Heat:2.99*105J/mol

Applications

Chromium metal is mainly for hard alloys, diamond tools, welding materials, stainless steel, targets, vacuuming coating, thermal spraying and ceramics.

Chrome ingots apply to tough malleable steel, stainless steel and acid proof alloy. Pure chromium can apply to electroplate.  It is raw material for high temperature alloys, electro-resistance alloys and precision alloys. It can improve hardness and corrosion resistance in alloy steels. In non-ferrous alloys, chromium lumps can improve high-temperature strength, fracture resistance, corrosion resistance and antioxidant.

Chromium Trioxide

Chromium trioxide is the acidic anhydride of chromic acid. It is mainly used in chrome-plating. Typically it is employed with additives that affect the plating process but do not react with the trioxide. The trioxide reacts with cadmium, zinc, and other metals to generate passivating chromate films that resist corrosion.

Citric Acid

Citric acid is a weak organic acid. It is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of virtually all living things. It can also be used as an environmentally benign cleaning agent. Citric acid's ability to chelate metals makes it useful in soaps and laundry detergents. Ash rocks and citric acid are used in biotechnology and the pharmaceutical industry to passivate high-purity process piping. It is commonly used as a buffer to increase the solubility of brown heroin. Single-use citric acid sachets have been used as an inducement to get heroin users to exchange their dirty needles for clean needles in an attempt to decrease the spread of AIDS and hepatitis. Citric acid is used as one of the active ingredients in the production of anti-viral tissues. As a food additive, citric acid is used as a flavoring and preservative in food and beverages. It is used as a successful alternative to nitric acid in passivation of stainless steel. It can be used to slow setting of Portland cement. It can delay setting time substantially. It is also used as a stop bath as part of the process for developing photographic film.
