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).
E-Brite CR is a bright decorative hexavalent chrome plating process that can be used on a wide range of parts and equipment.
Chromic Acid hexavalent chromium compound and a powerful oxidizing agent.It is an intermediate in chromium plating, metal finishing and is also used in ceramic glazes, and colored glass. It can be used to clean laboratory glassware,in magnetic recording tapes,wood preservation.Chromic acid is used in the anodizing of aluminum,used to produce salt-free CCA type wood preservatives.
Coldip TRI-V is extremely economical, single component process; produces attractive bright-blue trivalent chromate coatings. It is suitable for both rack and barrel applications where appearance is important and extended corrosion resistance is not required.
Sodium metabisulphite is marketed under the brand ASA IMPEX (ASA).
SMBS is used as a preservative in the starch and food industry to control melanosis (black spot) in shrimp; for fermentation in the industry; as an antichlor in the chemical industry and as a redox catalyst in the acrylic fibre industry.
The product is also used as a reducing agent in the purification of aldehydes and ketones; in the manufacture of sulphonated oil and resin; for detoxification of cyanide in gold ore processing plants and in the manufacture of photographic chemicals.
Sodium metabisulphite is manufactured by ASA IMPEX (India).

Bt-116 is an environmental protection chromium mist inhibitor which is a kind of highly effective fluorocarbon surfactant without PFOS series. It has good high temperature resistance, oxidation resistance and electrolytic stability in the production process of chromium electroplating. It can effectively reduce the concentration of chromic acid in electroplating workshop. Moreover, it can inhibit
the volatilization of acid mist, improve the working environment in the electroplating workshop and reduce the cost.
