CHROME PIGMENTS

Chrome Oxide Green, also known as Chromium Oxide (Cr₂O₃), is a highly versatile pigment recognized for its exceptional opacity, durability, and resistance to heat and chemicals. Classified as Pigment Green 17 (C.I. 77288) in the Colour Index, this crystalline green powder is insoluble in water, acids, and alkalis. Its robustness makes it ideal for a wide range of applications. In the pigment industry, it is used in porcelain, ceramic glazes, plastics, frits, and as a base for producing other metal oxide pigments. In construction, it provides vibrant and durable color for cements, roofing tiles, linoleum, and concrete products. It is also widely employed in industrial coatings, paints, and inks for its excellent stability. Chrome Oxide Green is an essential component in colored glass, refractory bricks, aerospace super-alloys, and stainless steel electrodes. Additionally, it serves as a catalyst in the chemical industry and is valued for its hardness in polishing and surface finishing applications. This pigment's versatility and performance make it indispensable across multiple industries. 

  Chrome Yellow, also known as Lead Chrome Yellow, is an inorganic pigment derived by adding lead nitrate or lead acetate to a solution of alkali chromate or dichromate. Composed of crystalline lead chromate, its hue can range from light yellow to deep yellow depending on the particle size, which is influenced by the conditions of precipitation. Lighter shades, such as light chrome yellow, often contain lead sulfate or other insoluble lead salts, while middle shades are composed of neutral lead chromate, and orange chromes are based on basic lead chromate. This pigment consists of fine, dense, and opaque particles, offering a variety of shades, including light chrome yellow, lemon chrome yellow, medium chrome yellow, orange chrome yellow, deep chrome yellow, and zinc chrome yellow. 

  Molybdate Orange, also known as Molybdate Red, is a vibrant pigment created through the coprecipitation of lead chromate and lead molybdate, often with lead sulfate to enhance stability and modify its hue. Classified as Pigment Red 104 (C.I. 77605) by the Color Index System, it offers brilliant orange to reddish-orange shades with exceptional tinting strength, opacity, and durability. This pigment has been widely used in coatings, plastics, and printing inks due to its bright color and high hiding power, making it ideal for industrial, automotive, and decorative applications. Occasionally, it is also employed in construction materials like colored cement. However, its use has become restricted in many countries because of the environmental and health risks associated with its lead and chromium content. Despite these limitations, Molybdate Orange remains valued for its unique properties in niche applications where alternatives cannot achieve similar brightness and performance.
