Chromium Trioxide, also known as chromic anhydride, is a vital chromium compound widely used in numerous industrial applications due to its excellent oxidizing properties and high purity. Produced under strict quality control standards by Foshan Brilliance Chemical Co., Ltd., our Chromium Trioxide meets international specifications, making it ideal for electroplating, chemical synthesis, dyeing, and catalyst manufacturing. As a leading chemical manufacturer and supplier, Brilliance Chemical provides stable, high-quality Chromium Trioxide that supports diverse industries worldwide.
Chromium Trioxide is primarily used as the raw material for chromium plating in the electroplating industry. It is essential in producing chromium plating solutions for bicycles, sewing machines, watches, meters, torches, and various daily-use hardware. Its role extends to manufacturing high-purity chromium metal and chromium oxide green pigments. Additionally, chromium trioxide is crucial for producing zinc chromium yellow pigments, which find applications in coatings and plastics.
This compound serves as a fundamental raw material for producing catalysts, including low-temperature transformation catalysts, high-temperature transformation catalysts, and high-pressure methanol synthesis catalysts. Notably, it acts as the catalyst for medium-pressure polyethylene production through the Phillips method, highlighting its significance in polymer industry advancements.
Chromium Trioxide is widely utilized as a mordant in dyeing wool fabrics, improving color fastness and dye adherence. In the printing and dyeing industry, it functions as a strong oxidizing agent, facilitating fabric treatment processes. Its mordant properties also extend to the tanning industry, assisting in leather processing and enhancing product quality.
Beyond textiles and catalysis, chromium trioxide is used for wood preservation, providing durable protection against decay and pests. In galvanizing passivation, it forms the essential passivation film on zinc plating layers, preventing corrosion and extending the lifespan of coated metals. It also acts as an oxidant in the chemical oxidation of aluminum and its alloys, crucial for anodizing and protective film formation.
