Chromium Oxide granules are inorganic compounds usually in the form of green granules with high hardness, high melting point and good chemical stability, which are widely used in metallurgy, ceramics, pigments, paints and other fields.
VIMATERIAL supplies Chromium Oxide granules, our granules have high purity, low impurities, uniform particles, controllable particle size and good chemical stability. We have been dedicated to the research of inorganic chemical raw materials for many years, we have a team of professionals with rich experience, accept customisation and experiments, please contact us if you need.
Molecular Formula: Cr₂O₃
Molecular weight: 151.99
Appearance: green granular, with metallic luster
Density: 5.22g/cm³
Melting point: 2435°C
Boiling point: 4000°C
Crystal structure: corundum type structure, belongs to the tripartite crystal system, space group R3c, consists of hexagonal densely stacked oxygen ion arrays and chromium ions occupying two thirds of the octahedral voids.
Metallurgy: Chromium Oxide particles are used as an alloying additive in the steelmaking process to improve the hardness, wear resistance and oxidation resistance of steel, helping to create high-strength mechanical parts and durable construction steel.
Ceramics: In ceramics, it is incorporated into the formulation of blanks and, thanks to its high-temperature resistance and chemical stability, it not only allows ceramics to withstand high firing temperatures, but also gives the finished product a brilliant and long-lasting colour, which is used in the manufacture of artistic ceramics and high-end tableware.
Pigments: As a key component of green pigments, Chromium Oxide granules are used in painting pigments, plastic colouring and architectural coatings for their outstanding colour saturation, light resistance and chemical inertness, ensuring long-lasting, brilliant colours.
Abrasives: With their high hardness, Chromium Oxide granules are used to make fine abrasives for polishing precision optical lenses and gemstone jewellery, achieving a highly efficient mirror finish without damaging the material.
Each batch of products follow strict quality control principles, all-round to ensure that each batch of materials from the procurement of raw materials, processing, finished goods out of the warehouse have advanced instruments, strict inspection standards, perfect inspection records to ensure product quality control and product traceability, each batch of products are accompanied by MSDS, COA, TDS, PSD, XRD reports, etc., each batch of products will be given to the customer to provide samples, also support the customer to request third-party inspection organisations. We will provide samples to customers for each batch of products and also support customers to request the third party inspection organisations to inspect the products.
Chromium Oxide granules are packed in double-layer vacuum bag or double-layer vacuum bottle and then packed in carton box.
Chromium Oxide granules should be stored in a dry, well-ventilated environment, away from fire and strong oxidising agents, to avoid moisture, and should be kept in sealed containers to prevent impurities from mixing in, to ensure that its chemical stability and physical properties are not affected.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
