Description

Chromium Hydroxide is an inorganic compound primarily recognized for its role as a key intermediate in the production of chromium-based pigments and catalysts. Its controlled precipitation and purity are critical for achieving consistent color properties and catalytic activity in downstream industrial processes. This material is essential for manufacturers in the pigment, ceramics, catalyst, and wastewater treatment industries seeking a reliable source of high-quality chromium compounds.

Application

• Pigment Manufacturing: Serves as a crucial precursor for the synthesis of various green chromium oxide pigments used in paints, plastics, and ceramics.
• Catalyst Production: Used in the preparation of supported chromium catalysts for polymerization and other organic synthesis reactions.
• Ceramics & Glass: Imparts green coloration in ceramic glazes and specialty glass formulations.
• Wastewater Treatment: Acts as an adsorbent and coagulant aid for the removal of heavy metals and other contaminants from industrial effluent.
• Leather Tanning: Employed in certain chrome tanning processes for leather production.
• Research & Development: Used as a starting material or reagent in chemical synthesis and materials science research.

Quality Control

Our Chromium Hydroxide is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including assay, impurity profiling, and physical characterization. A Certificate of Analysis (COA) detailing specific results is provided with each shipment to guarantee compliance with agreed specifications and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids. The product is hygroscopic (moisture-sensitive) and should be kept under conditions that minimize exposure to atmospheric humidity to prevent caking or degradation.
