Description

Zirconium Sulfate CAS NO 14475-73-1 is an important inorganic zirconium salt widely used as a precursor and catalyst in industrial chemistry. Its primary value lies in its ability to provide a soluble source of zirconium ions, which are essential for precipitation, cross-linking, and catalytic processes. This compound is a critical raw material for manufacturers in the leather tanning, textile, catalyst, and specialty chemical synthesis industries.

Application

• Leather Tanning Agent: Used as a white tanning agent to produce high-quality, full-grained white leather with excellent thermal stability.
• Textile Mordant: Acts as a mordant in dyeing processes to improve color fastness and brightness on fabrics.
• Catalyst & Catalyst Support: Serves as a precursor for solid acid catalysts and as a support material in various organic synthesis and petroleum refining reactions.
• Precipitating Agent: Employed in water treatment and analytical chemistry for the precipitation of phosphates and other anions.
• Ceramics & Pigments: Used in the preparation of zirconia-based ceramics, opacifiers, and specialty inorganic pigments.
• Cross-linking Agent: Functions as a cross-linker for polymers, proteins, and starches to modify their physical properties.
• Paper Coating: Utilized in paper manufacturing to improve sheet strength, water resistance, and printability.
• Chemical Synthesis Intermediate: A key starting material for synthesizing other zirconium compounds, such as zirconium oxide and zirconium alkoxides.

Quality Control

Our Zirconium Sulfate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Production adheres to relevant industrial standards, with purity and impurity profiles controlled to meet specific application requirements. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metal content, and other critical parameters is provided with each shipment to guarantee product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking. Keep away from incompatible materials such as strong bases.
