Description

Sodium Aluminate is an important inorganic chemical compound widely used as a versatile source of aluminate ions. This material is valued for its strong alkalinity and effectiveness as a precipitating and coagulating agent in numerous industrial processes. Key industries that rely on Sodium Aluminate CAS NO 1302-42-7 include water treatment, paper manufacturing, and construction.

Application

• Water & Wastewater Treatment: Acts as a primary coagulant and precipitant for removing phosphates, fluorides, and suspended solids.
• Paper Industry: Used as a sizing agent to improve water resistance and printability of paper products.
• Construction & Cement: Functions as an accelerator in concrete setting and is a key component in some refractory cements.
• Catalyst & Zeolite Manufacturing: Serves as a crucial raw material (alumina source) in the synthesis of catalysts and molecular sieves.
• Textile Processing: Employed as a mordant in dyeing processes to improve color fastness.
• Soap & Detergent Manufacturing: Utilized as a builder to enhance cleaning efficiency and water softening.

Quality Control

Our Sodium Aluminate is manufactured under strict quality protocols to ensure batch-to-batch consistency and performance. Production adheres to relevant industrial standards, and each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, alkalinity, and impurity levels. We are committed to meeting the specific quality requirements of our global B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Separate from strong acids and incompatible materials.
