Factory Supply Sodium aluminate price CAS 11138-49-1/1302-42-7 with high quality

Chemical Composition: Sodium aluminate consists of sodium ions (Na^+) and aluminate ions (AlO2^-) in a stoichiometric ratio. It is derived from the reaction between sodium hydroxide (NaOH) and aluminum oxide (Al2O3).

Production:

• Sodium aluminate is produced industrially by dissolving aluminum oxide (Al2O3) or hydrated aluminum hydroxide (Al(OH)3) in a solution of sodium hydroxide (NaOH).
• The reaction typically occurs at elevated temperatures and pressures to ensure the dissolution of aluminum compounds in the sodium hydroxide solution.
• The resulting sodium aluminate solution may be further processed, purified, or concentrated depending on its intended use.

Physical Properties:

• Appearance: Sodium aluminate is typically a white or grayish solid in the form of granules, powder, or solution.
• Solubility: It is soluble in water, forming an alkaline solution due to the presence of hydroxide ions (OH^-).
• pH: Sodium aluminate solutions are highly alkaline, with pH values typically ranging from 11 to 14, depending on the concentration.

Applications:

• Water Treatment: Sodium aluminate is used in water treatment processes, particularly in municipal and industrial wastewater treatment, for phosphorus removal. It forms insoluble aluminum hydroxide (Al(OH)3) precipitates with phosphate ions (PO4^3-) in the water, which are then removed by sedimentation or filtration.
• Paper Industry: It is employed in papermaking processes as a sizing agent or paper additive to improve paper strength, retention, and sizing efficiency.
• Catalysts: Sodium aluminate can serve as a catalyst or catalyst support in various chemical reactions, such as transesterification reactions in biodiesel production.
• Zeolite Synthesis: It is used as a precursor in the synthesis of zeolites, which are crystalline aluminosilicate minerals with diverse industrial applications, including adsorption, catalysis, and ion exchange.
• Specialty Chemicals: Sodium aluminate finds applications in the production of specialty chemicals, such as aluminates, aluminum salts, and aluminosilicates, used in diverse industries ranging from construction to automotive.

Safety Considerations:

• Sodium aluminate is generally regarded as safe when handled and used according to recommended guidelines.
• It is important to avoid direct contact with skin, eyes, and mucous membranes, as sodium aluminate solutions are highly alkaline and can cause irritation or burns.
• Proper handling practices, such as wearing protective clothing, gloves, and goggles, are recommended to minimize exposure and potential health hazards.

Environmental Impact:

• Sodium aluminate solutions should be handled and disposed of responsibly to prevent environmental contamination.
• Spills or releases of sodium aluminate should be contained, neutralized, and treated in accordance with local regulations to minimize their impact on soil, water, and aquatic ecosystems.
