Aluminum Sulfate (CAS 10043-01-3), a white crystalline solid or powder, is a foundational chemical compound with a broad spectrum of industrial applications. Its efficacy stems from a unique set of chemical properties that make it indispensable in sectors such as water treatment, papermaking, textiles, and construction. As a B2B supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers high-purity, industrial-grade Aluminum Sulfate, providing vital solutions for manufacturers and treatment facilities. Understanding its chemical characteristics is key to leveraging its full potential.

Key Chemical Properties of Aluminum Sulfate:

• Chemical Formula and Structure: Al2(SO4)3. It is an aluminum salt of sulfuric acid.
• Purity: Industrial grades typically contain 16%-17% Al2O3, with low levels of impurities like iron (≤0.005%) and insoluble matter (≤0.1%).
• Appearance: Commonly found as a white crystalline solid, powder, or granules.
• Solubility: Soluble in cold water and freely soluble in hot water, forming acidic solutions due to hydrolysis.
• pH Value: A 1% aqueous solution typically has a pH between 3.0 and 3.5, indicating its acidic nature.
• Melting Point/Decomposition: The anhydrous form decomposes around 770 °C. Hydrates have lower melting points.
• Hygroscopic Nature: It readily absorbs moisture from the air, making proper storage crucial to prevent caking.

Industrial Applications Driven by Chemical Properties:

The specific chemical properties of Aluminum Sulfate dictate its wide-ranging industrial uses:

• Water Treatment: Its acidic hydrolysis and the formation of aluminum hydroxide precipitate (Al(OH)3) make it an excellent coagulant. This precipitate effectively traps suspended solids, organic matter, and heavy metals, clarifying water. We supply high-purity Aluminum Sulfate specifically for drinking water treatment, ensuring safety and compliance.
• Papermaking: As a sizing agent, it works with rosin to control ink and water absorption in paper, improving quality and printability. Its pH buffering capacity is also beneficial in neutral and alkaline papermaking processes.
• Textile Industry: Its ability to form insoluble complexes with dyes makes it an effective mordant, enhancing color fastness and durability in dyed fabrics.
• Construction: Incorporated into concrete mixes, it acts as an accelerator and waterproofing agent, contributing to faster setting times and increased durability.
• Agriculture: Used to lower soil pH, which is beneficial for acid-loving plants like hydrangeas, influencing flower color.
• Other Uses: Its applications also include fire retardants, deodorizers, catalysts, and in the tanning of leather.
