For professionals in industries ranging from water treatment to papermaking, a thorough understanding of the chemicals they utilize is essential. Aluminum sulfate, identified by its CAS number 10043-01-3, is a fundamental industrial chemical with a distinct set of properties that dictate its efficacy in various applications. As a specialized chemical manufacturer and supplier, we provide insights into these critical characteristics to aid your procurement and application decisions.

Aluminum sulfate, with the chemical formula Al₂(SO₄)₃, is an inorganic salt that typically appears as a white crystalline solid, powder, or granules. It is known for its hygroscopic nature, meaning it readily absorbs moisture from the air, which can lead to caking if not stored properly. This characteristic necessitates storage in cool, dry, and well-ventilated environments.

Key chemical and physical properties of aluminum sulfate (CAS 10043-01-3) relevant to industrial users include:

  • Solubility: Highly soluble in water, forming an acidic solution due to hydrolysis. This acidity is a functional property in applications like pH adjustment and papermaking.
  • Melting Point: While the anhydrous form decomposes at high temperatures (around 770°C), hydrates will melt at much lower temperatures.
  • Density: Typically around 2.71 g/cm³ for the anhydrous form.
  • Appearance: Commonly white or off-white, with potential slight coloration from impurities like iron, hence the importance of non-ferric grades.
  • Acidity: Its aqueous solutions are acidic, with a pH typically ranging from 2.0 to 3.5 for a 1% solution.
  • Reactivity: Acts as a coagulant, precipitant, and mordant due to its aluminum ions, which readily form hydroxide precipitates and complexes with other substances.

Understanding these properties is crucial for optimizing dosage, handling, storage, and overall performance in applications like flocculation in water treatment, sizing in paper mills, and color fixing in textiles.
