What is Aluminum nitrate nonahydrate?
Aluminum nitrate nonahydrate (CAS 7784-27-2) is a water-soluble aluminum salt in crystalline hydrated form.
Where is Aluminum nitrate nonahydrate used?
- Water treatment: coagulant and flocculant that destabilizes suspended solids and colloidal matter to clarify process and wastewater streams
- Textile and leather processing: mordant and tanning auxiliary improving dye fixation and surface treatment uniformity
- Pulp and paper manufacturing: supports retention aid systems and controls pH during wet-end chemistry
- Personal care: astringent and antiperspirant buffering properties in topical preparations
- It functions as a coagulant, corrosion inhibitor, and pH buffer.
Commercial specifications
- Purity typically ranging from technical to reagent grade
- Technical grade for industrial processing and higher-purity grades for laboratory and analytical requirements
- Packaging in bulk bags and smaller drum quantities
