What is Aluminum nitrate?
Aluminum nitrate (CAS 13473-90-0), also called aluminium nitrate or aluminum trinitrate, is an inorganic aluminum salt used industrially as a coagulant, mordant and chemical intermediate.
Where is Aluminum nitrate used?
- Water treatment: coagulant that destabilizes suspended solids
- Municipal and industrial effluent systems: clarification by removing colloidal matter
- Textile and leather: mordant that fixes dyes onto fiber substrates, improving color fastness
- Pulp and paper: retention aid programs and pH regulation during wet-end chemistry
- Mining and metallurgy: chemical intermediate in alumina processing
- It also serves as a reagent in selective precipitation steps for extraction and purification.
Commercial specifications
- Purity specifications typically 98% to 99%+
- Bulk quantities in bags or drums
