Aluminum Nitrate (CAS 13473-90-0) is a water-soluble, deliquescent oxidizing salt of aluminum that supplies aluminum ions in a controlled way, appearing as an odorless white crystalline solid, often handled as a liquid solution, and used in catalyst and ceramic production, textile dyeing mordants and specialty coating formulations. It appears as colorless crystals with strong hygroscopicity and is widely used in catalysis and materials chemistry.

Aluminum Nitrate
Applications
Applied in the manufacture of catalysts, ceramics, corrosion inhibitors, and specialty coatings. In textile dyeing, it acts as a mordant to improve color fixation. Laboratory-grade material is also employed in analytical reagents and synthesis of alumina powders.
Safety & Risks
An oxidizer that may intensify combustion in contact with organic matter. Irritating to eyes and skin; use chemical-resistant gloves, goggles, and avoid contact with combustibles.
Packaging
Supplied in HDPE-lined drums or bags. Store in a cool, dry area away from reducing agents and flammable materials, ensuring moisture protection.
