Physical Appearance: White crystalline solid or powder, odorless, highly soluble in water.
Molecular Weight: 375.13 g/mol (nonahydrate), 212.99 g/mol (anhydrous).
Density: 1.72 g/cm³ (nonahydrate).
Melting Point: ~73°C (nonahydrate).
pH (aqueous solution): 2.5–3.5 (at 25°C, 50 g/L).
Applications
Analytical Reagent: Used in laboratories for precise chemical analyses and experiments where purity is essential.
Catalyst Precursor: Serves as a starting material for many catalysts and complex salts in material science.
Preparation of Alumina: Used for synthesizing aluminium oxide (Al₂O₃) in ceramics, catalysts, and refractory products.
Leather Tanning and Textile Processing: Acts as a strong oxidizing agent in tanning and textile finishing.
Corrosion Inhibitor: Applied in surface treatment and as an additive to inhibit corrosion of metals.
Antiperspirants and Pharmaceuticals: Utilized in manufacture of personal care and some medical products.
Extraction of Uranium and Actinides: Used in hydrometallurgical processes for extraction and purification due to strong oxidizing properties.
Nitrating Agent: Suitable for organic synthesis requiring robust nitration.
Specification for Extra Pure Grade
Purity: Typically ≥98%, with trace metals (Fe, Ca, Mg, K, Na, heavy metals) controlled below 0.001–0.005%.
Contaminants: Chloride and sulfate content usually less than 0.001–0.005%.
Shelf Life: Around 60 months if stored away from moisture and contaminants.
Aluminium nitrate extra pure is valued for its strong oxidizing abilities, high solubility, and suitability in demanding analytical, manufacturing, and research processes
