White transparent crystal or powder (industrial products may be slightly yellow due to impurities). Tasteless or slightly sour. Soluble in cold water (about 10 g/100 mL, 20°C), with higher solubility in hot water. Slightly soluble in ethanol (approx. 5.7g /100 mL, 20°C).
Binaric acid with stronger acidity than acetic acid (pKa₁=1.25, pKa₂=4.14). Reacts with bases, metal oxides, and carbonates to form salts. Under acidic conditions can be oxidized by strong oxidants to produce CO₂ and H₂O. Forms soluble complexes with metal ions (e.g. Fe³+, Al³+), making it effective for metal cleaning and rust removal.
Over 20 years of experience in nitric acid production with stable quality products exceeding national standards, meeting requirements of rare earth, electronics, and reagent industries.
Complete industrial chain from nitric acid to potassium nitrate, magnesium nitrate, and nitro water-soluble fertilizer products. Strong extension capability with ongoing investment in high-purity nitrate and molten salt integration.
