Nitric acid molecular formula HNO₃, main use: Nitric acid is one of the important products in the basic inorganic chemical industry, and is an important raw material for the manufacture of fertilizers, dyes, medicines, photographic materials, plastics, synthetic fibers, electronic manufacturing and explosives. In the non-ferrous metallurgical industry, it is used to refine metals.

The nitric acid product produced by Huachang Chemical is produced by the oxidation reaction of ammonia and air as raw materials to generate nitric oxide, nitric oxide is oxidized to nitrogen dioxide, and nitrogen dioxide is obtained by absorption of desalinated water. The national standard GB/T337.1-2014 " Industrial Nitric Acid Concentrated Nitric Acid", GB/T337.2-2014 "Industrial Nitric Acid Dilute Nitric Acid". Among them, the quality indicators of dilute nitric acid 62 are: concentration ≥ 62%, nitrous acid ≤ 0.010%, ignition residue ≤ 0.01%. The quality indicators of dilute nitric acid 68 are: concentration ≥ 68%, nitrous acid ≤ 0.010%, burning residue ≤ 0.01%. Concentrated nitric acid 98 quality indicators are: concentration ≥ 98%, nitrous acid ≤ 0.50%, ignition residue ≤ 0.02%.

Packing method: stainless steel storage tank for dilute nitric acid, aluminum storage tank for concentrated nitric acid.
