Buy nitric acid (HNO3, CAS 7697-37-2) from Alliance Chemical in 5%, 20%, 25%, 40%, 65%, 69%, and 70% options. Nitric acid is a strong mineral acid and oxidizer used for analytical digestion, stainless steel passivation, semiconductor processing, metal refining, etching, and chemical manufacturing.
Products In This Collection
This collection includes dilute nitric acid products for controlled handling and concentrated ACS or technical grades for reagent and production requirements. Available products may include low-particle or high-purity options for trace-metal and semiconductor workflows, plus technical grades for industrial surface treatment and pH control.
Common Applications
-
Analytical digestion: ACS nitric acid is used for sample digestion and trace-metal preparation where reagent purity and lot consistency matter.
-
Metal passivation and etching: Nitric acid helps remove free iron, prepare stainless steel, and support controlled metal surface treatment when specified.
-
Semiconductor and high-purity processing: High-purity nitric acid supports validated electronics cleaning and etching workflows where particles and metallic contamination are controlled.
-
Precious-metal refining: Nitric acid is used in selected refining and assay workflows, including processes that require controlled dissolution of metals.
Grade & Selection Notes
Choose dilute nitric acid when controlled reaction rate and safer handling are important. Choose ACS or low-particle grades for lab, QA, trace-metal, and semiconductor work. Choose technical grade only when the process specification allows industrial impurity limits.
Safety & Handling
Nitric acid is corrosive and oxidizing. It can produce toxic nitrogen oxides, react violently with organics and reducers, and cause severe burns. Use acid-resistant PPE, ventilation, secondary containment, compatible storage, and strict segregation from solvents, bases, metals, and combustible materials. Review the Safety Data Sheets before use and follow your site-specific handling procedure.
Why Buy From Alliance Chemical
Most in-stock nitric acid products ship with SDS support and lot documentation where applicable. Hazmat packaging, carrier method, and availability depend on concentration, package size, and destination.
