Product Grades
Industrial Grade
Typically available at concentrations of 68% or 98%. Quality control primarily focuses on nitric acid content, residue on ignition, and conventional metal ions. Suitable for fertilizer production, metal pickling, and general chemical synthesis.
Reagent Grade
Concentration generally ranges from 65% to 68%, with further subdivisions into Guaranteed Reagent (GR), Analytical Reagent (AR), and Chemical Pure (CP). Among these, GR grade has the strictest impurity limits and is intended for precision analysis and high-purity synthesis.
Electronic Grade
Specifically designed for the semiconductor and photovoltaic industries. Classified by metal impurity content
● G1–G2 (ppm level) are used for photovoltaics and discrete devices;
● G3–G4 (ppb level) are applied in display panels and mid-tier chips;
● G5 (≤10 ppt, i.e., parts per trillion) represents the highest purity level, reserved for advanced semiconductor manufacturing processes.

Nitric Acid Used in the Agriculture Indudtry
Nitric acid is used in the production of nitrate nitrogen fertilizers and compound fertilizers such as ammonium nitrate, potassium nitrate, and nitrophosphate, providing crops with readily absorbable nitrate nitrogen.
Nitric Acid Used in the Chemical Manufacturing Industry
Nitric acid is an important raw material for synthesizing many chemicals, such as nitrobenzene, nitromethane, and nitrate salts, among others.
Nitric Acid Used in the Metalworking Industry
Nitric acid can react with metals and can be used for etching and removing oxide layers or impurities from metal surfaces. For example, nitric acid can be used to clean stainless steel, aluminum, copper, and other metals, leaving their surfaces smooth and bright.
Nitric Acid Used in the Electronic Industry
Nitric acid can be used in etching and corrosion processes within the electronics industry. For example, it can be used to etch copper foil on printed circuit boards (PCBs) to form conductive traces and components, thereby manufacturing electronic devices.
Nitric Acid Used in the Pharmaceutical Industry
Concentrated nitric acid serves as a key nitrating agent in the pharmaceutical industry, used in the synthesis of various antibiotics, central nervous system drugs, and other nitrogen-containing organic pharmaceutical raw materials.
Nitric Acid Used in the Glass Industry
Nitric acid can be used as a chemical agent in the glass manufacturing process. It can be used to remove impurities and oxides from the glass surface, improving the transparency and quality of the glass.
Nitric Acid Used in the Water Treatment Industry
Nitric acid is used in wastewater denitrification treatment and heavy metal digestion.
Nitric Acid Used in the Laboratory
Nitric acid is used as an analytical reagent for titration, sample pretreatment, and instrumental analysis.
