          [Appearance] light yellow, transparent liquid.
          [Physicochemical characteristics]
          The specific gravity is 1.498-1.506 when the temperature is 20°C. It is strong oxidizer, a kind of strong acid with strong causticity. It is easy to be decompounded when heated.
          [Main use] used in medicine, dye, photo material, and in many other processes of manufacture of organic chemicals. It is also one of the important materials of explosive industry.
          [Technical requirements] In accordance with requirements of the following table:

          [Packaging]Packed in aluminum pot or gallipot.
          [Safety requirement]
          For its strong oxidizer, it should not be touched by organic substance. For its strong causticity, protective articles should be worn. The fire caused by nitric acid (cone) should be extinguished by sandy soil, carbon dioxide and washed by large amount of water. At the same time, toxicosis of nitrogen oxide should be avoided.
