Germany had earlier proposed existing of the structure of basic copper nitrate.With the development of automotive technology, car manufacturers in Japan, the United States and Europe have been using basic copper nitrate to take place of strontium nitrate as oxidizer of car safety airbag,Under the background of the biggest car safety airbag manufacturers in the world begin to use basic copper nitrate,we start to develop basic copper nitrate mass production process,and now this technology had taken shape.Later we found that different market  have different requirements of the product , such as in Europe the D50 particle size need less than 7 microns, but in Japan the size need less than 1.4 microns. So we later optimized the technology to developsuperfine basic copper nitrate about 0.9 microns,and addressing the separation and mass production of ultra-fine narrow particle size distribution.

 The company has applied for patent protection for the technology, and the patent application number: 201210082164.4
