The company has developed industrial production processes for various materials such as high-purity tellurium (4N-7N), high-purity antimony (4N-7N), high-purity cadmium (5N-7N), high-purity zinc (5N-7N), high-purity gallium (5N-7N), high-purity bismuth (5N-6N), high-purity indium (5N-7N), and high-purity selenium (4N-6N) through technological innovation, and is in a leading position in China.While significantly increasing the production of high-purity materials per unit, the product quality has been steadily improved, ushering in a new stage of industrial production of high-purity materials. We will strive to become the largest high-purity material production base in China.
