13N ultra-high purity germanium single crystal is coming! Guangzhi Science and Technology Historic Breakthrough shares rose more than 7% [SMM Express]

Guangzhi shares opened higher today, rising more than 7 per cent as of around 13:25.

It is reported that recently, Anhui Guangzhi Science and Technology Co., Ltd. (referred to as "Guangzhi Technology") successfully developed 13N (99.99999999999%) ultra-high purity germanium single crystal, breaking through the long-term blockade and monopoly of ultra-high purity germanium abroad. At present, Guangzhi Science and Technology has advanced R & D equipment such as automatic single crystal growth furnace, has mastered the key technology of preparing ultra-high purity germanium single crystal, solved the problem of neck jam, and filled the domestic blank in this field. and has built an international advanced level of ultra-high purity germanium production line, can supply high-quality 13N ultra-high purity germanium single crystal to global customers.

Ultra-high purity germanium single crystal material is the most high-end and most difficult material in the series of germanium products, with a purity of 13N, which is the core material for the manufacture of high-purity germanium detectors. The performance of detector-grade germanium single crystal is stringent, and its growth and preparation process is extremely difficult. at present, only the United States and Belgium can produce ultra-high purity germanium single crystal, and the main producers are Umicore, Ametek and Canberra (Mirion). China leads the world in the output of metal germanium, but the technology in the field of germanium deep processing is relatively weak, so the research and development of ultra-high purity germanium single crystal is the general trend of the development of national germanium industry.
