The industrialization of high-abundance boron-11 isotopes was successful

At the end of December 2022, the 1000 kg/year electronic-grade high-abundance boron-11 isotope production process led by Shanghai Research Institute of Chemical Industry was successfully applied in Shandong Heyi Gas Co.
, Ltd.
, and boron trifluoride-11 products
with an abundance of more than 99.
9% were obtained.

The project uses anisole chemical exchange method to produce boron-11 isotope, which is another isotope product after the successful development and industrialization of isotopes hydrogen-2, nitrogen-15, neon-22, oxygen-18 and carbon-13 by Shanghai Research Institute of Chemical Industry, marking another important breakthrough
in the field of isotope separation of precision distillation technology of Shanghai Research Institute of Chemical Industry.

Shanghai Research Institute of Chemical Industry and Shandong Heyi Gas Co.
, Ltd.
signed a cooperation agreement in January 2020 to carry out scientific research on the project; Completed the pilot test in September 2021; Construction of production units started in March 2022; In October 022, it entered the trial production stage, achieved a successful one-time start-up, and all the key process parameters of the project device reached the indicators
.
At present, the project team is further optimizing and upgrading product quality and exerting equipment capacity to lay a solid foundation for
large-scale production.

It is reported that high-abundance boron trifluoride-11 is an important special gas material in the manufacture of high-end chips, panels and other products, compared with ordinary abundance boron trifluoride doping, it can significantly improve the stability and anti-interference ability of chips, and is used in communications, aerospace and other fields
.
Before the Shanghai Research Institute of Chemical Industry achieved a technological breakthrough, only the United States and Georgia had 3 sets of production units for this product, and China's related technologies and products were completely dependent on imports
