Abstract
The present invention relates to a purification method for removing impurities containing oxygen from materials, especially boron, by hydrogen-based plasma treatment. The present procedure allows for efficient removal of oxygen while avoiding a thermal treatment that would substantially change the structure of the treated material, or a treatment leaving a reducing agent within the treated material.
