antimony trioxide production process

Eliminating arsenic impurities from high-purity antimony trioxide

The production of high-purity antimony trioxide (Sb 2 O 3) in this study involves the removal of arsenic (As) from Sb 2 O 3 using the sulfurization precipitation method. This method is pivotal in reducing the As content to as low as 0.1 ppm, showcasing its efficiency and potential for broader industrial applications.
