Selenium Dioxide

SELENIUM DIOXIDE imparts a red colour to glass. It is used in small quantities to counteract the colour due to iron impurities and so to create (apparently) colourless glass. In larger quantities, it gives a deep ruby red colour. It was also used as a toner in photographic developing. It is used for diseases of the heart and blood vessels, including stroke and “hardening of the arteries”.   It is offered in Technical and Laboratory Grade.  It is available in the form of Reddish brown Powder packed in 25kg, 50kg HDPE Bag. We can offer it in many grades as per the application needs in different industry sectors.
