We supply our selenium products to glass manufacturers worldwide

The worldwide production of glass is accounting for about 50% of consumption in selenium compounds. Selenium metal powder, selenium metal pellets, zinc selenite, or sodium selenite are required for the most diverse manufacturing processes in the glass industry. Selenium is an essential part in the recycling of glass, as it serves to decolorize the glass mass. We also provide selenium compounds in a purity grade of at least 99.5% up to 99,95% suitable for technical applications like the production of optically highly re-flective surfaces to windows.
