These Albawhite® types are super white, easily dispersible natural barium sulphate extenders. At the production site of Deutsche Baryt-Industrie in Bad Lauterberg in the Harz mountains, the sorted raw material is well finished by milling in a modern type of jet mill. Two different products are available with best cost effectiveness and extraordinary quality. Very important is the low particle size (gloss) and the high brightness as well as the low Si-content of the products, and therefore the high profitability in maintenance costs for the customer.
