RHI Magnesita N.V. is a supplier of refractory products, systems and services. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index. In 1908 Mining engineer Josef Hörhager discovered a magnesite deposit at Millstätter Alpe in Austria. A German American, Emil Winter, acquired the mining rights and founded the "Austro-American Magnesite Company" (later Radex Austria). In 1974 the company was bought by National Refractories Co. and in 1987 Radex-Heraklith Industriebeteiligungs AG ('RHI AG') emerged from the National Refractories Co. as a result of a management buyout. Then in 1991 RHI AG acquired Veitscher Magnesitwerke Actien-Gesellschaft, a rival business founded by Carl Spaeter in Germany in 1889. More information...
