OUR PRODUCTS
FOR A WIDE RANGE OF APPLICATIONS
Partner of the industry
Our products are used in a wide range of industries.
Many of the refractory materials we process are used in the steel industry. But our refractory or extremely heat-resistant raw materials are also used in foundries or in the production of foundry aids. These properties are also used in furnace construction.
Other minerals are due to their composition and nature
– such as low sulphur and phosphorus content – particularly interesting for welding technology.
