Dense Shaped Refractory products
Refractory bricks have specific shapes and are in majority fired at high temperatures to form a ceramic bond. The raw material mixture, type of compaction and the heat treatment determine the final properties of dense shaped refractory materials.
More than 50% of all shaped refractory products can be allocated in a chemical / mineralogical sense to the binary system SiO2 - Al2 O3 . In general, with increasing Al2 O3 content also the refractoriness and maximum application temperature of the brick increases. But, depending on the raw materials used, accompanying substances (impurities) such as Fe2 O3 , TiO2 , alkalies, earth alkalies can have a significant influence on the final properties by the formation of low melting phases.
Synthetic high alumina materials provide stable chemical compositions with low amount of impurities and allow the formulation of high performing refractory bricks with reliable properties.
