In petrochemical plants and refineries, special refractory products are used more frequently than standard classical refractory materials. In addition to low alumina high silicon dioxide bricks with acidic character very special corundum based bricks with 90-99% alumina content is needed. These bricks have high performance. Hence, the refractory consumption speed in these sectors is slow and the consumption rate is very low. With its qualified products, Haznedar promptly responds to the needs of such sectors which require a wide range of refractory materials.
