New Tabular Alumina Castable
【Product brand】GC-18
【Recommended use】Kiln Outlet, Burner Pipe
Product Introduction
Main Performance Characteristics:
(1) The product uses high-density, high-melting-point tabular alumina as the primary raw material, providing excellent high-temperature performance.
(2) It exhibits good high-temperature alkali resistance, achieving a Grade II or above alkali resistance at 1350°C, addressing the issue of poor alkali erosion resistance in corundum-based castables.
(3) It possesses excellent thermal shock stability, preventing spalling or chunking during use.
