25-01-2015· Alumina and Alumina Refractories. Alumina (Al2O3) refractories are the part of alumina- silica (SiO2) group of refractories and belongs to the SiO2 -Al2O3 phase equilibrium system as shown in diagram at Fig 1. They differs from fire clay refractories in term of Al2O3 content and normally have Al2O3 content of more than 45 %.
2.2 Sintering process The production of sintered high alumina aggregates such as tabular alumina and BSA96 follows the same process steps as practised in the advanced ceramics indus-try. In principle, they consist of raw mater-ial grinding, forming, drying and sintering. Initially, fine-crystalline alumina feedstock is ground in a ball mill.
