Refractory bauxite, also known as calcined bauxite, is produced by sintering raw bauxite at more than 1500 °C. This results in a high aluminium content and a low degree of impurity. As a result, calcined bauxite has a high aluminium content and a low degree of impurity, which makes this raw material particularly heat-resistant.
