Fully Calcined Refractory Bauxite Grains GAL Low impurity content
High Bulk Density Grade Calcined Tunnel Kiln Bauxite 86% Refractories Bricks
1. Calcined Bauxite Introduction
Refractory bauxite, also known as calcined bauxite, is produced by sintering raw material 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.
