Alumina and Alumina Refractories – IspatGuru

Bauxite is a rock which consists largely of alumina hydrates and usually contain impurities such as iron and titanium oxides. Only bauxite with a high Al2O3 content and low iron oxide content is suitable for refractory purposes. Since bauxites give away their water during heating accompanied by a marked reduction in volume, they are generally sintered. During this sintering, corundum and mullite are

Merits of using andalusite-based refractories compared to

Historically bauxite-based refractories have been used in applications where andalusite-based refractories could work. Bauxite-based refractories were chosen over andalusite-based refractories mainly because of the availability of low-cost Chinese bauxite and also because many furnaces were designed by international companies

Refractories: Properties and Types | Engineering

It is a double carbonate of calcium and magnesium and occurs abundantly in India. It is burnt generally in shaft furnaces. Dolomitic bricks have low conductivity and refractoriness as compared to magnesite bricks. Calcium oxide present in the bricks has a tendency to combine with water and carbon dioxide present in the atmosphere, and causes disintegration of the bricks. They are cheaper than magnesite
