brown fused alumina tempered in brazil

Fused Aluminas - an overview | ScienceDirect Topics

Brown fused alumina is made from bauxite ore under conditions that allow the partial removal of impurities as ferrosilicon. The impurities left lower its melting temperature by about 50°C and it is used commonly, e.g., in refractories for blast furnace trough and induction furnace linings.

Bauxite - an overview | ScienceDirect Topics

Alumina is unaffected by gases, except fluorine, and it stands up well to fused alkalies. The most usual shapes made are tubes and crucibles. “Alundum” cement is a useful mixture of fused alumina and clay which can be tempered with water and hand-moulded to any shape for laboratory use.

Borosilie glass - Wikipedia

Borosilie glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilie glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal
