Chemical Composition And Properties Of BFA

The unique physical and chemical properties of BFA make it an ideal material for various high-temperature applications. It has excellent refractoriness, which allows it to withstand temperatures above 2200°C. It is also resistant to acid, alkali, and corrosion, which makes it ideal for use in furnace walls and roofs where it can protect the furnace from corrosion and high-temperature damage. BFA's excellent thermal insulation and fire retardant properties also make it an excellent material for use in corundum insulation materials.

BFA's chemical composition is relatively uniform, with a minimum content of 6-10% SiO2, 5-8% Al2O3, 1-2% TiO2, and 1-4% CaO. The content of MgO and Cr2O3 can be adjusted according to the intended use. BFA's grain size and refractoriness also vary, depending on the intended use and the process used for manufacturing.
