Product Description

Product Description:


Brown Fused Alumina (BFA) is a highly advanced refractory material that is produced by melting bauxite in an electric arc furnace at high temperatures. This results in a brownish-colored product with exceptional hardness and toughness.


One of the main reasons for the popularity of BFA is its high purity and good crystal structure. The product also has strong fluidity, low coefficient of linear expansion, and corrosion resistance, further enhancing its value as a refractory material.




Brown corundum is a highly sought after material due to its numerous advantageous properties. It boasts an impressive MOH hardness of 9.0, second only to diamond, making it exceptionally tough and resistant to wear.


In addition to its hardness, this mineral also possesses high chemical stability and corrosion resistance. It is able to withstand harsh environments, including acids, alkalis, and high temperatures, without experiencing any adverse effects.
