Brown Fused Alumina also is known as BFA. It belongs to the group of electro-corundum. It is produced by smelting mixtures of calcined bauxite, iron and coke(anthracite) in an electric arc furnace at temperatures more than 2000°C. It’s a hard, tough, dense, fire-proof, sharp-edged, wear-resistant, and corrosion-resistant material. Brown Fused Alumina for Refractory is a mineral with good particle distribution for shaped and unshaped refractory products in fire-proof, precision casting, foundry and coating industries. Our Brown Fused Alumina Refractory Grades is a high-grade refractory material with high purity, high cleanness, coarse grain, low magnetic contents, high density, high bulk density, chemical stability, and low porosity rate, excellent crystal structure, corrosion and acid-resistant. It is widely used in the production of refractory bricks, steel making industry, ceramic, glass, cement industry etc.
Mohs hardness (according to Friedrich Mohs, 1773 – 1839) ascribes a relative hardness value to certain known minerals on a scale ranging from 1 (talc) to 10 (diamond). Accordingly, a mineral is considered harder than another if it can scratch the latter. Please note that these values merely form an
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
Yes, Sample cost below 5 kgs can be refunded when bulk order confirmed,But freight cost for more than 1kg don’t be refunded.
Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond for steel would be in the ‘F, G or H’ range. A
The specific weight is the ratio of the weight of a body to its volume. The specific weight of corundum under normal conditions is 3.94 g/cm3.
According to the FEPA, the bulk density of an abrasive is the quotient of the mass and the volume a grain type poured out in a particular manner will occupy. The bulk density, also called bulk weight, is stated in g/cm3. The rounder the particles, the higher the packing density,
