brown aluminium oxide
with bauxite, carbonmaterial, iron filings as raw materials, brown fused alumina isrestored and obtained through the melting of the brown thebrownartificialcorunduminthe furnace above 2200 ℃, and made of a variety of particle sizesproducts by purifying, crystallization, sorting, crushing, magneticseparation and screening methods. with its dense texture, highhardness and the formation of spherical particles, it is suitablefor the manufacture of ceramics and resin, as well as thehigh-bonded abrasives grinding, polishing, sand blasting, precisioncasting and so on, also can be used to manufacture high-graderefractory material.
brown fused alumina hashigh purity, good crystalline li, low coefficient of linearexpansion, corrosion-resistant and other characteristics. dozens ofrefractory manufacturers have proved in practice that the producthas not detonate, non-powder, non-cracking characteristics in theapplication process.
particle size is inaccordance with international standards and can be processed asre universal size: no. f4 ~ f320, its chemicalcomposition varies depending on grain size. its prominent featureis the small crystal size, impact resistance and sphericalparticles. this product has high purity, dense texture, large bulkdensity, strong self-sharpening, good toughness, low level magneticmaterial content and other characteristics.
