White Fused Alumina (WFA) is an important raw material for advanced refractories and abrasives. WFA is widely used raw material in refractories, ceramics, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and many of other applications.
Available fractions
0-1mm, 1-3 mm, 3-6 mm, 5-8 mm, powder, or according customers requirements.
Packaging:
Bulk, big bags
Properties:
Tabular Alumina is a pure sintered alpha-alumina material that has been fully densified by rapid-sintering without the use of sintering aids at temperatures in excess of 1800 °C. Tabular Alumina has characteristc large and well developed hexagonal tablet shaped alpha-alumina crystals of up to 200 μm length.
0-0,05 mm, 0,5-1 mm, 1-3 mm, 3-6 mm, 5-8 mm, powder 180 mesh, 200 mesh or according customers requirements.
Applications:
Tabular Alumina is good choice as aggregates of unshaped and shaped high performance refractories. It is used in a variety of industries such as steel, foundry, cement, petrochemical, ceramic and waste incineration. Other common applications include its use in electrical insulators, kiln furnace and as a catalyst support. Ground Tabular is an excellent product to be used as a filler in epoxy or resin systems where high dielectric strength, thermal conductivity or abrasion resistance are desired.
Brown Fused Alumina is made of high-quality bauxite and refined in electric arc furnace at more than 2000 °C. Thanks to its high purity, good crystalization, strong fluidity, low linear expansion coeNicient and great corosson resistance, brown fused alumina is wide used as raw material of refractory product.
0-1 mm, 1-3 mm, 3-6 mm, 5-8 mm, powder according to customers requirements.
Mainly used for abrasion and high temperature resistant, inoxidizable aaggregate and filling of shaped and monolithic refractories in steel metalurgy, various industrial ovens, electric furnace etc...
Bauxite is one of the principal ore of aluminium. Bauxite contains hydrous aluminium oxides and aluminium hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas. Bauxite is obtained by calcining (heating superior grade bauxite at high temperature ranges fromm 850 °C to 1600 °C). In this way moisture could be removed to increase the alumina content.
0-1 mm, 1-3 mm, 3-6 mm, 5-8 mm, 16-30 mesh, 30-60 mesh, 120 mesh, 200 mesh, 325 mesh or as customers requirements.
Calcined Alumina is made from industrial aluminium hydroxide or industrial alumina, i tis generally used to produce slide gate sets, submerged entry nozzles, ladle shrouds, corundum bricks etc. It could also be used together with reactive alumina in monolithic refractories to increase liquidity, decrease water addition and porosity, increase strength and get lower linear change.Reactive a - Alumina micro powder is widely used ot produce refractory castable for steel ladle, castable for iron flow through, purge plug, well block, corundum self-flow refractory castable, gunning repairing mass, etc.
Dear Burned Magnesite is made from selected natural magnesite. It is produced by mine selecting, purifying and calcinating in shaft-kiln. High temperature performance and high density, easy to rapidly sintered, good thermal stability, strong alkali slag resistance, long service life, etc.
0-0,09 mm, 0-1 mm, 1-3 mm, 3-6 mm, or as customers requirements.
Fused Magnesite is manufactured by fusion raw magnesite ores which have advantaged of firm and tight structure, stable chemical properties, high strength etc. This high grade alkali fused magnesite is mainly used in matellurgy, chemical scientific and research.
0-30 mm, 0-120 mm or as customers requirements.
