Tabular alumina is produced by sintering ballformed, intermediately burned calcined alumina at a temperature just under the 2040º C melting point of aluminum oxide. These tabular alumina balls are then crushed, graded or screened, ground and blended to a wide range of granular or powdered particle size distributions.
1. During the calcining, the microcrystalline phase patent technology is used to make the grain smaller of alpha alumina, and fill effect better in castable refractory. crystal morphology of alpha alumina has been effectively controlled, grain surface is approximate ball type or ball type. 3.
Alpha phase alumina is the strongest and stiffest of the oxide ceramics. Its high hardness, excellent dielectric properties, refractoriness and good thermal properties make it the material of choice for a wide range of applications. High purity alumina is usable in both .

ZIRCAR Ceramics'' Tabular Alumina Type TAB99 Balls and Gravel are highdensity, highpurity Alumina in the AlphaAlumina crystal phase. Hightemperature sintering imparts a strong, lowporosity microstructure which gives TAB99 excellent hightemperature strength, high refractoriness and superior dielectric properties.
Reactive alumina: These grades are predominantly alpha alumina having wider particle size distribution. They yield a low water demand with very good flow properties when used in low–cement castables, ULCC and selfflow castable mixes.
We are the world''s leading producer of alumina. With installed refinery capacity of 17 million metric tons per year, we currently operate six refineries in Australia, Brazil and Spain, and have a 25 percent share in the refinery that is part of our Ma''aden joint venture in Saudi Arabia.
ASB90 inert alumina balls are 90+% alpha alumina which provide high physical strength, maximum resistance to thermal shock, erosion, high density and thermal conductivity make it an ideal choice for the synthesis gas industries specifically, which can prevent silica leaching in the presence of high water partial pressures.
Fused cast Alumina Block TYM Description Fused cast Alumina Block TYM is formed by the compact structure of alpha alumina and beta alumina crystals in a most ideal proportion which is approximately 50% and 50% respectively,where intertwined crystals of both materials result in a very dense has dense structure and no contamination to glass.
American Elements produces Alumina Balls in various sizes for use in pumps, valves, flowmeters, and other applications. Alumina balls are lighter and more corrosionresistant than steel balls and can withstand high temperatures up to 1750°C. Alumina balls are generally immediately available in most volumes, including bulk quantities.

T162 Tabular Alumina Balls are highpurity sintered alphaalumina spheres (in various sizes). This product has been fired at extremely high temperatures (>1900°C) to reduce porosity to a very low level. This hightemperature process leads the growth of large platelike (or tabletlike) alphaalumina crystals giving "tabular" alumina its name.
