2 . Product Description
Tabular alumina is produced by sintering ball-formed, intermediately burned calcined alumina at a temperature just under the 2040º C melting point of aluminum oxide.
Refractory white tabular aluminais a pure sintered α-alumina materials that has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess 1900°c.
Refractory white tabular alumina has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to 200μm length.
These tabular alumina balls are then crushed, graded or screened, ground and blended to a wide range of granular or powdered particle size distributions.
3 . Product Performance
1. Low open porosity and large crystals with closed spherical pores
2. High refractoriness, high mechanical strength and abrasion resistance
3. Good chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion.
Application:
Refractory industry application tabular alumina TA grains are used in the refractory industry for making monolithics as well as shaped product.
* It goes into various applications such as
* LCC,ULCC Castables along with many dense castable
* Precast Pre Fired Product for Glass & Boiler Industry,Such as Porous plug,Well Block,Impact Pad.
* Shape refractories such as AMC bricks for ladle,VD,VOD Metal Zone and Bottom Impact Part.
* Slide Gate refractory for CC Section.
* Varieties of Ramming and Mortar mixes.
* Insulation Bricks and castables.
* Bottom Pouring Bricks.
* Refractory filler & Kiln furniture.
* Different Section of BF for lining as shape & monolithic
Apart from the above,the product is widely used in various applications ranging from Steel, Foundry, Incineration, Cement, Glass, Metal and Petro Chemical industry.
