Product Description:
Refractory industry application tabular alumina TA are high-purity sintered alpha-alumina spheres (in various sizes),which is fired at extremely high temperatures(>1900) to reduce porosity to a very low level.The high temperature process leads the growth of large plate-like, alpha-alumina crystals giving"tabular"alumina its name.
Refractory industry application tabular alumina TA is of high refractoriess,excellent thermol shock resistance,fantastic anti-creeping and anti-strippingperformance.
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.
Benefits of Tabular Alumina Balls
Tabular alumina balls are long lasting, smooth, high chemical purity, resistant to thermal shock, and resistant to the mechanical and abrasive actions found in catalyst support systems. Additionally, tabular alumina balls do not produce fines and dust to contaminate the product stream, and are unaffected by oxidizing and reducing atmospheres at temperatures well below the softening point.
Application:
Refractory industry application tabular alumina TA grains are used in the refractory industry for making monolithics as well as shaped product.
* Slide Gate refractory for CC Section.
* LCC,ULCC Castables along with many dense castable
* Precast Pre Fired Product for Glass & Boiler Industry,Such as Porous plug,Well Block,Impact Pad.
* Different Section of BF for lining as shape & monolithic
* Shape refractories such as AMC bricks for ladle,VD,VOD Metal Zone and Bottom Impact Part.
* Refractory filler & Kiln furniture.
