Tabular Alumina
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.
