For background on alumina materials, see the overview by AZoM – The A to Z of Materials.
What Is Tabular Alumina?
Tabular alumina is a sintered α-alumina material produced by firing calcined alumina at temperatures above 1800°C without additives. The result is large, well-developed hexagonal crystals with extremely low porosity and excellent thermal shock resistance.
Its high purity (Al₂O₃ ≥ 99.5%) and stability make it ideal for high-performance refractory applications such as steel ladles, kiln furniture, and ceramic rollers. For more details on the material classification, refer to the Wikipedia Alumina entry.

Applications of Tabular Alumina
As a high-purity sintered alumina, tabular alumina plays a crucial role in various industries:
- Refractory bricks, castables, and monolithic linings
- Ceramic rollers and kiln furniture
- Polishing and grinding abrasives
- Electrical insulators and high-temperature components
- Foundry and metallurgical applications
Its unique crystal structure provides excellent high-temperature mechanical strength and corrosion resistance, outperforming conventional calcined alumina. For refractory applications, see Refractories World Forum for industry insights.
Tabular Alumina vs Fused Alumina
Although both are forms of alumina, their production methods and properties differ significantly:
- Tabular alumina is sintered at 1800°C, creating large α-alumina crystals with low porosity and high refractoriness.
- Fused alumina is produced by melting alumina in an electric arc furnace, resulting in denser but more brittle crystals.
