Tabular Alumina Description
Tabular Alumina is a high-purity sintered alumina material produced without any additives at ultra-high temperatures (up to 1900°C). It features a fully crystalline, alpha-alumina structure with low porosity and excellent thermal shock resistance. This makes it ideal for demanding industrial applications such as refractories, ceramics, and abrasive materials.
Tabular Alumina Key Features
- ≥ 99.5% Al₂O₃ Purity
- Excellent thermal shock resistance
- High mechanical strength
- Low water absorption
- Dense, uniform crystal structure
- No glass phase or additives
Tabular Alumina Specifications
| Property | Typical Value |

Frequently Asked Questions about Tabular Alumina
1. What is Tabular Alumina?
Tabular Alumina is a high-purity sintered form of alumina (Al₂O₃) with a completely crystalline, alpha-phase structure. It is produced at ~1900°C without any sintering aids, making it extremely stable under high temperatures.
2. What are the main applications of Tabular Alumina?
Tabular Alumina is widely used in refractories, ceramics, abrasives, kiln furniture, and foundry materials due to its excellent thermal shock resistance and mechanical strength.
3. How is Tabular Alumina different from Fused Alumina or Calcined Alumina?
Unlike fused alumina, which is melted and quickly cooled, tabular alumina is sintered slowly at very high temperatures. It has no glassy phase, lower porosity, and offers better thermal stability. Compared to calcined alumina, it is denser and more suitable for high-temperature structural applications.
4. What particle sizes are available from BanlanChem?
BanlanChem offers a wide range of particle sizes including 0–1 mm, 1–3 mm, 3–5 mm, and custom sizes based on your requirements.
5. Is Tabular Alumina available in bulk packaging?
Yes. We offer packaging options such as 25kg PE-lined bags, 1000kg jumbo bags, and customized packaging for large-volume or export needs.
