Through optimized firing and controlled particle size distribution, tabular alumina delivers outstanding physical properties and superior long-term stability in harsh industrial environments.
Key Advantages
Excellent refractoriness and thermal stability
Low open porosity and high bulk density
Outstanding slag and metal corrosion resistance
High thermal shock resistance
High mechanical strength at elevated temperatures
Chemically inert and phase-stable α-Al₂O₃
Low impurity content (Fe₂O₃, SiO₂)
Typical Applications
Tabular Alumina is widely used in:
High-performance refractory bricks and shaped refractories
Monolithic refractories (castables, gunning, ramming mixes)
Steel ladle and tundish linings
Sliding gate plates and nozzles
Aluminum extrusion dies and glass furnace refractories
Kiln furniture and burner blocks
Ceramic grinding media and wear-resistant parts
Its superior properties significantly extend service life and reduce furnace downtime.
