Tabular Alumina Powder <200 Mesh | Al₂O₃ 99.2%
Tabular Alumina powder <200 mesh, Al₂O₃ 99.2%, acts as bond-phase filler in low-cement castables for steel ladle linings, blast furnace troughs, and petrochemical reformer furnace floors.
// Key Features
- Fine <200 mesh gradation filling inter-granular voids to minimize castable porosity
- High chemical purity Al₂O₃ 99.2% preventing flux contamination in the bond phase
- Low SiO2 ≤0.05% ensuring phase stability without secondary mullite formation
- Excellent reactivity with calcium aluminate cement for superior green and fired strength
