Lightweight fireclay bricks for boiler

Al₂O₃ (%) ≥42; Fe₂O₃ (%) ≤3.0
Bulk Density (g/cm³)≤1.2
Reheating Linear Change, 1150℃ 2h (%)≤0.6

Application:

Lightweight fireclay bricks as power plant boiler refractories mainly used for heat insulation wall building, because of light weight, low thermal conductivity and high refractoriness.
