Features

Features

Early Strength at Moderate Temperatures

Unlike sintered bricks, Laurel's phosphate high alumina bricks cure through chemical bonding, enabling rapid installation and high early mechanical strength—ideal for plants with minimal preheating time.

Exceptional Mechanical and Chemical Resistance

With Al₂O₃ content ≥70%, each phosphate bonded high alumina refractory brick offers superior protection against molten slag, corrosive gases, and mechanical abrasion in high-stress operating zones.

Dimensional Accuracy and Shape Flexibility

Laurel manufactures each custom phosphate bonded high alumina brick to precise dimensional tolerances, and offers customization for non-standard furnace designs or specific lining configurations.

Optimized for Mid-Temperature, High-Wear Conditions

These phosphate bonded high alumina refractory bricks are ideal for environments up to 1450°C where slag resistance, acid stability, and structural integrity are critical.
