SILLIMANITE BRICKS
Castable super

Sillimanite bricks comes with series of extensive variety of products with several AL2O3 content & low-iron Sillimanite Bricks with the highest CO resistance and phosphate additive to enhance hostile nature to slagging. Our sillimanite bricks are pre-high burned and are therefore particularly volume-stable in high temperature applications. Despite the high burning, varieties with marvellous low open porosity and exceptional thermal shock resistance are aligned in the range.
