High-alumina brick hi refractory material chi khat a ni a, a bul berah chuan aluminium oxide (Al2O3) atanga siam a ni.
Bricks with an Al₂O₃ content exceeding 90% are classified as corundum bricks. Standards vary by country due to differences in available resources; for instance, European standards set the minimum Al₂O₃ content for high-alumina refractories at 42%. In China, high-alumina bricks are typically categorized into three grades based on Al₂O₃ content: Grade I (>75%), Pawl II (60–75%), leh Pawl III (48–60%) te an ni.
