The high-performance chrome-corundum brick is made mainly from high-purity corundum and fused chromium oxide by high-pressure forming and high-temperature firing. It has high strength, excellent thermal shock resistance and strong resistance to acidic substances such as V₂O₅ and SO₂, and performs very well at the top of the regenerators of large float-glass furnaces fired with petroleum coke.
