SK34 Firebrick is a high quality Clay refractory brick. It typically has a yellowish color and a standard cuboid shape, often with dimensions like 230×114×65mm. Classified as fire clay brick, it contains at least 38% Al₂O₃ and no more than 2% Fe₂O₃. This chemical composition gives it excellent chemical stability and resistance to slag.
