Product Introduction
High chrome brick (also known as high chrome refractory brick) is a special refractory material mainly composed of chromium oxide (Cr₂O₃) and aluminum oxide (Al₂O₃). Due to its excellent high temperature performance and corrosion resistance, it is widely used in specific high temperature and corrosive environments.
