High alumina arc brick, also known as high alumina arch brick, is a type of refractory brick that is designed for use in high-temperature applications such as industrial furnaces, kilns, and other thermal equipment. These bricks are made from high-grade raw materials, consisting of high alumina content, and are manufactured using a specialized process to ensure high heat resistance and durability.

High alumina arc bricks are known for their excellent thermal properties, including high refractoriness, good thermal shock resistance, and high strength at elevated temperatures. This makes them suitable for applications where they are exposed to extreme heat, such as in steelmaking, cement plants, glass manufacturing, and other high-temperature processes.
These bricks have a high alumina content, typically ranging from 48% to 95% alumina (Al₂O₃), which gives them superior resistance to thermal and chemical attack. The high alumina content enables them to withstand the corrosive effects of molten metals, slags, and gases encountered in many industrial processes.
High alumina arc bricks are available in different grades, with varying alumina content and other additives to enhance specific properties. The selection of the appropriate grade depends on the operating conditions, such as temperature, atmosphere, and the nature of the materials being processed.
