Fireclay bricks are a type of refractory brick made from clay and other materials that are highly resistant to high temperatures and thermal shock. The main components of fireclay bricks include:
1.Clay: Fireclay is a type of clay that is naturally found in earth's crust and is rich in alumina and silica. It forms the backbone of fireclay bricks and provides them with their high refractory properties.
2.Kaolin: Kaolin is another type of clay that is added to fireclay bricks to increase their plasticity and workability during the manufacturing process.
3.Silica: Silica is an important component of fireclay bricks because it increases their resistance to thermal shock and chemical corrosion.
4.Alumina: Alumina is also added to fireclay bricks to increase their strength and resistance to high temperatures.
5.Other materials: Depending on the specific application, fireclay bricks may also contain other materials such as magnesia, calcium oxide, and zirconia to provide additional properties such as improved thermal conductivity or chemical resistance.
The exact composition of fireclay bricks can vary depending on the manufacturer and the intended application. Different combinations of raw materials and manufacturing processes can produce fireclay bricks with a range of properties suited for specific high-temperature applications such as furnaces, boilers, kilns, and incinerators.
