Classification and Features of Different Types of Refractories
· The classification can be based on the position of the metal in the periodic table whose oxide is under consideration as refractory material. The Refractories can be classified depending whether it is in shaped form or as powder (unshaped). The shaped refractories can be further classified based on its process of giving shapes.
