The wear resistance of refractories depends on the composition and structure of the materials. When the material is a dense polycrystal composed of a single crystal, the wear resistance mainly depends on the hardness of the mineral crystal of the constituent material. High hardness and high wear resistance of the material. When the mineral crystals are non-isotropic, the crystal grains are fine and the wear resistance of the material is high. When the material is composed of multiple phases, its wear resistance is also directly related to the bulk density or porosity of the material, and also to the bonding strength of each component. Therefore, in the case of a certain refractory material at normal temperature, the wear resistance is proportional to its compressive strength, and the sintered product is also excellent in wear resistance. The wear resistance of refractory products is related to temperature.
