The melting point of the main crystal phase periclase is 2800 ℃. It starts to sublimate at 1600 ℃ in vacuum and above 2000 ℃ in reducing atmosphere. The density is greater than 3.40g/cm, the porosity is 0%~10%, the Mohs hardness is 5.5, and the resistance to alkaline slag corrosion is very strong. The periclase is often cube, octahedron or irregular granular, and the cube is completely cleaved
