The property and usage of Magnesia Brick
Refractoriness of magnesia brick high reaches above 2000 ℃, and refractoriness under load with the combination of phase's melting point and at high temperatures result in different liquid
phase without great changes. General magnesia brick's load softening temperature is at 1520 ~ 1600 ℃, and high purity magnesium boast a softening start temperature can reach 1800 ℃.
The difference between start refractoriness under load of magnesia brick and collapse of temperature is not big, it is because the main phase composition is periclase magnesia brick, but
periclase crystals within the magnesia brick is not crystalline network skeleton, but was cemented by combination. High purity magnesia brick's refractoriness under load start temperature can
reach 1800 ℃, mainly due to the combination between the periclase grain is forsterite or dicalcium silicate, it and MgO formed eutectic mixture's melting temperature is high, crystal lattice strength
is big and plastic deformation under high temperature is small, crystal particles combined are good.
