Oxide Magnesium Oxide Magnesite MGO Caustic Calcined Magnesite CCM Refractory Material

Basic Info.

Product Description

Light-burned magnesia is to calcinate magnesite, brucite and magnesium hydroxide extracted from seawater or brine at about 800~1000ºC, decompose and discharge CO2 or H2O. Light burned magnesium is widely used in building materials, chemical industry, metallurgy, medicine and other fields. It is an ideal material for the production of fireproof boards, lightweight partition boards, magnesium sulfate, papermaking, desulfurization technology and slag splashing in steel mills. Light burned magnesia is calcined magnesite, brucite and magnesium hydroxide extracted from seawater or brine at about 800~1000°C, decomposed and discharged CO2 or H2O, that is, light burned magnesia powder, also known as light burned magnesia and caustic magnesium Burning or light magnesium burning, commonly known as bitter soil powder. Lightly burned magnesia powder is loose in texture and high in chemical activity, and can be used to make magnesium cement, magnesite building materials, heat insulation materials, etc. It is also an intermediate product for the production of high-quality magnesium oxide by two-step calcination. When light-burned magnesia is heated, equiaxed periclase appears at about 600 °C. When the temperature reaches 650°C, equiaxed periclase disappears and non-equiaxed periclase is produced. At 80°C, equiaxed periclase completely disappears. These periclase lattices have high surface energy due to point defects and dislocations. The crystal lattice of MgO has less water than the lattice group of MgCO3, so the pores between the lattices increase, the porosity is high, the specific surface area is large, and the activity is high. Lightly burned magnesium powder is light yellow and light brown powder, mostly below 100 mesh, and the periclase crystals are very small The light burning temperature and light burning time of light burnt magnesite have a certain influence on the activity of light burnt magnesite powder. Magnesite is calcined at 600°C, 650°C, 700°C, 750°C, 800°C, 850°C and 900°C, respectively, and the calcination temperatures of 700°C, 750°C and 800°C are within 15 to 90 minutes. Activity was not significantly affected. The effects of 600°C, 650°C, 850°C and 900°C on the activity are particularly significant, and the activity increases significantly with time when calcined at 600°C and 650°C. When calcined at 80°C and 900°C, the activity decreased significantly with the prolongation of hydrocarbon calcination time.
