Light calcined magnesium powder, referred to as light calcined magnesium powder, is an active magnesium oxide obtained by calcining magnesite, brucite and magnesium hydroxide extracted from seawater or brine at about 800~1000 ℃. Light burnt magnesium powder is light yellow and light brown powder, with particle size of less than 100 mesh, periclase crystal is very small, density of 3.07~3.22g/cm3, lattice constant is large, lattice defects are many, texture is brittle, porous structure, reaction activity is large, easy to conduct solid reaction or sintering, and react with water to produce Mg (OH) 2 and harden, with bonding ability.
Selection of calcination method and control of light calcination temperature are important means to obtain good activity. With the increase of calcination temperature, the specific surface area of MgO decreased significantly. When the temperature is greater than 1000 ℃, the recrystallization rate of MgO increases, the dispersion decreases sharply and the activity becomes worse. Using different calcination methods and calcination equipment at the same temperature is also an important factor affecting the activity of MgO. If fluidized bed furnace and suspension furnace are used for calcination, it can be rapidly decomposed in an instant to obtain the lightly-burned magnesia powder with maximum activity. The use of large blocks in tunnel kiln and reverberatory kiln will lead to long calcination time, often resulting in surface over-burning and internal combustion, which will reduce the activity of light-burned magnesia powder. Using rotary kiln to calcine granular magnesite, the situation is between the two, which can also make the light burned magnesia powder keep good activity.
Light calcined magnesium powder is a kind of raw material with medium alkalinity and chemical activity. It is also used in other industrial fields besides being used as refractory and cementing material. In addition, the development of converter slag splashing protection technology has further expanded the application scope of light burned magnesia powder. At present, the slag splashing furnace protection technology is mostly used after the light-burned magnesia powder is balled, including the light-burned magnesia powder ball, the carbon-bearing light-burned magnesia sub-ball and the carbon-bearing calcium-containing light-burned magnesia ball.
