Light-burned magnesia powder, short for light-burned magnesia powder, is a kind of active magnesia obtained by calcining magnesite, brucite and magnesium hydroxide extracted from seawater or brine at about 800-1000 C. Light burnt magnesia powder is a light yellow and light brown powder. Its particle size is mostly below 100 mesh. Its crystal density is 3.07-3.22g/cm3. Its lattice constant is large, its lattice defect is large, its texture is brittle, its porous structure is very active, it is easy to react with water to form Mg(OH)2, which hardens and has bonding energy. Power.
Choosing calcining way and controlling light burning temperature is an 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 degrees, the recrystallization speed of MgO increases, the dispersion decreases sharply and the activity becomes worse. Different calcination methods and equipment at the same temperature are also important factors affecting MgO activity. If calcined in fluidized bed furnace and suspension furnace, it can decompose rapidly in an instant, and the lightly burned magnesia powder with the greatest activity can be obtained. Using tunnel kiln and reflective kiln as large blocks, the calcination time is long, and the surface is often overburned while the interior is burned, which will reduce the activity of light-burned magnesia powder. When calcining granular magnesite in rotary kiln, the situation is between the two, and the activity of light-burned magnesia powder can also be maintained.
Light burnt magnesia powder is a kind of raw material with medium basicity and chemical activity. It is used in other industrial fields besides refractory and cementitious materials. In addition, the development of converter slag splashing technology has further expanded the application scope of light burned magnesia powder. At present, the slag splashing technology mostly uses light-burned magnesia powder as pellets, such as light-burned magnesia powder pellets, carbon-containing light-burned magnesia pellets and carbon-containing calcium-containing light-burned magnesia pellets.
