1, The content of magnesium oxide and activity in a range is proportional to, in fact, there is no such a severe or reliable proportional relationship; Light burning magnesium powder

2,Assume that "outside this range is inversely proportional" is a serious mistake!

3. Today's magnesium oxide is misinterpreted by some people as light burning powder, which is also a serious mistake. It should be said that the main ingredient of light burning powder is magnesium oxide, and light burning powder also includes MgCO3, Mg(OH)2, CaO, Fe2O3, Al2O3, SiO2 and other impurities. Conversely, it is seriously wrong to refer to magnesium oxide as light baking powder.

4, as time and technology renovation, light burning powder and ling magnesia also attack serious change, the definition of ling magnesia magnesite are old kiln firing, color gray, particularly high content of impurities, light burning powder was also mostly by magnesite fire, different using reflection kiln firing at this stage is the light burning powder, much less impurity content.

Qualified light sintering powder should conform to the standards of WB/T 1019-2002 Light Burned Magnesium Oxide for Magnesite Products and HG/T 2573-2006- Industrial Light Magnesium Oxide. It is not possible to meet these standards. Also have a deep misunderstanding, using ethylene glycol extraction method for determination of f - in light burning powder, CaO its content according to the experiment, ethylene glycol is also absorbed the magnesium oxide, with different extraction time, the results will be visible, it touches some country standard correction, this statement also coincide with some other articles. This proposal is important, and experts can further argue it.
