Which is the higher content of ligh

Hello, of course, the activity content of light burned magnesium oxide is higher. Taking Tianhua glass magnesium plate as an example, the active content of the light burned magnesia powder is more than 85%, which can combine with the magnesia chloride powder well to produce chemical reaction and 518 crystal with structural strength. However, it is difficult to participate in the activation reaction because of the lack of activity of MgO.
