Which is the higher content of light

Of course, the activity content of light burned magnesia is higher. Taking Tianhua sand glass magnesium plate as an example, the active content of its light burned oxidized self magnesia powder is more than 85%, which can well combine with magnesium chloride powder 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 MgO activity in the re fired MgO powder.
