How to Detect Activity of Magnesium Oxide?

by Allen Hu magnesium oxide supplier

   The activity of magnesium oxide is very important to produce some raw material. Not enough activity will lead to bad quality of material. Therefore, it is necessary to detect magnesium oxide activity. For a layman, how to detect activity of magnesium oxide? Now, as a professional magnesium oxide manufacturer, Meishen Technology teaches you some steps:
1. In the stock magnesium oxide, taking each 100 grams of magnesium oxide sample from different positions(no less than 3 places), and admixing it equably.
2. From the equably powder, taking 100 grams of magnesium oxide powder to put into constant and dry beaker. And then, making it wet completely after adding 400 grams of clearwater.
3. Putting the beaker into drying baker. This drying baker has already been set 110℃. After 2 hours or more, set the temperature to 150℃ until drying the sample to constant.
Activity Computing Method: the activity of MgO =【(W—100)/45】X100%

   In this equation, 100 is the sample weight before hydration. W is the sample weight after hydration. 45 is conversion ratio.
Note: in order to get more accurate numerical value, you can take triplet 100 grams of magnesium oxide powder. And counting up the last numerical value from three times, and dividing three.

   Point that needs attention:

   ① During the heating process, you should avoid slurry sloping beaker.

   ② Drying time should be long as far as possible. It can guarantee the water evaporate thoroughly.
