When purchase active magnesium oxide, there are something need to be mentioned. The activity we usually called is refers to the degree of reaction, while activity is determined by the thickness of magnesium oxide solid particles. Compared with ordinary magnesium oxide, the requirements for active magnesium oxide is different. For example, the appropriate particle size distribution, the average particle size:< 2 μm (2000nm); microscopic morphology is irregular particles or nearly spherical particles or crystal plate; the activity represent by citric acid (CAA) is 12~25s (the higher of the value, the lower active); the activity represent by absorbing iodine value is (80~120mgI2/100gMgO); specific surface area 5~20m3/g; apparent specific volume 6~8.5mL/g.
However in simple words, light magnesium oxide is belong to basic salts, the content of MgO plays an important role for activity. In general,high pure magnesium oxide are made by basic magnesium carbonate in long time of low temperature, special type furnace structure, energy consumption is higher, the finished product has large apparent specific volume, this is what to be noticed.
