How many degree numbers does it need?
As anyone who has studied chemistry at school knows, the magnesium carbonate can directly generate magnesium oxide under high temperature. However, many people don’t know that how many degree numbers does magnesium carbonate generate magnesium oxide? Next, Meishen Technology explains in detail for everybody. The magnesium carbonate can produce magnesium oxide and carbon dioxide by decomposing at high temperature. The decomposition temperature of magnesium carbonate is 540℃. When the temperature achieves 790℃, magnesium carbonate can be break up into magnesium oxide and carbon dioxide. The higher temperature, the higher content of magnesium oxide. In the magnesium carbonate, 47.6% is the theoretical value of magnesium oxide content. It is quite right. In the natural magnesite, the content of top grade product is between 46% to 47%. However, generally speaking, the magnesium carbonate produced by industrialization was the alkaline mode magnesium carbonate. The national standard stipulate: the content of magnesium oxide should be between in 40% to 44%. As this point, the specialist from Meishen Technology teaches you a method again. That is: how to judge the magnesium oxide was generated from? Is it from magnesium carbonate or magnesium hydrate? What method can know it? The magnesium oxide generated from magnesium carbonate has more pores, that is: it has smaller density. So we just determine its bulk density: take the same volume magnesium oxide, and weight them. We can know it easily. If in the lab, you should use the mixing cylinder with stopper with 100ml. The powder should be added into it breakdown in three steps. In order to promise the volume not change every step should jolt ramming. And then, you can compare them. Meishen Technology is a new high-tech enterprise specialized in the research, manufacture and sale of magnesium oxide. Since the company was established in 2003, it helped customers to solve various of problems through reliable products, systematic service and professional engineering experience. At the present time, the magnesium oxide product and service from Meishen Technology have been closer to voice of customers. What’s more, this company has been the specialist and a leading position in magnesium oxide industry. Now Meishen has already established the sales and technical service network in more than 30 provinces. It made every customer can apply the products and service of Meishen Technology and be easier.
