Experimental study on preparation of nanometer magnesium oxide by liquid-phase method

The system of this article introduces the nature of nano -magnesium oxide, and the current status of research at home and abroad has conducted an in -depth analysis of the process of preparing the process of nano -magnesium oxide.On this basis, combined with the results of small test experiments, the central tornado flow was designed for nano -magnesium magnesium -to -magnesium research experimental solutions.

Through experimental analysis of various influencing factors, the best process conditions for nano -magnesium oxide are optimized.Finally, through the modification of nano -magnesium oxide, the high decentralized and stable magnesium oxide modified powder after combining the compound key was obtained.the result shows:

1. When using sodium carbonate, magnesium chloride as the raw material, use a liquid phase method. When the central tornado stirrer amplifies magnesium oxide, the central tornado stirrer can meet the system heat transfer requirements. The temperature concentration is evenly distributed, so that the front body of the generated magnesium carbonate is completely and uniformly suspended in the reactor.

2. In the process of liquid reaction, adding sulfonol as a dispersant can well inhibit the growth of magnesium carbonate, and effectively disperse magnesium carbonate precipitation generated.

3. The central tornado stirrer prepares magnesium oxide. The best process conditions are: the reaction temperature is 30 ° C, the reaction time is 30min, the stirring speed is 350R/min; the concentration of magnesium chloride solution is 2mol/L, and the concentration of sodium carbonate solution is 2.5 mol/L; Disted sulfurnol adds 9.6ml; 煅 Boil conditions are: 90min at 500 ° C. Under this condition, a magnesium oxide powder with a uniform distribution of granularity is 14nm.

4. Magnetic oxide oxide can cause magnesium oxide surfaces to combine chemical bonds with AOT, so as to obtain nano -magnesium magnesium oxide particles with good decentralization, more stable, and more uniform granularity. The best conditions for modification are: modified temperature 40 ° C, and the modification time is 45 minutes.

  1. I know this if off topic but I’m looking into starting my own blog and was curious what all is needed to get set up? I’m assuming having a blog like yours would cost a pretty penny? I’m not very web smart so I’m not 100 positive. Any recommendations or advice would be greatly appreciated. Kudos

    1. It doesn’t cost too much, if you want to starting your own blog, I suggest Github blog, but it requires lots of web knowledge.
