This, first prepares the carbonate precursor of nano magnesia using nucleation/crystallization isolation method, can be obtained and receives using simple roasting
Rice magnesia.
But nano magnesia presoma is because easily occurring secondary nucleation and reuniting existing when being prepared in an aqueous medium
As being greatly reduced so as to cause the magnesia finished product absorption of subsequent roasting and degerming performance so that crystal is unordered uncontrollable, therefore late
Fail to be promoted in practice late, becomes the technical bottleneck that the material of this great potential is hovered always except practical application
One of.According to classical surface chemistry theory analysis, the reason of nanometer Mg salt precursor body is reunited may be very much that surface is negatively charged greatly
Active Mg in the nanometer Mg salt precursor body particle easily adsorbent solution of lotus2+Nucleating growth is carried out on its surface.If wanting to reduce
The appearance of reunion seeks to reduce or eliminate nanometer Mg salt precursor body particle to active Mg after all2+Absorption.Usually side
Method is that dispersing agent, surfactant such as polyethylene glycol, ammonium polymethacrylate, poly- hydroxy acid ammonium etc. are added in the reaction system to receiving
Rice grain is wrapped up, and then removes them by the method for subsequent heat treatment.But additive is organic matter mostly, and it is water-soluble
The intermiscibility of liquid is poor, and the nanoparticle growth that can only leave after being added, process are difficult to control, these disadvantages result in this method
Limitation.
