Magnesium oxide nanoparticles (Magnesium oxide, Nanometer), molecular formula MgO, relative molecular mass 40.30, like other nanomaterials, first of all, shows the commonality of nanomaterials, especially the surface effect is more obvious, that is, with the reduction of particle size, the surface area of magnesium oxide increases significantly, the surface energy rises, reflecting the high reactivity, strong adsorption, good low temperature sintering, etc. Features.
Hebei Messi Biology Co., Ltd. research shows that with the decrease of the particle size of magnesium oxide nanoparticles, the ratio of surface atoms to the total number of atoms in the bulk phase increases, and the negative pressure on the grain elements caused by the interface makes the grains appear lattice expansion, resulting in the resistivity of nanocrystalline magnesium oxide is significantly higher than the corresponding amorphous materials.
Application areas.
①Nano magnesium oxide can be used in electrical insulation materials, cosmetics, spices, paints, rubber fillers, especially it can play a better effect than ordinary magnesium oxide, obviously improve the performance of products.
②Nano magnesium oxide can be used as...
