Hebei Messi Biology Co., Ltd. stated that nanomagnesium oxide has a molecular formula of MgO and a relative molecular mass of 40.30. Like other nanomaterials, they first show the common characteristics of nanomaterials, especially the surface effect. That is, as the particle size decreases, the surface area of magnesium oxide significantly increases, and the surface energy increases, reflecting a very high Reactivity, strong adsorption, good low-temperature sintering and other characteristics.
As the particle size of nanocrystalline magnesium oxide decreases, the ratio of surface atoms to the total number of atoms in the bulk phase increases. The negative pressure on the grain components caused by the interface causes the grains to expand lattice, resulting in a significant resistivity of nanocrystalline magnesium oxide. higher than corresponding amorphous materials.
Application areas:
① Nano-magnesium oxide can be used in electrical insulation materials, cosmetics, spices, paints, and rubber fillers. In particular, it can have better effects than ordinary magnesium oxide and significantly improve the performance of products.
② Nano-magnesium oxide can be used as a carrier for supported catalysts for the synthesis of methanol and lower alcohols, which can improve the performance of the catalyst;
③Can be used as a pharmaceutical polish;
④Can be used as a high-efficiency dissociation adsorbent to adsorb toxic chemicals, such as chlorine-containing hydrocarbons, organophosphorus compounds and acidic gases, for environmental protection;
⑤ It can be used as a dopant to be incorporated into Bi2Sr2CaCu2O8 powder. This powder is deposited on the silver surface to form a high-temperature superconducting thick film.
⑥ Nano-magnesium oxide can also be used as a sintering aid and stabilizer for nanoparticles such as magnesium oxide, aluminum oxide, and iron oxide to obtain high-quality nanophase ceramics.
