General description

Cytotoxicity of magnesium oxide nanoparticles on human neural cells and fibroblast was studied. It was found that of all the other metal oxide nanoparticles, MgO nanoparticles were least capable in inducing cell death.

Application

Nanoparticles of magnesium oxide may be used in forming Al2(1-x)MgxTi(1+x)O5 ceramic powder. A composite dielectric material may be prepared by loading poly(methylsilsesquioxane) (PMSQ) on MgO nanoparticles. MgO nanoparticles were used to nucleate ice under a certain temperature and pressure conditions.

Features and Benefits

  • Ultra-fine nanoparticles reduce sintering time in ceramic synthesis, enhancing efficiency.
  • Consistent surface area across batches ensures reliable performance in nanocomposites, cosmetics, and coatings.
