Large SSA ceramic grade MGO Magnesium Oxide nanopowders   R652: Magnesium Oxide NanoPowder(MgO), 20-30nm, 99.9%, white solid powder.   Application of MGO Magnesium Oxide nanopowders in ceramic field 1. Preparation of ceramic capacitor dielectric material. The grain size of the obtained ceramic can be controlled within the range of 1000nm, with small dielectric loss, good material uniformity, which is suitable for the production of  multilayer ceramic capacitor with large-capacity, high insulation resistance, ultra-thin dielectric layer (dielectric layer is less than 10um). The addition amount is about 0.5%-5%. 2. Nano-ceramic powder, made of nano magnesium oxide, nano silica, nano alumina, nano zinc oxide and other powders, among which, nano magnesium oxide is 0.5%-4.0%, and the obtained nano ceramic powder having a far-infrared radiation, antibacterial, activated water, purified water, the dissolution of trace elements which are beneficial to human health, release of negative ions, improve seed germination rate and other healthy functions. It can be widely used in various ceramic products, environmental protection, textiles, drinking water treatment, equipment and containers such as alcohol and tobacco industries. 3. Sintered with nano Alumina( nano Al2O3), titanium dioxide(TiO2) and other together, obtaining nanocomposite ceramic additives can take place of precious metals Nickel/Ni to produce heat-resisting steel alternative. Wherein the amount of nano-magnesium oxide is 5%-18%. 4. Nanocrystalline composite ceramics makes use of nano titanium dioxide(TiO2), MGO Magnesium Oxide nanopowders, nano rare earth oxides and zirconium dioxide(ZrO2) as part of the additives, and successfully increased the content of Amorphous ZrO2 to 10-30wt%, and obtained a high zirconium Al2O3 -SiO2-ZrO2 ceramics, nanocrystalline composite ceramics, and crystal phase content is more than 90%, the main phase is mullite, cristobalite and tetragonal zirconia, tetragonal zirconia grains dispersed in which size is ≤1μm. Through this method, the properties of the materials are superior to that of conventional methods for preparing the same material. The hardness increased by 30%, the toughness increased by 6%, and the strength increased by 40%. 5. The glass ceramic coating,composed of MGO Magnesium Oxide nanopowders, nano silica(SiO2), boron oxide, nano alumina(Al2O3), cerium oxide nanoparticles, can effectively improve the mechanical strength of the catalyst, including abrasion resistance, hardness, compressive strength and impact resistance; and enhance active centers of the catalyst, thereby increasing the activity of the catalyst, saving the active ingredient and reducing costs. It is mainly used in diesel and gasoline engine for exhaust gas purification treatment processors. Wherein the amount of nano magnesium oxide(MgO) is 5%-18%. 6. Preparation of high toughness ceramic materials, using nano magnesium oxide(MgO) and yttrium oxide(Y2O3) or rare earth oxide as nano composite stabilizer to produce partially stabilized zirconia ceramics with excellent mechanical properties and resistence of high-temperature aging. The ceramic material can be widely used in high-temperature engineering components and advanced refractories. 7. As auxiliary components of the anti-reducing dielectric ceramic material. The addition amount is 0.001%-10mol% 8. As single-side carbon dioxide gas shielding arc welding ceramic plate material. Its addition amount of nano MgO is 1-10 wt% 9. The glass ceramics, nano silica(SiO2), nano titanium dioxide(TiO2), nano alumina(Al2O3), nano magnesium oxide(MgO) sintered glass ceramics can be processed by the float glass method to be transparent, especially for thin film semiconductor substrate, specifically applicable to the display and solar cell. Wherein the amount of nano magnesium oxide(MgO) is 6%-20%. by Corrine
