1, preparation of ceramic capacitor dielectric material, the grain size of the resulting ceramic can be controlled in the range of 1000nm, small dielectric loss, good material uniformity, suitable for the production of large capacity, with high insulation resistivity, ultra-thin dielectric layer (dielectric layer thickness less than 10μm) of multilayer ceramic capacitors. Its magnesium oxide addition amount is 0.5-5%.
2, nano ceramic powder, is prepared by nano magnesium oxide, nano silicon oxide, nano alumina, nano zinc oxide, etc., of which nano magnesium oxide 0.5-4%, the resulting nano ceramic powder has radiation far infrared, antibacterial, activation of water, water purification, dissolution of trace elements beneficial to human health, release of negative ions, improve the germination rate of plant seeds and a variety of health functions. It can be widely used in various ceramic products, environmental protection, textile, drinking water treatment, tobacco and wine equipment and containers and other industries.
3, and nano alumina, nano titanium dioxide, etc. together with the sintered nano-composite ceramic additives can replace the precious metal nickel to prepare heat-resistant steel. Among them, the nano-magnesium oxide additive amount 5 ~ 18%.
4, nanocrystalline composite ceramics, using nano titanium dioxide, nano magnesium oxide, nano rare earth oxides and some zirconium dioxide as additives, successfully increased the amorphous ZrO2 content to 10-30wt%, to obtain high zirconium Al2O3-SiO2-ZrO2 system microcrystalline, nanocrystalline composite ceramics, its crystalline phase content is greater than 90%, the main crystalline phase is mullite, tetragonal zirconia and square quartz. The tetragonal zirconia grains are diffusely distributed therein, and the size is less than ≤1 μm. the performance of the material prepared using...
