Composite Ceramic Materials Used Nano Magnesia Powder
Spec: 20-30nm, 99.9% purity.
Application for nano magnesia powder:
1. Preparation of ceramic capacitor
dielectric material obtained ceramic grain size can be controlled within the
range of 1000nm, dielectric loss, material uniformity, suitable for the
production of large-capacity, high insulation resistance, ultra-thin dielectric
layer (dielectric layer thickness of less than 10μm) multilayer ceramic
capacitors. Its addition amount of 0.5-5%
2. Nano-ceramic powder, is made of nano magnesium
oxide, nano silica, nano alumina, nano-zinc oxide and other preparation, in
which nano-magnesium oxide 0.5-4.0%, and the obtained nano-ceramic powder has
far infrared radiation, antibacterial, activated water, purified water, the
dissolution of trace elements beneficial to human health, release negative
ions, improve seed germination rate and other health functions. It can be
widely used in a variety of ceramic products, environmental protection,
textiles, drinking water treatment, equipment and containers such as alcohol
and tobacco industries.
3. With the nano-alumina, titanium dioxide
and other obtained nanocomposite sintered ceramic additives can be prepared
precious metals Ni heat-resisting steel alternatives. Wherein the amount of
magnesium oxide nano 5 to 18%.
4. The nanocrystalline composite ceramics,
nano-titanium dioxide, nano-magnesium oxide, nano-rare earth oxides and
zirconium dioxide as an additive part, successfully Amorphous ZrO2 content up
to 10 ~ 30wt%, to obtain a high zirconium Al2O3 -SiO2-ZrO2 ceramics,
nanocrystalline composite ceramics, crystal phase content of greater than 90%,
the main phase of mullite, and cristobalite tetragonal zirconia, tetragonal
zirconia grains dispersed where size is less than ≤1μm . Use of materials prepared by the invention, which is superior to
conventional methods for preparing the same composition of material properties,
the hardness increased by 30%, the toughness increased by 6%, the intensity
increased by 40%.
