industrial high temperature Si3N4 ceramic arm handle clamp
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
After the various oxide nano-film coated graphite is treated at 500 ° C, the oxide coated on the surface is in an amorphous manner, and the oxide coated on the graphite surface forms a COM (M represents metal) bond with graphite. , has the characteristics of chemical adsorption. After the graphite is coated with nano-oxide, the shape of the particles changes, the average particle size increases, and the surface fractal dimension increases. The wetting angle of the nano-oxide-coated graphite and water is greatly reduced with respect to the untreated graphite, and the graphite coated with the aluminum oxide exhibits a more hydrophilic type and a high dispersion stability. In addition, the surface activity of the oxidation reaction of the graphite coated with nano-aluminum oxide (VK-L30) is enhanced, and the oxidation resistance is enhanced. Graphite surface coated with titanium dioxide has no significant improvement in oxidation resistance. The oxidation resistance of graphite coated with nano-zirconium dioxide and chromium trioxide is reduced. This is the catalytic effect of zirconium dioxide and chromium oxide on carbon-oxygen reaction. The use of nanotechnology can produce better refractory materials. Nano-powder does have a significant improvement in the performance of refractory materials.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
