Profile: Hefei Kaier Nanotechnology & Development Ltd. Co. produces nano-powder materials. We produce nano powders of titanium nitride, silicon carbide, aluminum nitride, nickel and silicon. Nano titanium nitride powder possesses high purity, small and uniform particle diameter, high surface activity, large specific surface area, low loose loading density, anti high temperature, anti-oxidation, high strength high hardness & excellent thermal conductibility. It is used in knives, moulds and crucibles for smelting metals. Nano-SiC ceramic powders are used to make structure devices. These have high hardness, wear resistance and good self-greasing effect, thermal conductance, low thermal expansion efficient & high temperature strength. SIC also is one kind of semiconductors with good properties. It can be used to treat the metal surfaces and makes treated metal devices have high anticorrosion, high wear resistance, anti-high temperature & good absorption property.
