General properties & features:
It has high purity, small particle diameters, large specific surface area, high surface activity, low loose loading density, excellent mechanic, thermal, electrical and chemical properties, e.g., it has high hardness and melting point, high wear resistance and fine self- lubricating, anti-creep, anti-oxidization, different radiation or adsorption of light, low thermal expansive coefficient and large high temperature strength. It can be used as microwave susceptor, semiconductor, IR radiation materials and so on.
Some Applications:
1) nanostructured materials: it provides hard, higher ductility and strength etc. mechanical properties, and self-lubricating, anti-corrosion/oxidization to be used in the sectors of metallurgical, petrochemical, mechanical, air/space-crafts, e.g. bearings or other anti-wear part, liquid fuel injector, crucibles, high power and frequency modules, semiconductor components.
2) SiC nano coatings on the surface of tools, moulds or functional components with some performances such as anti high temperature, thermal emission, wear resistance and absorption wave and lucency.
3) The nano composites with enhanced performances in the matrixes of metals, ceramics, and polymers. For example, composites of SiC and PI or silicon rubber can anti high temperature; used in the fuser film sleeve of laser printer made of polyurethane resin, SiC nanopowder can improve its thermal conductivity and wear resistance, prolong its life by two times; composites of SiC and alloy steel have the performance of high hardness and toughness.
4) New nucleating/refining or sintering agents in metals or alloys or polymer or ceramic or
microcrystalline glass materials for smaller grain size with improved mechanical properties etc..
5) It also can be used in the lubricants.
