Introduction SiC Ceramic Bushing Elbow
Reaction sintered silicon carbide sic ceramic bushing elbow is one of the most widely used refractory ceramic product.Adopting slip casting process,mature sintering technology and extraordinary finishing ability,very suitable for manufacturing oversize products with complex shapes and tight tolerances.As a new material, vacuum reaction sintering silicon carbide sic ceramic bushing can be made into various wear-resistant parts and corrosion-resistant parts,has been successfully used in metallurgy,chemical industry,raw material processing,transportation of high corrosion and wear fluid substances,mechanical seals,powder processing, automotive, paper making, aviation, aerospace, medicine, food processing, surface sanding treatment and optical reflectors etc.For example, SiC ceramics can be used for all types of bearings, balls, nozzles, seals, cutting tools, gas turbine blades, turbocharger rotors, reflecting screens, and rocket combustion chamber linings etc.
Characteristics SiC Ceramic Bushing Elbow
Sic ceramic bushing features:
- High hardness, reaction-bonded silicon carbide is one of the hardest high-performance materials next to diamond.
- High strength and excellent crossbow and fracture resistance performance.
- Light weight,the specific gravity of sic ceramic bushing is less than half of metal alloys,it is 40% of steel, roughly the same as aluminum.
- Denseness,the theoretical density of reaction bonded silicon carbide shaped parts is 98% of 3.21 g/cm2, and the minimum density is 3.0 g/cm3.
- Corrosion, oxidation and erosion resistance,the high density, low porosity and chemical inertness of SiC sintered silicon carbide shaped parts make it possible to operate in hot gas and liquid environments, oxidizing and corrosive atmospheres, as well as in strong acids and bases under high temperature.
- Wear resistance,the ultra-high hardness and density of the sic ceramic bushing make it ideal for some special parts,such like some parts that easily subject to high wear and sliding wear.
