Silicon carbide is an extremely hard and strong material with high density, exceptional corrosion resistance and outstanding tribological properties. Available both sintered and reaction bonded forms. Pressureless sintering provides high densification through reduction of surface energy of grains due to boron and carbon reaction1, but its high temperature leads to excessive grain growth that compromises […]

Siliciumcarbid er et stadig mere populært materiale på grund af dets gode mekaniske, termiske og elektriske egenskaber. Rekrystalliseret siliciumcarbid har unikke egenskaber på grund af sin mikrostruktur. RSiC bruges ofte i ovnmøbler og keramiske produkter som ildfaste materialer, slidstærke industrier og industrielle højtemperaturovne på grund af dets fremragende korrosionsbestandighed og temperaturbestandighed.

Recrystallized silicon carbide (RSiC) offers exceptional high-temperature strength and abrasion resistance, making it the go-to material in a range of applications. Thanks to its unique microstructure, recrystallized SiC outshone both reaction sintered or pressureless sintered SiC in terms of thermal, mechanical and chemical properties. RSiC is produced through slip casting, extrusion or injection molding processes

Sintered silicon carbide (SiC) is an inert ceramic material with numerous applications, from temperature tolerance and chemical/mechanical resistance, to excellent chemical and mechanical properties. Reaction bonded SiC ceramics are produced using porous carbon feedstock in inert atmospheres through various forming techniques such as dry pressing, casting or extrusion – creating products of all shapes. Hardness

Reaction bonded silicon carbide (RB SiC) is formed by infiltrating a porous carbon or graphite preform with molten silicon. Although it boasts lower hardness than sintered silicon carbide, its excellent wear resistance make up for any potential differences. Metal matrix composite (MMC) material is also ideal for manufacturing larger wear components in mining and other

Reaction bonded silicon carbide (RBSC) is an extremely strong and resilient ceramic that finds use in numerous applications such as gas turbine engines and wear components. Reaction bonding involves infiltrating porous carbon material with molten silicon to produce an elastic ceramic hybrid that can be shaped using conventional ceramic forming techniques such as pressing, injection

Siliciumcarbid er et stadig mere populært materiale på tværs af industrier på grund af dets imponerende mekaniske og elektriske egenskaber, især dets lave varmeudvidelseshastighed og styrkeegenskaber. På grund af disse egenskaber er det en ideel kandidat til fremstilling af teleskopspejle. Der præsenteres en metode til fremstilling af omkrystalliseret siliciumcarbid, som består af karbotermisk reduktion. Denne proces opvarmer
