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 […]

Silicon carbide is an increasingly popular material due to its great mechanical, thermal and electrical properties. Recrystallized silicon carbide has unique properties due to its microstructure. RSiC is often utilized in kiln furniture and ceramic products such as refractories, wear-resistant industries and industrial high temperature kilns due to its excellent corrosion resistance and temperature resistance

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

Carbura de siliciu este un material din ce în ce mai popular în toate industriile datorită proprietăților sale mecanice și electrice impresionante, în special datorită ratei sale scăzute de dilatare termică și a caracteristicilor de rezistență. Datorită acestei proprietăți, este un candidat ideal pentru fabricarea oglinzilor pentru telescoape. Este prezentată o metodă de producere a carburii de siliciu recristalizat, care constă în reducerea carbotermică. Acest procedeu încălzește
