CORESIC® SG

CORESIC® SG Pressureless sintered silicon carbide (SSiC) by Gel Casting
 

 

Material Characteristics

The use of ultra-fine silicon carbide micropowder (particle size is usually 0.5-1.0μm) as raw material, B4C-C sintering additives, without granulation, directly to the silicon carbide powder, added to the monomer, crosslinking agent, water, dispersant, defoamer, toughening agent, PH adjusting agent, retardant and other additives to form a pre-mixed solution, in the catalyst and the initiator of the action of the monomer cross-linking agent curing to form a three-dimensional network structure, ceramic Powder locked in the gel network, after gel chemical reaction in situ curing to form a green body, vacuum or argon gas protection under high temperature sintering (temperature is usually in 2100-2200 ℃), the density is generally 3.05-3.1g/cm3, the grain size is generally not more than 20μm.
 

 

Features and Applications

CORESIC® SG silicon carbide material has a very high with excellent mechanical properties, thermal conductivity, excellent high-temperature stability, as well as good specific stiffness and optical processing properties, with good low-temperature and high-temperature corrosion resistance, suitable for the manufacture of chemical corrosion-resistant products, heat exchange, and high-temperature load-bearing components, used in chemical heat transfer, lithium-ion new energy, high-temperature kilns, semiconductors and other fields.
