Fabrication of size-controlled SiC/Si3N4 ceramic microspheres with enhanced extinction property

Porous SiC and SiC/Cf Ceramic Microspheres Derived from Polyhydromethylsiloxane by Carbothermal Reduction

“…Spherical particles confined in dimensions within the micrometer range exhibit superior properties to their bulk counterparts. They provide good flowability, high packing density and easy access to particle surfaces [ 7 , 8 , 9 , 10 ]. In addition, hierarchical porosity gives the materials a high surface area and facile infiltration of liquids to their pores [ 7 ].…”

“…In addition, hierarchical porosity gives the materials a high surface area and facile infiltration of liquids to their pores [ 7 ]. Porous SiC-based microspheres could be used in many fields, such as: catalysis [ 11 , 12 ], hot gas filtration [ 13 ], thermal insulation [ 10 ], sensors [ 14 ], absorbers [ 15 , 16 ], molten metal filtering [ 17 ], membranes [ 18 , 19 ], and tissue engineering [ 20 ]. The interest has recently been focused on SiC composites as potential semiconductor materials for absorption of electromagnetic waves [ 21 ], anodes of lithium-ion batteries [ 22 ] and supercapacitors [ 23 ].…”

Synthesis of cross‐linked polymer microspheres and pyrolysis conversion to polymer‐derived ceramics

“… have prepared various Si–C–N–(Ni) magnetic ceramics microspheres with dimensions from micro‐ to nanoscale with an assistance of polymer template of linear polystyrene via a novel phase separation assisted pyrolysis strategy. Kang et al . have fabricated SiC/Si 3 N 4 ceramic microspheres via the combination of emulsion technology and the PDC process.…”

“…Zhang et al 29 have prepared various Si-C-N-(Ni) magnetic ceramics microspheres with dimensions from micro-to nanoscale with an assistance of polymer template of linear polystyrene via a novel phase separation assisted pyrolysis strategy. Kang et al 30 have fabricated SiC/Si 3 N 4 ceramic microspheres via the combination of emulsion technology and the PDC process. Liu et al 31 prepared the novel core-shell ceramic microspheres composed of a SiCN inner core and TiO 2 nanoparticles outer shell via emulsion reaction and PDC process.…”

Synthesis of the in-Situ Si3N4-SiC Composite Nano Powders by Carbothermal Reduction

“…On the other hand, nanocomposites can be divided into three categories; intragranular, intergranular composites and nano/nano composites. In these types of ceramics the aim is to improve not only the mechanical properties such as hardness, fracture strength and toughness and reliability at room temperature, but also high-temperature mechanical properties, such as hardness, strength, and creep and fatigue fracture resistances [14][15][16][17][18][19][20]. * corresponding author; e-mail: fcaliskan@sakarya.edu.tr…”
