  • Silicon carbide powder and sintered materials - J-Stage

    Silicon carbide (SiC) was first industrially synthesized in 1894 and has been used as refractories, abrasives and high temperature furnace parts. The basic fabrication and sintering technologies were almost established by about 1970. Recently, sintered SiC has become a key material as it has been widely used in

    Feb 14, 2014 With the advent of powder nanotechnologies [6], a unique opportunity of sintering of high-density silicon carbide ceramics within the traditional ceramic After forming and pressing, samples were sintered in the laboratory induction furnace type HFI-25 under argon atmosphere during 1 h with an average

  • Silicon Carbide - InTechOpen

    Apr 4, 2011 sintering (LPS) or mechanical alloying (MA) will be detailed. structural and electrical properties of the fabricated SiC will be discussed as a function of the synthesis methods. 2. SiC structures. More than 200 SiC surface energies of Si and C faces which influenced the formation of different polytypes.

  • Processing and properties of macroporous silicon carbide ceramics

    Partial sintering is the simplest, frequently used and most conventional method to fabricate porous SiC ceramics. Particles of powder compact are bonded by partial sintering due to surface diffusion, evaporation–condensation, recrystallization or a solution–reprecipitation process. We can see a homogeneous pore structure

  • Laser sintering of ceramics - ScienceDirect

    The laser sintering technique uses a high-energy laser beam to fuse powder granules directly into complex 3D net shape components in a layer-by-layer manner. Repeatedly a . SiC is a highly refractory compound that dissociates before melting, so laser sintering through a melt-solidification mechanism is not feasible.

  • A study on commercial SiC-powders sintered by hot - BIBSYS Brage

    Hot-pressing of a commercial silicon carbide powder was performed with 0, 5 and 10wt% of exaggerated grain growth upon reaching the sintering temperature, with subsequent recrystallization. A boron-carbon exchange mechanism between SiC and BN is The furnace design is still the most common silicon carbide.

    submicron size β-SiC, sintering of silicon carbide to near theoretical density was achieved. He proposed that during the firing of pure submicron powders of covalently bonded solids, densification is prevented by a hypotheti- cally high ratio of grain-boundary to solid–vapour surface energies, i.e. γGB/γSV. In order that a pore
