  • Publication number: 20220127198
    Abstract: Methods of flash sintering have been developed in which particle are initially coated with thin layers by atomic layer deposition (ALD). Examples are provided in which 8 mol % yttria-stabilized zirconia (8YSZ) particles are coated with small quantities of Al2O3 by particle atomic layer deposition (ALD). Sintered materials that result from the process have been characterized. Sintered materials having unique characteristics are also described.

  • Patent number: 10541064
    Abstract: A method of manufacturing a silicon carbide (SiC) sintered body and a SiC sintered body obtained by the method are provided. The method includes: preparing a composite powder by subjecting a SiC raw material and a sintering aid raw material to mechanical alloying; and sintering the composite powder, wherein the sintering aid is at least one selected from the group consisting of an Al—C-based material, an Al—B—C-based material, and a B—C-based material. Accordingly, a SiC sintered body that can be sintered at low temperature, can be densified, and has high strength and high electrical conductivity can be prepared.
