On the stoichiometry of zirconium carbide [PDF]
Scientific Reports, 2020 AbstractThe dependencies of the enhanced thermomechanical properties of zirconium carbide (ZrCx) with sample purity and stoichiometry are still not understood due to discrepancies in the literature. Multiple researchers have recently reported a linear relation between the carbon to zirconium atomic ratio (C/Zr) and the lattice parameter, in contrast ...

Silicon Carbide Platelet/Silicon Carbide Composites [PDF]
Journal of the American Ceramic Society, 1995 α‐silicon carbide platelet/β‐silicon carbide composites have been produced in which the individual platelets were coated with an aluminum oxide layer. Hot‐pressed composites showed a fracture toughness as high as 7.2 MPa·m1/2. The experiments indicated that the significant increase in fracture toughness is mainly the result of crack deflection and ...

Effect of Silicon Carbide and Tungsten Carbide on Concrete Composite
Materials, 2022 Flexural strength of concrete is an important property, especially for pavements. Concrete with higher flexural strength has fewer cracking and durability issues. Researchers use different materials, including fibers, polymers, and admixtures, to increase the flexural strength of concrete.

Capturing the oxidation of silicon carbide in rocky exoplanetary interiors [PDF]
, 2018 Theoretical models predict the condensation of silicon carbide around host stars with C/O ratios higher than 0.65 (cf. C/O$_{\mathrm{Sun}}$ = 0.54), in addition to its observations in meteorites, interstellar medium and protoplanetary disks. Consequently,

Supported Molybdenum Carbide and Nitride Catalysts for Carbon Dioxide Hydrogenation
Frontiers in Chemistry, 2020 Catalysts based on molybdenum carbide or nitride nanoparticles (2–5 nm) supported on titania were prepared by wet impregnation followed by a thermal treatment under alkane (methane or ethane)/hydrogen or nitrogen/hydrogen mixture, respectively.
