Microstructural characterization of boron-rich boron carbide

Acta Materialia, 2017
Abstract Boron carbide has a wide range of solubility, but the effects of stoichiometry on its microstructure and mechanical response are not well understood. In this study, detailed microstructural characterization was carried out on three hot-pressed B-rich boron carbide samples.

Thermal expansion of boron and boron carbide

Journal of the Less Common Metals, 1986
Abstract Thermal expansion of poly crystalline α-rhombohedral boron (in the range from 300 to 1270 K), of β-rhombohedral boron (from 300 to 1470 K) and boron carbide B 4 C (from 300 to 1970 K) have been investigated by means of high temperature X-ray diffractometry. The linear coefficients of thermal expansion perpendicular ( α ⊥ ) and parallel ( α

Thermoelectric properties of phase pure boron carbide prepared by a solution-based method

Advances in Applied Ceramics: Structural, Functional and Bioceramics, 2019
In this work, we report the thermoelectric properties of phase-pure carbon-rich boron carbide B4.05C synthesised from a sucrose precursor (here noted as ‘High Purity’ boron carbide) by a solution-based method.

Predicting two-dimensional semiconducting boron carbides

Nanoscale, 2019
Carbon and boron can mix to form numerous two-dimensional (2D) compounds with strong covalent bonds, yet very few possess a bandgap for functional applications.

Sintering of boron carbide and boron carbide-silicon carbide two-phase materials and their properties

Journal of Nuclear Materials, 1988
Boron carbide is a high-technological ceramic material (it is used for lightweight armor, neutron absorbers, wear pieces, etc.). Hot pressing (2200°C, 40 MPa, Ar atmosphere) and recently high isostatic pressing, are the best known ways for industrial preparation of boron carbide items.

Auger-electron spectra from boron carbide

Physical Review B, 1985
Auger electron spectroscopy (AES) has been used to study the surface composition and electronic structure of hot-pressed samples of boron carbide. The samples had bulk compositions of B/sub 9/C and B/sub 4/C. After removing oxygen and excess carbon contaminants from the surfaces of the samples by noble-ion sputtering the AES estimates of surface B/C ...
