Sintering of Boron and Boron Carbide

Journal of Solid State Chemistry, 2000
An investigation of sintering kinetics of boron and boron carbide is presented. The influence of the powder size distribution on the temperature dependence of sintering, on reaching a high final density, and on gaining a homogeneous grain size has been shown.

Design and Syntheses of Poly(Norbornenyldecaborane) Precursors to Boron Carbide and Boron-Carbide/Silicon-Carbide Ceramics

MRS Proceedings, 2004
ABSTRACTPoly(norbornenyldecaborane) (PND) was synthesized via ruthenium catalyzed ring opening metathesis polymerization and was found to be a good single-source polymeric boron carbide precursor. Polymer blends of PND and allylhydridopolycarbosilane (AHPCS) were also found to be excellent precursors to boron-carbide/silicon-carbide composite materials.

Advanced microstructure of boron carbide

Journal of Physics: Condensed Matter, 2012
The rhombohedral elementary cell of the complex boron carbide structure is composed of B(12) or B(11)C icosahedra and CBC, CBB or B□B (□, vacancy) linear arrangements, whose shares vary depending on the actual chemical compound. The evaluation of the IR phonon spectra of isotopically pure boron carbide yields the quantitative concentrations of these ...
