Material Properties of Titanium Diboride
The physical, mechanical, and thermal properties of polycrystalline TiB2 are examined with an emphasis on the significant dependence of the properties on the density and grain size of the material specimens. Using trend analysis, property relations, and interpolation methods, a coherent set of trend values for the properties of polycrystalline TiB2 is determined for a mass fraction of TiB2 ⩾ 98...
متن کاملElastic-Stiffness Coefficients of Titanium Diboride
Using resonance ultrasound spectroscopy, we measured the monocrystal elastic-stiffness coefficients, the Voigt C ij, of TiB2. With hexagonal symmetry, TiB2 exhibits five independent C ij: C 11, C 33, C 44, C 12, C 13. Using Voigt-Reuss-Hill averaging, we converted these monocrystal values to quasiisotropic (polycrystal) elastic stiffnesses. Briefly, we comment on effects of voids. From the C ij...
متن کاملTitanium diboride ceramics for solar thermal absorbers
Titanium diboride (TiB2) is a low-density refractory material belonging to the family of ultra-high temperature ceramics (UHTCs). This paper reports on the production and microstructural and optical characterization of nearly fully dense TiB2, with particular interest to its potential utilization as novel thermal solar absorber. Monolithic bulk samples are produced starting from elemental react...
متن کاملDetermination of impurities in pharmaceutical preparations containing folic acid.
In the presented study, the HPLC method was used for the determination of impurities (p-aminobenzoic acid and p-aminobenzoyl-L-glutamic acid) in single-component pharmaceutical products containing folic acid. The determination was performed using a spectrophotometric detector at lambda = 269 nm wavelength.
متن کاملPulsed Laser Deposition of Epitaxial Titanium Diboride Thin Films
Epitaxial titanium diboride thin films have been deposited on sapphire substrates by Pulsed Laser Ablation technique. Structural properties of the films have been studied during the growth by Reflection High Energy Electron Diffraction (RHEED) and ex-situ by means of X-ray diffraction techniques; both kinds of measurements indicate a good crystallographic orientation of the TiB 2 film both in p...
