A revised structure model of ettringite is presented, in order to provide quantitative X-ray diffraction (QXRD) this mineral cement pastes. The derived from two different existing models, both which are suitable for restricted use but inferior the refined presented. In first published proposed by Moore and Taylor [Acta Crystallogr. B 26, 386–393 (1970)], none 128 positions H given unit cell, results reduced scattering power quantification purposes. For precise samples together with anhydrous...
A suitable external standard method which was first described by O’Connor and Raven (1988) (“Application of the Rietveld refinement procedure in assaying powdered mixtures,” Powder Diffr. 3, 2–6) used to determine quantitative phase composition a commonly Ordinary Portland Cement (OPC). The also applied order amorphous contents OPC. Also investigated were impact atomic displacement parameters microstrain on calculated content. investigations yielded evidence that said do indeed exert an...
The structural information on the influence of ionic additions in biphasic (hydroxyapatite (HAP) and β‐tricalciumphosphate (β‐TCP)) mixtures ranging from single substitutions to combined most essential ions embedded biological apatite was analyzed through Rietveld refinement technique. results have proved that determined quantitative phase composition HAP β‐TCP dependent initial calcium (Ca) deficiency precursor powders precipitated different molar concentrations used synthesis. substitution...
Lithium silicate-based glass ceramics have evolved as a paramount restorative material in and prosthetic dentistry, exhibiting outstanding esthetic mechanical performance. Along with subtractive machining techniques, this class has conquered the market satisfied patients' needs for long-lasting, excellent, metal-free alternative single tooth replacements even smaller bridgework. Despite popularity, not much is known about chemistry, microstructure terminal behaviour. This article combines...
This article reports the derivation of a physically based geometric description mean diameter orthogonal shapes and provides an efficient formalism to relate these reciprocal lattices corresponding apparent crystallite sizes. The following descriptions provide reasonable approximation for simulation refinement anisotropic domain morphology in powder diffraction techniques.
