The lattice parameter
of garnet-1 was close to that of almandine (Fe garnet, a = 11.526 [Angstrom]).
The FCC lattice parameter
for the [Cr.sub.23][C.sub.6] carbides was calculated from the XRD diffraction charts yielding to 1.075 nm, which is consistent with the values of 1.06 to 1.11 nm reported in the literature [14-16].
Table 1 summarizes the position and the width at midheight (FWHM) of the main peaks, along with the lattice parameter
values calculated from the XRD patterns of the pure and codoped ZnO nanopowders.
Two factors, namely strains and lattice parameter
changes, will contribute to the shift of diffraction peaks .
The effects of ball milling on the hydrogen sorption and disproportionation behaviors of [Zr.sub.0.8][Ti.sub.0.2]Co sample can be deduced from the changed microstructure including lattice parameter
, morphology, elemental composition, and crystal defects.
where a is the lattice parameter
, u is unbroadened by faulting, b is the number of reflections broadened, and [L.sub.0] is the third coordinate replacing (hkl) indices ([L.sub.0] = h + k + l) .
The term [lambda](|x - x'| , [alpha]) is a kernel function representing nonlocal modulus, where |x - x'| is a distance in Euclidean space and [alpha] is a material parameter depending on internal and external characteristics (lattice parameter
, granular size, distance between C-C bonds, graphene sheet length, wave length, etc.).
The peak profile analysis and lattice parameter
determination has been carried out JCPDS-data.
11 Ghadim reported Se4+ has an association with enamel lattice parameters
along the a-axis and c-axis.5 The ionic radius of Se4+ (0.50 A) is larger than that of P5+ (Phosphate) (0.35 A), For that reason, on substitution in synthetic HAp the lattice parameter
From 1998 to 2011, the NIST lattice comparator played an important role in the International Avogadro Project by measuring lattice parameter
variations in highly perfect isotopically natural silicon material and highly enriched [sup.28]Si material [2-4].
