Comparison of the experimental X-ray diffraction pattern with the JCPDS card showed that the Cd[In.sub.2][O.sub.4] and Cd[In.sub.2][O.sub.4]:[Er.sup.3+] crystals have a cubic crystal
We also obtain the structure of the coefficient matrix in the case of thermoelastic waves propagation in anisotropic media, orthorhombic, tetragonal, hexagonal, and cubic crystal
Only materials in the cubic crystal
system have only one refractive index.
In this study, polycrystalline copper metallicis an important material with face centre cubic crystal
In the work [6, 7] with the use of analytical and numerical models of the polycrystal P, Q, F parameter values were got for a large number of metals with cubic crystal
The lattice constant value a = 4.114 [Angstrom] is determined from the XRD data and is well matched with the reported value (a = 4.115 [Angstrom]) [18-20] for Mg[B.sub.6] (JCPDS data card number 08-0421) existing in body centered cubic crystal
structure (the space group Pm3m) .
Figure 3 shows the intermediate state of spherical crystal morphology transforming into cubic crystal
morphology, and the comparison with Figure 2(a) explains that the effect of ammonia in the calcium carbonate crystal growing process is to accelerate the precipitate into spherical morphology.
For cubic crystal
lattices, there are only three independent coefficients: [c.sub.11], [c.sub.12], and [c.sub.44].
Steel alloys that operate in high-temperature situations, such as aircraft engines and metal-forming machinery, are often austenitic, meaning they have as their primary base a face-centered cubic crystal
. These crystals have multiple contacts--or lattice points--per flat surface, giving them extra strength even when operating temperatures skyrocket.
Chang and coworkers (3) also found that the cubic crystal
size of the neat POSS (in the absence of polymer) was quite large (> 20 [micro]m).
At temperatures and pressures found at Earth's surface, pure iron has a structure called a body-centered cubic crystal
. In such an arrangement, eight atoms form the corners of a cube with a ninth atom in the center.
