Burned (t = 900°C) thin-grained diatomite, the composition of which is presented in Table 1, was used in the work.
On the basis of the previously performed X-ray diffraction studies of the products of hydration of aluminate phases of cement with organic additives, it is possible to assume that, at small dosages of additives, the retarding effect of the SP at the initial stage of formation of hydrosilicate phases (due to adsorption processes on hydrates) is not so great while the stabilizing effect of SP on hydrates AFm-phases lead to the formation of the lamellar structure of metastable calcium hydroaluminates with a large number of atomic contacts and as a trace to some acceleration of the growth of plastic strength.

The dynamic process of crystallisation and recrystallisation during the oxidation modifies the oxygen diffusion coefficient by decreasing the grain size distribution and finally the number of short circuit paths in the oxide layer along the grain boundaries.

The bed was composed of powder mixture of Al (99.5% purity, grain size 200 μm)-silicon (97.5% purity, grain size about 40 μm) as metallic donor.
Equivalent circuit of protective scale model Taking into account the dispersion effect, a constant phase angle element CPE = [Q(jω) n] -1 was used to describe the element Cdl and Cox in the fitting procedure, where j is the imaginary number, Q is the frequency independent real constant, ω= 2πf is the angular frequency (rad/s), f is the frequency of the applied signal and n is the CPE exponent[8].

For instance, ferroelectric thin films as well as bulk ceramics have had a strong impact in a large number of technological applications such as in ferroelectric memories and piezoelectric devices.
Particle shape is also an important factor as symmetrical particles pack more efficiently and consequently spherical grains are preferred.
This is indicative of the formation of large sintered grains, much larger than that of the feed-stock material.

The samples were polycrystalline with a large grain size (several mm2); an ion beam of around 1 mm2 was used in the measurements in order to get diffusion profiles in only one of such grains.
The number of plane waves used, given by the parameter RKM = 7, corresponds to an energy cutoff of 15 Ry.

Furthermore, large numbers of the sample are more needed for further analysis to present valid equations with having a high correlation.

The fracture behaviour of ceramics has been improved by using the reinforcing action of grain anisotropy or second phase and the promotion of crack shielding effects by the phase-transformation or micro-cracking [1-2].
Conclusion This study shows that that a certain number of requirements (thickness, composition and stacking sequence) correlated to the laminate architecture are responsible for the mechanical behaviour of the material.

The fractal dimension can be measured in a number of ways.
They concluded that the increase in toughness from 4.5 to 8.3 MPa•m 1/2 with increasing grain size and aspect ratio was caused by crack deflection and crack bridging from platelike grains.

(1999) carried out a large number of triaxial compression tests on granular soil encased in single and multiple geocells to study the influence of geocell confinement on the strength and stiffness behaviour of granular soils.
The sand has a relatively uniform grain-size distribution with median grain size (D50) of 0.54 mm and coefficients of uniformity ( uC ) and curvature ( cC ) of 2.30 and 1.01, respectively.

Within the scatter and the limited number of results there is clear linear relationship between drop height and DFE, similar to that seen in quasistatic edge flaking.
An initial evaluation of the behaviour obtained with a sharp indenter was made on a fine-grained 99% alumina.
It has been shown, unsurprisingly, that a sharp impactor produces flaking more readily than a blunt impactor, probably Figure 12: Comparison of edge impact behaviours of a fine-grained 99% alumina with a 2 mm ball and with a Vickers indenter. because of the dominance of radial cracking.
