The facility found to shape the field, popularized these products make them extremely important, being obtained by molding, drying and cooking of mixtures containing clay. ¹
The clay can be defined as a natural material, earthy texture, fine-grained, consisting predominantly of clay minerals and may contain other minerals that are not clay, organic matter and other impurities. ²
The development of ceramic products in recent decades is evident, even to be used in different areas of science, as in medicine in bone and dental prosthesis, the coating chips in livestock, in this case allowing a more accurate count and secure; in manufacturing knives with blades of porcelain and the need for materials with high temperature resistance, in addition to many other applications, such as the aerospace industry. ³
Among the various ceramic products, those produced using red clay are of extreme importance for the development of housing cities.
Comparing the test results with the previous downturn, it is concluded that, despite the greater number of bodies with plastic clay present high linear shrinkage, the other characteristics are superior to other groups.

The potential of RS can be determined by using the value of Straw-to-Grain Ratio (SGR) of 1.5 [4] and [5].
Thus, each RP will generate approximately 150% RS, so as to obtain the equation: RS = SGR × RP (1) Furthermore, the energy potential of RS (EPRS) can be obtained by using the equation: EPRS= WRS × CVRS (2) where WRS = number of RS, and CVRS = calorific value of RS.

Introduction
During the past few decades, oil companies have established and applied quite a number of oil recovery methods to mature and mostly depleted oil reservoirs.
In this study, 60ft coiled sandpack was filled with 150-180 microns of rounded grains glass beads to represents sandstone reservoir rock.

The lower values on average microhardness of the HAZ in relation to BM was due to high temperature developed during the welding process that caused a coarsening and recrystallization of the grains [13].
At tensile test it was observed that the fracture occurred in the same welded joint in which the greatest number of bubbles and lower hardness.

As can be seen, the HMO film consists of only (200) (400) peaks, and no diffraction from randomly oriented grains or impurity phases can be observed from the x-ray pattern, indicating that the films are fully epitaxial growth with a-orientation on NSTO (110) substrates.
Fig. 5 shows the Cole-Cole figure of the HMO film under different temperature, it is clear that the Cole-Cole figure is minor arc shape, showing the relaxation time is not a single number.

Researchers investigated a number of methods to prepare SnSe thin films viz. atomic layer deposition [7].
The average size of particles has been obtained from the x-ray diffraction pattern using the Scherrer’s formula D = k λ/ β cos (11) where D is the grain size, K is a constant taken to be 0.94, β is the full width at half maximum (FWHM) and λ is the wave length of the x-rays (1.5406Ǻ).
