The crystal creates a platform for developing a pattern for mean positions of the atoms in the crystal. One can also manage to determine the chemical bonds of the structure, say carbon in diamond crystals and the varying disorders of some of the crystalline structures. Carbon is common in crystal formation.
X-ray crystallography has been applied in many scientific fields due to the presence of crystals of many chemical compounds and elements. A pure crystalline structure is that of table salt, scientifically known as sodium chloride and represented by the chemical formula NaCl. Crystalline structures that have been studied by X-ray crystallography are many. Some of them are calcium fluoride (CaF2), calcite (CaCO3) and pyrite (FeS2). Others are spinel (MgAl2O4) and brucite (MgO4) among others. The inclusion of X-rays in studying crystalline structures enabled further understanding of these compounds in a manner that had never been used before and allowed for formation of more complex compounds through chemical reactions caused by interaction of crystalline structures.
X-ray crystallography can be used to identify and locate unusual electronic properties of a material by studying their electron positions and mobility. It is also a tool for noting elastic properties of a material considering the chemical interactions that occur within the crystal and the associated processes. With these properties, X-ray crystallography is used in the design and manufacture of pharmaceuticals. Their application involves combining elements and modifying their crystalline structures to ensure that they bond as required (Clegg, 1988).
Other than X-ray crystallography, there are other methods associated with determining atomic structures (Rhodes, 2006). However, they all rely on the principle of diffraction. These ...Download file to see next pagesRead More

The second part X-ray Diffraction (XRD) Powder X-ray
...Task: The second part X-ray Diffraction (XRD) Powder X-ray Powder X-ray diffraction is among the primary methods, which are used by solid-state chemists and mineralogists to examine physic-chemical build-up of solids, which are unknown to them. The data is denoted in a group of single-phase X-ray powder diffraction forms of three strong D values in table form (Khan 24). The tables include mineral name, relative intensity (I/I) and interplanar spacing. The method takes a sample material and places a sample of powder in a holder. Illumination of the sample then follows with...

X-Ray Powder Diffraction
...?X-Ray Powder Diffraction 503509) Introduction X-Ray powder diffraction is used widely in geological studies for the purpose of identifying the composition of minerals present in different rock formations. This provides a quicker method of identifying crystalline structures when compared to optical light microscopy or scanning electron microscopy. (Marta J.K Flour, 1997) Theory A non amorphous material consists of a three dimensional structure having atoms in a series of planes separated by a distance. When X-Rays are directed on to this structure, part of it is transmitted the specimen, some part is absorbed, a part is refracted and the...

X-ray Fluorescence
...X-Ray Fluorescence Introduction X-rays were discovered by Wilhelm K. Rontgen (1845 – 1923), a German physicist (Shackley 7). These rays have a long history in commercial elemental analysis since the discovery of the correlation between a sample’s atomic weight and the X-rays radiating from it, a fact that enabled Henry G. J. Moseley number elements in 1913 through the observation of K-line transitions as observed in X-ray spectrum. This formed the basis of element identification through X-ray fluorescence spectroscopy by considering the relationship...

...X-rays are electromagnetic waves lying between UV radiation and -rays. They were discovered by German physicist, Wilhelm Rntgen, and have wavelength 0.01-10.0 nm and frequency 30-30,000 1015 Hz). Main physical properties of X-rays could be described by the experiments where beam of x-ray photons interact with matter. Monochromatic beam of X-ray photons is directed perpendicularly to the electric and magnetic fields. For simplicity they often consider the electric field only and neglect the magnetic field. From a quantum mechanical perspective a monochromatic beam is viewed as being...

What's in an X-ray Room
...X-Ray Room al Affiliation What is in an X-Ray Room? From among the components that are generally found in an X-ray room, the following three components are reportedly deemed essential: (1) X-ray tubes; (2) an X-ray table; and (3) lead shields and gowns; to name a few. X-ray tubes could actually have different configurations where it could be mounted on the ceiling, on the wall, on the floor or as mobile or c-arm tubes, depending on the need and resources of the health care or diagnostic institution. It is important since this equipment is used to take different radiographic procedures to determine causes of illnesses or source of the patients’ health dilemmas. An X-ray table is equally important to position the patient according... to the...

X-ray Exposure Components
...X-Ray Exposure Components of X-Ray Exposure Components The X-ray equipment uses electromagnetic radiations to develop an object’s image, commonly with the intention of envisioning something situated beneath the surface of that object. The radiation emitting from the x-ray machine relies mainly upon kVp (tube voltage), mA (the x-ray tube current), s (exposure time) and cm (the distance between focus and detector). The dosage is defined by these parameters. So the major technical factors that affect an X-ray exposure are time, kVp, mA and...
