Download or read book X Ray Diffraction Method for the Quantitative Characterization of Calcium Phosphate Coatings written by A. Burgess and published by . This book was released on 1994 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: An X-ray diffraction (XRD) method was developed to quantify the crystallographic character of coatings for implants in terms of phases present and amount of amorphous calcium phosphate or micro-crystalline phases included. This method requires only information from the Joint Committee for Powder Diffraction Standards (JCPDS) files, does not require the use of admixed standards, and automatically takes into account and corrects for the variations in crystallite sizes of component phases. This method employs an algorithm based on real XRD optics and not a statistical fit. The residual information from convoluted peaks after defining one or more of them using the algorithm gives the basic data for further deconvolution of any remaining peaks and a quantitative assessment of the phases present which they represent. Usually an explanation of variance greater than 95% is achieved for the deconvoluted modeled profiles. The method is robust. The overall deconvolution of the peaks of all crystalline phases present from the total XRD profile gives the profile and quantification of any amorphous or micro-crystalline phase present. The reliability of this method was demonstrated by analyses of admixtures from three different laboratories and comparison of results on the same coatings from two different laboratories.

Download or read book Quantitative X Ray Diffractometry written by Lev S. Zevin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important techniques for determining the atomic structure of a material is X-ray diffraction. One of the great problems of the technique, however, is the fact that only the intensity of the diffraction pattern can be measured, not its phase. The inverse problem, of determining the structure from the pattern thus contains ambiguities that must be resolved by other means. Quantitative X-ray analysis provides one way to resolve this phase problem: mixing the material in question with a material of known structure yields interferences that can be analyzed to yield the unknown phases. Invented in 1916, but little used at the time, the technique has seen a recent revival due to the development of extremely precise X-ray diffractometers coupled with powerful computers.

Download or read book Ion Substituted Calcium Phosphates Coatings written by Gabriela Graziani and published by MDPI. This book was released on 2021-01-28 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coatings based on hydroxyapatite and calcium phosphates have a significant relevance in several research fields, such as biomaterials, cultural heritage, and water treatment, due to their characteristic properties. Hydroxyapatite can easily accommodate foreign ions, which can either be incorporated into the lattice, thanks to its specific lattice characteristics, or be adsorbed onto its surface. All these substitutions significantly alter the morphology, lattice parameters, and crystallinity of hydroxyapatite so they influence its main properties. These ion substitutions can be sought or can derive from substrate contaminations, which is an important aspect to be evaluated. Finally, this capability can be used to obtain hydroxyapatites with specific properties, such as antibacterial characteristics, among others. For these reasons, the aim of this Special Issue is to document current advances in the field of ion-substituted hydroxyapatites and highlight possible future perspectives regarding their use. Contributions in the form of original articles and review articles are presented, covering different areas of application.

Download or read book Modern Powder Diffraction written by David L. Bish and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 20 of Reviews in Mineralogy attempted to: (1) provide examples illustrating the state-of-the-art in powder diffraction, with emphasis on applications to geological materials; (2) describe how to obtain high-quality powder diffraction data; and (3) show how to extract maximum information from available data. In particular, the nonambient experiments are examples of some of the new and exciting areas of study using powder diffraction, and the interested reader is directed to the rapidly growing number of published papers on these subjects. Powder diffraction has evolved to a point where considerable information can be obtained from ug-sized samples, where detection limits are in the hundreds of ppm range, and where useful data can be obtained in milliseconds to microseconds. We hope that the information in this volume will increase the reader's access to the considerable amount of information contained in typical diffraction data.
Download or read book X Ray Diffraction for Materials Research written by Myeongkyu Lee and published by CRC Press. This book was released on 2016-02-22 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray diffraction is a useful and powerful analysis technique for characterizing crystalline materials commonly employed in MSE, physics, and chemistry. This informative new book describes the principles of X-ray diffraction and its applications to materials characterization. It consists of three parts. The first deals with elementary crystallography and optics, which is essential for understanding the theory of X-ray diffraction discussed in the second section of the book. Part 2 describes how the X-ray diffraction can be applied for characterizing such various forms of materials as thin films, single crystals, and powders. The third section of the book covers applications of X-ray diffraction. The book presents a number of examples to help readers better comprehend the subject. X-Ray Diffraction for Materials Research: From Fundamentals to Applications also • provides background knowledge of diffraction to enable nonspecialists to become familiar with the topics • covers the practical applications as well as the underlying principle of X-ray diffraction • presents appropriate examples with answers to help readers understand the contents more easily • includes thin film characterization by X-ray diffraction with relevant experimental techniques • presents a huge number of elaborately drawn graphics to help illustrate the content The book will help readers (students and researchers in materials science, physics, and chemistry) understand crystallography and crystal structures, interference and diffraction, structural analysis of bulk materials, characterization of thin films, and nondestructive measurement of internal stress and phase transition. Diffraction is an optical phenomenon and thus can be better understood when it is explained with an optical approach, which has been neglected in other books. This book helps to fill that gap, providing information to convey the concept of X-ray diffraction and how it can be applied to the materials analysis. This book will be a valuable reference book for researchers in the field and will work well as a good introductory book of X-ray diffraction for students in materials science, physics, and chemistry.
