Download or read book Investigation of Porous Glasses Based on Sodium-borosilicate Glass System written by Muhammad Hasanuzzaman and published by . This book was released on 2013 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work investigated the development of porous glasses by making additions of zirconia (ZrO2) and zircon (ZrSiO4) to the sodium borosilicate glass system SiO2-B2O3-Na2O. Additions of Zr-based compounds were made in an attempt to yield more alkaline durable porous glasses compared to the silica-rich porous glass structures of the parent sodium borosilicate glass system. Glasses were fabricated using a high-temperature fusion process. X-ray diffraction (XRD) was used to confirm that the glasses were amorphous upon pouring from the melt. The glasses were characterised using differential thermal analysis (DTA) to identify important thermal events, including the glass transition temperature (Tg) and crystallisation temperature (Tx). The occurrence of amorphous phase separation was key to the formation of two-phase glasses and ultimately porous glasses. It was found that the quantity of sodium oxide (Na2O) in the glass composition played an important role in determining whether phase separation occurred via nucleation and growth or spinodal decomposition. Based on the DTA data, a heat treatment temperature of 650 °C was selected for three different durations (14, 24 and 63 hours). The heat-treatment caused the glasses to phase separate into two phases; a silica-rich phase and a sodium borate phase. The sodium borate phase coarsened as a function of heat-treatment time. Fourier transform infrared (FTIR) spectroscopy, together with XRD, was found to be effective as a means of comparing the phase separation and crystallisation characteristics. Glasses heat-treated for longer times showed some evidence of crystal formation. Having formed two-phase glass, acid leaching was used to remove the borate phase and create a porous structure. The leaching process had to be carefully controlled in terms of acid type, acid concentration, leaching time and leaching temperature. For all glasses, a post-leach alkali wash step was needed to remove trapped silica gel. The porous glasses comprised a silica-rich porous skeleton. Scanning electron microscopy (SEM) revealed classic interconnected porous morphologies. The most consistent and best-defined morphologies were observed for the zircon-containing glass. Energy dispersive X-ray (EDX) analysis confirmed the presence of zirconium (Zr) in the porous silica-rich skeleton. Mercury intrusion porosimetry (MIP) was used to characterise the pore characteristics and measure pore volume, pore size, pore distribution, total pore surface area, and bulk and apparent density. In general, the porous glasses exhibited sharp, unimodal pore distributions, but there was also evidence of micropores, believed due to residual silica gel. Mean pore size ranged from 40 nm to 200 nm for the different porous glasses studied. It was observed that mean pore size linearly increased with square root of the heat-treatment time. Total pore surface area increased with decreasing size of pores and ranged from 5 to 35 m2/g depending on glass composition and heat-treatment time. Alkaline resistance tests were carried out. Zircon- and zirconia-containing porous glasses are 3-4 times more alkali durable than the parent sodium borosilicate glass.

Available in PDF, EPUB and Kindle. Book excerpt: This is an advanced text on the microstructure and properties of materials, the first volume of a possible 3-volume set. While there are many elementary texts in materials science, there are very few advanced texts. Chapter 1 on aluminum alloys presents microstructural optimization and critical considerations in design applications. Chapter 2 on Nickel-base superalloys reviews the compositional, microstructural and processing advances in increasing their maximum use temperature. Chapter 3 on metal matrix composites discusses the strengthening mechanisms of metals dispersed with short fibers or particles. Chapter 4 on polymer matrix composites contains the details of the microsturcture property relationships of high performance fibers, polymer matrix material and the advanced composites made therewith. Chapter 5 on ceramics matrix composites describes the fibers and matrix materials used, the processing techniques involved and the mechanical properties under different loading conditions. Chapter 6 on inorganic glasses describes the influence of second phases, both glassy and cyrstalline on their properties. Chapter 7 on superconducting materials shows the importance of twins, grain boundaries, dislocations and stacking faults. Chapter 8 on magnetic materials introduces the domain structure and its effects on the soft and hard magnetic properties.

This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterization of materials and phenomena has historically been the principal limitation to the development in each area of science. Once what we are observing is well defined, a theoretical analysis rapidly follows. Modern theories of chemical bonding did not evolve until the methods of analytical chemistry had progressed to a point where the bulk stoichiometry of chemical compounds was firmly established. The great progress made during this century in understanding chemistry has followed directly from the development of an analytical chemistry based on the Dalton assumption of multiple proportions. It has only become apparent in recent years that the extension of our understanding of materials hinges on their non-stoichiometric nature. The world of non-Daltonian chemistry is very poorly understood at present because of our lack of ability to precisely characterize it. The emergence of materials science has only just occurred with our recognition of effects, which have been thought previously to be minor variations from ideality, as the principal phenomena controlling properties. The next step in the historical evolution of materials science must be the development of tools to characterize the often subtle phenomena which determine properties of materials. The various discussions of instrumental techniques presented in this book are excellent summaries for the state-of-the-art of materials characterization at this rather critical stage of materials science. The application of the tools described here, and those yet to be developed, holds the key to the development of this infant into a mature science.

This book was released on 2015-11-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise and inexpensive introduction for an undergraduate course in glass science and technology. The level of the book has deliberately been maintained at the introductory level to avoid confusion of the student by inclusion of more advanced material, and is unique in that its text is limited to the amount suitable for a one term course for students in materials science, ceramics or inorganic chemistry. The contents cover the fundamental topics of importance in glass science and technology, including glass formation, crystallization, phase separation and structure of glasses. Additional chapters discuss the most important properties of glasses, including discussion of physical, optical, electrical, chemical and mechanical properties. A final chapter provides an introduction to a number of methods used to form technical glasses, including glass sheet, bottles, insulation fibre, optical fibres and other common commercial products. In addition, the book contains discussion of the effects of phase separation and crystallization on the properties of glasses, which is neglected in other texts. Although intended primarily as a textbook, Introduction to Glass Science and Technology will also be invaluable to the engineer or scientist who desires more knowledge regarding the formation, properties and production of glass.
