Synthesis of Cordierite-Based Ceramics : monograph

Abstract

Advanced ceramic materials include a large number of new materials, which are very different by their nature. These materials are the result of the demands of modern technologies for operation at high temperatures and pressures. Modern ceramic materials, opposite to classical ones, are materials with a clearly defined composition and structure, with optimal mechanical, thermal, chemical, and electrical properties, suitable for a specific purpose in accordance with the requirements of modern technologies. Cordierite-based ceramics, with the basic chemical composition of MgO-Al2O3-SiO2, are widely used in various fields, from substrates for microelectronic packaging industry to cookware, heat exchangers, glazes for floor tiles, etc. Owing to their low-temperature thermal expansion coefficient and low relative dielectric constant, these ceramic materials are also well-known by their good thermo-mechanical, chemical, and dielectric properties. Therefore, they can be applicable as materials exposed to sudden temperature changes and also as semiconductor carriers. In this monograph, modern principles of the synthesis of cordieritebased ceramics are discussed. They start from the analysis of single, binary, and ternary systems, followed by properties of cordierite-based ceramics, principles of mechanochemistry and mechanical activation as a method for powder preparation, sintering as a method of obtaining the ceramics, possible processes for obtaining cordierite-based ceramics, and finally, presents the author’s latest results, which are thoroughly commented. At the end, a short overview is given and some future trends are discussed, as well.

Research presented in this monograph was performed within the projects OI 172057, 142011 G, and 1832 funded by the Ministry of Education, Science and Technological Development of the Republic of Serbia.
