Third millenium ideal gas and condensed phase thermochemical database for combustion (with update from active thermochemical tables).

The thermochemical database of species involved in combustion processes is and has been available for free use for over 25 years. It was first published in print in 1984, approximately 8 years after it was first assembled, and contained 215 species at the time. This is the 7th printed edition and most likely will be the last one in print in the present format, which involves substantial manual labor. The database currently contains more than 1300 species, specifically organic molecules and radicals, but also inorganic species connected to combustion and air pollution. Since 1991 this database is freely available on the internet, at the Technion-IIT ftp server, and it is continuously expanded and corrected. The database is mirrored daily at an official mirror site, and at random at about a dozen unofficial mirror and 'finger' sites. The present edition contains numerous corrections and many recalculations of data of provisory type by the G3//B3LYP method, a high-accuracy composite ab initio calculation. About 300 species are newly calculated and are not yet published elsewhere. In anticipation of the full coupling, which is under development, the database started incorporating the available (as yet unpublished) values from Active Thermochemical Tables. The electronic version now also contains an XML file of the main database to allow transfer to other formats and ease finding specific information of interest. The database is used by scientists, educators, engineers and students at all levels, dealing primarily with combustion and air pollution, jet engines, rocket propulsion, fireworks, but also by researchers involved in upper atmosphere kinetics, astrophysics, abrasion metallurgy, etc. This introductory article contains explanations of the database and the means to use it, its sources, ways of calculation, and assessments of the accuracy of data

Combustion of pulverized coal in counter-current flow

The project objective is to develop and investigate pulverized coal combustors operating in counter-current flow. In the first year of the project our activity was focused on: (a) design, calculation and fabrication of a prototype of the combustor for atmospheric pressure operation, (b) purchase and fabrication of the measuring instruments and preparation of the facilities for experiments, (c) performing the experiments with the combustor firing bituminous coals (including a coal delivered from the USA), and (d) theoretical - predictive work

Elektrolytische Abscheidung von Oxidkeramikschichten aus Substraten aus nichtoxidischer Keramik. Jahresbericht Materialforschung 1991

The objectives of the present research are to investigate formation of monolithic as well as composite and alloy oxide coatings on non-oxide ceramics, using the electrochemical coating method. In addition, the chemical and physics compatibility of the different non-oxide substrates with the oxide coatings subjected to high temperature treatments will be characterized through microstructural evolution in these systems. Five different non-oxide ceramics including three carbides (SiC, TiC, B_4C), a boride (TiB_2) and a nitride (TiN) were chosen as the substrate materials. ZrO_2, Al_2O_3 and Cr_2O_3 were chosen as the monolithic ceramic coatings, where alloys of their binary systems will be used as a ceramic composite (ZrO_2-Al_2O_3) and a ceramic alloy (Al_2O_3-Cr_2O_3) coating.

Microstructure and chemistry of stable interface configurations in thin oxide films Final report

The control of ceramic interface structures and properties is the key to the development of useful ceramic materials for both structural and functional applications in engineering systems. Oxide ceramics are by far the most important class of these materials, primarily because of their unique combination of availability and chemical stability, and of the commercially important oxide ceramics, alumina still accounts for the largest share of the market. In effect alumina is to ceramics what steel is to metallic alloys and silicon to semiconductor technology. Alumina has always been a focus of interest for our ceramics research group in the Faculty of Materials Engineering at the Technion. Initially, some 20 years ago, the focus was on alumina as a component of armor systems intended for protection against both light and medium ballistic threats. More recently, interest shifted to some novel processing routes for alumina ceramics, especially direct metal oxidation (popularly known as the Lanxide process). The present project is the last in a series of three funded programs. The first, which was funded by the Volkswagen Foundation, was devoted to a study of the structure of grain boundaries in #alpha#-Al_2O_3, the stable corundum phase. This work was later extended into an unfunded project on nanocomposite aluminas based on the occlusion of small SiC particles in the alumina grains. In parallel, AFIRST (the Franco-Israel funding agency) supported a project on the development of damage tolerant, laminated alumina systems, itself an extension of earlier work on highly textured alumina which was supported by the Atochem company in France. The AFIRST work culminated in the development of gel-casting for the production of oxide ceramic laminates in which the thin, highly textured alumina layers provide both strength and damage tolerance. These materials are based on matrices of reaction bonded alumina (BRAO), reaction bonded mullite (BRRBM), or alumina toughened zirconia (ATZ), all three of which are high performance ceramics in their own right.
