This book was released on 1986 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional ceramic processing normally consists of two stages: first, a powder having the desired physical and chemical characteristics is prepared, then it is heated to promote interparticle bonding (sintering) and densification. This generally requires high temperature (1200-2000'C) and controlled atmospheres (vacuum - high pressure). Often the sintering stage may require up to several days to carry out. An alternative method termed 'Self-Propagating High-Temperature Synthesis (SHS) is described in this review. The process utilizes the heat generated by an exothermic reaction between precursor components to densify the resulting reaction products. The heat generated by these reactions is capable of producing temperatures in excess of 2500'C. Since the heat is 'self-generated, ' high temperature furnaces are not required. Processing times are on the order of seconds/minutes rather than hours/days as in conventional processes. In addition to these attributes, products produced by SHS to be of higher purity than the starting materials since the high temperatures vaporize the volatile contaminants. Further, intractable borides and carbides can be produced by this technique.

Book excerpt: Self-Propagating High-Temperature Synthesis of Materials is a collection of papers that reflects modern trends in self-propagating, high-temperature synthesis (SHS), a process for synthesis of modern materials carried out in the mode of autowave solid-flame combustion. To date, SHS-produced materials have found their application in different branches of modern science and technology, mechanical engineering, ferrous and nonferrous metallurgy, aerospace engineering, chemical industry, electrical engineering, and electronics. This book is useful not only for the SHS community, but also for researchers and engineers who are active in the following related fields of knowledge; theory and practice of combustion, materials science and technology, pure and applied chemistry, and metallurgy.

Download or read book Self propagating High Temperature Synthesis SHS of Semi conducting Chevrel Phase Compounds written by Milind Mansing Pawar and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chevrel phase compounds (MxMo6S8-CPs) constitute a class of multifunctional material which attracted significant attention for catalysis, battery material and quantum computing. Multifunctionality of these materials is based on unique structure of Mo6S8 building block which allows intercalation of over 40 ternary elements. Such versatility of the structure creates wide range of chemistries that lead to superatomic ordering. The main limitation to utilize is processing of these compounds in reproducible manner. In this work a novel synthesis process called self-propagating high temperature synthesis (SHS) has been used. We have demonstrated processing of sulfide-Chevrel phase compounds with semiconducting properties for the first time. The reaction mechanism involved in SHS of CPs is studied to understand the kinetic processes associated with the spontaneous combustion of the precursors at a given (ignition) temperature. Precursor size, mixing, and ignition temperature of the reaction affect the synthesis time and yield of the final products. Revised criteria for the initiation of SHS has been proposed. It was found that reaction for the mixture of xM: 2Mo: 4MoS2 via SHS can be initiated below melting point of lowest melting point component system. This new finding can open new avenues for SHS synthesis as it allows material processing via SHS at relatively lower temperature with complete transformation in short duration of time. Fastest recorded synthesis for Chevrel phase compound was achieved in just one minute of direct exposure to 1050 oC in a quartz reaction chamber under vacuum. Ultra-fast nature of phase transformation was attributed to novel concept of “Intercalation Assisted Massive Phase Transformation”. The semiconducting Sulfide-Chevrel phase produced in this research work includes: Cu4Mo6S8, Ni2Mo6S8 and Fe2Mo6S8. Respective optical bandgaps were estimated to be 1.67 eV, 1.74 eV and 1.63 eV. Sulfide-CPs exhibited favorable bandgap in Visible-light activated range. This was verified with Ni2Mo6S8 synthesized via SHS for photo-oxidative desulfurization of thiophene in n-Octane with 100 ppm of sulfur concentration. Complete removal of sulfur containing thiophene from n-Octane was reported after 2 hours of visible light irradiation.
