Book Synopsis Contribution à l'étude de la carbonisation et de la graphitation de mélanges constitués d'un liant à base de brai de houille et de carbone granulaire by : Vincent Clausse
Download or read book Contribution à l'étude de la carbonisation et de la graphitation de mélanges constitués d'un liant à base de brai de houille et de carbone granulaire written by Vincent Clausse and published by . This book was released on 2005 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse est consacré à l'étude du traitement thermique de tubes d'échangeur de chaleur en céramique noire et à leurs caractérisations. Dans les tubes étudiés, du soufre est ajouté en quantité contrôlée au brai afin d'accroître les propriétés mécaniques du tube. Cet élément modifie fortement l'évolution du liant lors du traitement thermique (forte diminution de la perte de masse). De plus, pour une concentration massique en soufre dans le liant cru supérieure à 10%, la graphitation des semi-cokes est fortement limitée par la réticulation des molécules mésogènes par le soufre. L'étude de la cuisson des tubes a mis en évidence une forte influence de la température finale de traitement sur les propriétés des tubes, tandis qu'aucune influence de la loi de chauffe n'a été observée. De plus il est apparu que l'orientation des grains constituant la charge conditionne fortement les caractéristiques des tubes.

This book was released on 1995 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL, QUI S'INSCRIT DANS LE CADRE DE RECHERCHES A FINALITES APPLIQUEES, VISE A MIEUX COMPRENDRE LES PHENOMENES PHYSICO-CHIMIQUES QUI CONTROLENT ET FAVORISENT LE DEVELOPPEMENT DES TEXTURES ANISOTROPES LORS DE L'ELABORATION DES GRAPHITES ARTIFICIELS. POUR CELA, NOUS AVONS ETUDIE LES INTERACTIONS DE BRAIS DE HOUILLE AVEC DIFFERENTS TYPES DE GRAPHITE PULVERULENT EN ANALYSANT LES MATERIAUX OBTENUS AU COURS DU TRAITEMENT THERMIQUE. LES MELANGES DE DEPART BRAI-GRAPHITE ONT ETE CARACTERISES PAR LEURS PROPRIETES RHEOLOGIQUES. L'ADDITION DE GRAPHITE DANS LA MATRICE DE BRAI CONDUIT A UNE AUGMENTATION DE LA VISCOSITE DU MILIEU. PAR AILLEURS, L'ANALYSE RHEOLOGIQUE MET EN EVIDENCE LA FIXATION DE FRACTIONS LOURDES DU BRAI A LA SURFACE DES PARTICULES DE GRAPHITE. L'EFFET DE CHARGE SUR L'EVOLUTION THERMIQUE DU BRAI ENTRAINE UNE MODIFICATION IMPORTANTE DU MECANISME DE DEVELOPPEMENT DE LA MESOPHASE. L'ORIENTATION PREFERENTIELLE DES ESPECES LES PLUS LOURDES DU BRAI A LA SURFACE DU GRAPHITE CONDUIT A UNE DEMIXTION DE PHASES. CELLE-CI SE TRADUIT NOTAMMENT PAR L'APPARITION D'UNE PHASE ANISOTROPE ASSOCIEE AU GRAPHITE QUI INDUIT UNE PREORIENTATION STRUCTURALE DU MATERIAU. L'ANALYSE DE L'APTITUDE A LA GRAPHITATION DES SYSTEMES BRAI-GRAPHITE MET EN EVIDENCE UN EFFET DE MEMOIRE DU PHENOMENE D'ORIENTATION INDUITE QUI SE TRADUIT PAR UNE GRAPHITATION A PLUS BASSE TEMPERATURE EN PRESENCE DE PARTICULES DE GRAPHITE. CET EFFET EST D'AUTANT PLUS FORT QUE L'ANISOTROPIE DES PARTICULES DE GRAPHITE EST IMPORTANTE. IL EST EGALEMENT LIE AU TAUX DE CHARGE, L'ORIENTATION A LONGUE DISTANCE SE MANIFESTANT PAR UNE TENEUR OPTIMALE DE GRAPHITE DANS LE MILIEU

Book Synopsis Science et technique des carbones : de l’énergie aux matériaux by : DELHAES Pierre
Download or read book Science et technique des carbones : de l’énergie aux matériaux written by DELHAES Pierre and published by Lavoisier. This book was released on 2012-11-21 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’atome de carbone a un rôle clé. Il peut former plusieurs types de liaisons chimiques mais également s’auto-associer pour donner un squelette carboné, caractéristiques qui sont à la base de la chimie organique, de la biochimie et de la vie. Science et technique des carbones présente la progression des connaissances dans les solides carbonés à partir des découvertes et inventions successives depuis la préhistoire. Le rôle essentiel joué par l’exploitation des mines de charbon au moment de la première révolution industrielle comme source d’énergie primaire est un point crucial. L’importance du carbone s’est accrue par le développement de la carbochimie pour créer des matériaux artificiels. Leurs utilisations comme matériaux traditionnels de transformation en sidérurgie et comme céramiques particulières, puis technologiques (charbons actifs, fibres de carbone…), sont successivement décrites. La découverte récente des carbones moléculaires, fleurons de la nanotechnologie, met en exergue l’avènement de la technoscience. Finalement, leur impact économique et sociétal est analysé en exposant l’existence de grandes transitions énergétiques associées aux cycles macro-économiques.
Book Synopsis Carbon-based Solids and Materials by : Pierre Delhaes
Download or read book Carbon-based Solids and Materials written by Pierre Delhaes and published by John Wiley & Sons. This book was released on 2013-02-07 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that solid carbons can be found in various guises with different forms of bulk phases (graphites, diamonds and carbynes) as well as more molecular forms (fullerenes,nanotubes and graphenes) resulting from recent discoveries. The cause of this rich polymorphism is analyzed in the first part of this book (chapters 1-5) with the propensity of carbon atoms for forming different types of homopolar chemical bonds associated with variable coordination numbers. Precursor organic molecules and parent compounds are also described to establish specific links with this rich polymorphism. Then in a second part (chapters 6-10) a comparative review of the main classes of bulk physical properties is presented. This approach emphasizes in particular the electronic behavior of (pi) polyaromatic systems organized in plane and curved atomic sheets. Finally in a third part (chapters 11-15) the surface and interface characteristics are introduced together with the texture and morphology of these multiscale carbon materials. An overview of the main field of applications is related showing the large use and interest for these solids.
Book Synopsis Carbon Science and Technology by : Pierre Delhaes
Download or read book Carbon Science and Technology written by Pierre Delhaes and published by John Wiley & Sons. This book was released on 2012-12-13 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon solids have been utilized by man since prehistoric times, first as a source of heat and then for other purposes; these are used as key markers for different civilizations. The essential role played by the use of coal mines during the industrial revolution as a main source of energy is a crucial point, which was then expanded through the development of carbochemistry. This book begins by describing the use of solid carbons as traditional materials, for example in the steel industry and for ceramics, then moving on to their technological uses such as active carbons and carbon fibers, etc., before discussing nanocarbons, the jewel in the crown of contemporary technological science. The final chapter analyzes the current economic and social impact of carbon solids.
