Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 38 (Septembre 2012) . - pp. 12294-12298 Titre : Crystallization and coarsening kinetics of rutile phase in modified Ti - bearing blast furnace slag Type de document : texte imprimé Auteurs : Zhang Wu, Auteur ; Zhang Li, Auteur ; Zhang Ju-hua, Auteur Année de publication : 2012 Article en page(s) : pp. 12294-12298 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Blast furnace slag Slag Kinetics Crystallization Résumé : Crystallization and coarsening kinetics of nonisothermal precipitation process of rutile in modified Ti-bearing blast furnace slag were discussed. The modified slag was analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM) and EDX. The experimental results showed that the cooling rate has an important effect on precipitation of the rutile phase. Low cooling rate is in favor of the increase in the volume fraction of rutile phase in Ti-bearing blast furnace slag and the growth of rutile phase. The volume fraction of rutile phase was approximately described by JMAK equation. The experiential expression of average crystal radius for rutile phase was also obtained.
