Effect of the replacement of kaolin by kaolin residue on the production of ceramic. 2007. 78 f. Dissertação (Mestrado em Tecnologia de Materiais; Projetos Mecânicos; Termociências) - Universidade Federal do Rio Grande do Norte, Natal, 2007.https://repositorio.ufrn.br/jspui/handle/123456789/15551Companies involved in kaolin mining and treatment represent an important area of industrial development in Brazil, significantly contribution to the worldwide production of such mineral. As a result, large volumes of kaolin residue are constantly generated and abandoned in the environment, negatively contributing to its preservation. In this scenario, the objective of the present study was to characterize the residue generated from kaolin mining as well as to assess its potential use as raw material for the production of ceramic tiles. Ceramic mixtures were prepared from raw materials characterized by X-ray fluorescence, X-ray diffraction, particle size analysis and thermal analysis. Three compositions were prepared using kaolin residue contents of 10%, 20% and 30%. Samples were uniaxially pressed, fired at 1200ºC and characterized aiming at establishing their mineralogical composition, water absorption, apparent porosity, specific mass, linear retraction and modulus of rupture. The results showed that the residue basically consisted of kaolinite and successfully replaced raw kaolin in the preparation of ceramic title formulations without significantly affecting the properties of the fired materialapplication/pdfAcesso AbertoResíduo de caulimReciclagemCaulimMatéria-primaCerâmicakaolin residueRecyclingCeramic raw materialCeramicmasterThesisCNPQ::ENGENHARIAS::ENGENHARIA MECANICA
