Resumo: | Porcelain are multiphased materials produced from natural raw material. They basically consist of kaolin, feldspar and quartz and/or alumina. It is during the sintering process that there are several chemical reactions, being affected by the temperature, time, oven atmosphere and composition of the ceramic mass. When sintered the phases present are the vitreous matrix and the crystalline phase, composed by mullite, quartz and alumina. That a small modification as much concerning in the composition from raw material a ceramic mass, may change the properties from porcelain, were addition to the mixture containing 10% of clay, 25% kaolin, 35% feldspar and 30% of alumina, quantities individually the 5% and 10% respectively the ZnO(pec) and Fe2O3(pec) originating from citrus pectin and zinc and iron nitrate respectively, and the full replacement of commercial alumina by Al2O3(pec) originating from citrus pectin and aluminum nitrate. However both originated from pectin citrus gelation plus salt the intended respective metal source. These oxides have a particular physical characteristic as high softness and high porosity. The mixture of these oxides together with the ceramic mass, which were mixed wet in balls mill, and dried in stove. The resulting powders from these mixtures were pressed and sintered. The sintered porcelains were characterized by apparent density measurement, water absorption, linear contraction, porosity percentage, Xray diffraction, scanning electron microscope, EDS microanalyses and rupture module by three points flexion. These oxides, reduced the values of the modules of rupture. Nevertheless for the major of the samples the sintering emperature was reduced. It was verified that these oxides actuate directly on the formation of the liquid stage, and it is this stage that during the sintering, modifies the other present stage and then, modify the microstructure and consequently the mechanical characteristics of the porcelain. |

Basicamente são formadas por caulim, feldspato e quartzo e/ou alumina. É durante o processo de sinterização que ocorrem diversas reações químicas, sendo essas afetadas pela temperatura, tempo, atmosfera do forno e composição da massa cerâmica. Quando sinterizadas as fases presentes são a matriz vítrea e a fase cristalina composta por mulitas e quartzo e/ou alumina. Sabendo que uma pequena modificação na massa cerâmica pode alterar as propriedades das porcelanas, foram adicionados à mistura contendo 10% de argila, 25% de caulim, 35% de feldspato e 30% de alumina, individualmente quantidades de 5% e 10% respectivamente de ZnO(pec) e Fe2O3(pec) originários da pectina cítrica e nitrato de zinco e ferro respectivamente, e a substituição integral da alumina comercial por Al2O3(pec) originário da pectina cítrica e nitrato de alumínio, estes óxidos foram produzidos a partir da gelificação da pectina cítrica e nitrato de respectivo metal de interesse. Os óxidos obtidos são de elevada maciez e alta porosidade. A mistura destes óxidos junto a massa cerâmica foi realizada a úmido em moinho de bolas e secos em estufa. Os pós resultantes destas misturas foram prensados e sinterizados. As porcelanas sinterizadas foram caracterizadas através de medidas de densidade aparente, absorção de água, retração linear, porcentagem de porosidade, difratometria de raios X, microscopia eletrônica de varredura, microanálise via EDS e módulo de ruptura por flexão em três pontos. Estes óxidos diminuem os valores do módulo de ruptura. Porém para a maioria das amostras, a temperatura de sinterização diminui. Foi verificado que estes óxidos atuam diretamente na formação da fase líquida, modificam as demais fases presentes e assim, alteram a microestrutura e consequentemente afetam as propriedades mecânicas da porcelana.Submitted by Fabiano Jucá (fjuca@unicentro.br) on 2021-04-30T12:22:12Z No. of bitstreams: 1 Tese ALDO PRZYBYSZ.pdf: 8040283 bytes, checksum: f48cef45814cb67d006a7a076f1259de (MD5)Made available in DSpace on 2021-04-30T12:22:12Z (GMT).
