“…The decay and disappearance of mineral phases contributes decisively to the formation of glass, up to 835 ºC, and new minerals were form such as: ferrosilite, forsterite, augite, fayalite or olivine. Amorphous material was decanted from a microcrystalline mass to a porous zone which tends to be filled up with glass (Jordan et al, 2008). At 1080 ºC mullite was formed in A, C and D series.…”

Four kaolin deposits from Cauquenes Province in the VII Region of Maule were studied. Kaolins were moistened until homogeneous agglomerates with 5% of water were obtained. They were pressed (300 kg/cm 2 , 80 x 40 x 5 mm). The pieces were finally heated. The mineralogical analysis of the fired bodies was carried out by XRD at the following temperatures 835, 980, 1080 and 1160 ºC. Results show the presence of quartz, mullite, spinel, orthoclase, albite, hematite, enstatite, ferrosilite, augite and forsterite for A samples. Quartz, trydimite, anorthite, orthoclase, hematite, corundum, fayalite, ferrosilite and hercynite were present in B samples. Quartz, anorthite, albite, hematite, mullite, microcline, augite and enstatite were present in C kaolin samples. Quartz, mullite, spinel, orthoclase, trydimite, enstatite and olivine were present in D samples. The persistence of illite at least at 835 ºC is shown in all samples. At 1080 ºC mullite is formed in A, C and D series. In these series mullite content is high at 1160 ºC. The samples studied are easily adaptable to ceramic processes (pottery, sanitary, structural ceramic, bricks, etc).

“…Já quando o processo de conformação usado foi a extrusão, os valores se apresentaram acima do mínimo de referência a partir da temperatura de queima de 800 ºC, independentemente da argila utilizada no processo. Os resultados obtidos vão ao encontro de trabalhos apresentados na literatura [23,24], utilizando massas para cerâmica vermelha. Nesses estudos observou-se que as peças conformadas com as massas com maiores quantidades de óxidos fundentes apresentaram maiores densificação e resistência mecânica.…”

ResumoAs propriedades dos produtos cerâmicos estão intimamente relacionadas às características iniciais das matérias-primas, mas também aos parâmetros e condições de processamento. Dentro desse contexto, este trabalho teve como objetivo avaliar a influência das características de argilas e sua interação com as variáveis de processamento sobre as propriedades tecnológicas de corpos de prova. Foram utilizadas argilas provenientes dos estados de Pernambuco e da Paraíba. As argilas foram beneficiadas e em seguida submetidas a ensaios de caracterização. Os corpos de prova foram conformados por prensagem e por extrusão, secos a 110 ºC e em seguida submetidos à queima nas temperaturas de 800, 900, 1000, 1100 e 1200 ºC com taxa de aquecimento de 5 ºC/min e tempo de queima de 60 e 180 min. Em seguida foram avaliadas as propriedades tecnológicas (retração linear de queima, absorção de água e resistência à flexão em três pontos) e as fases formadas para os diferentes tratamentos térmicos. Pôde-se concluir que a interação das características granulométricas, mineralógicas e químicas, assim como os parâmetros de processamento, principalmente o método de conformação, são determinantes para as propriedades tecnológicas da peça cerâmica. Palavras-chave: argilas, parâmetros de processamento, propriedades tecnológicas.

“…Through the ceramic process, once the crystalline structures of these minerals exceed their stability limits, they are partially decomposed while simultaneously others are being formed. The destruction of the pre-existing structure does not occur instantaneously (Jordán et al, 2008). The knowledge of the origin, diagenesis and physicochemical composition of the clays is essential in order to search suitable compositions when these are required for ceramic production (Sanfeliu, 1987 andSanfeliu andJordán.…”

The general characteristics and technological properties of ceramic clays used in the Spanish ceramic cluster (Castellón province), have been investigated. Red clays for ceramic wall tiles and floor tiles are mainly extracted in the Valencian Community, in Villar del Arzobispo, La Yesa, Chulilla, Alcora (Más Vell) and San Juan de Moró, although there is a small proportion coming from Teruel province. An important group of clay raw materials used in the ceramic cluster of Castellón, in Spain, occurs in Permo-Triassic, Cretaceous and Tertiary sediments. These clays are intended for applications in stoneware. Clays were analyzed by X-ray diffraction, chemical composition, particle size distribution, thermal analysis and plasticity. Ceramic bodies were fired at temperatures varying from 850 to 1150ºC to determine the linear shrinkage, water absorption and flexural rupture strength.
