“…On comparing the FTIR spectra of PET film to metalized PET films, several new peaks which indicated chemical interaction between PET and metal (Al) have been observed. A sharp and low intensity band at 640 cm−1 in FTIR spectra of metalized PET films is attributed to Al-O stretching [29]. A sharp band around 960 cm−1 could be assigned to longitudinal stretching vibrations of Al-O [30].…”

Commercially available polyethylene terephthalate (PET) film of thickness of 20 μm has been used as flexible substrate and aluminum has been coated on PET film using vacuum thermal evaporation method. The structural characterization of Al-PET film has been done using X-ray diffraction (XRD) pattern and Fourier transform infrared (FTIR) spectroscopy. Mechanical study of Al-PET film has been carried out using Dynamic Mechanical Analyzer (DMA). The glass transition temperature (T g) of Al-PET film is found to be 112.3°C whereas T g of commercial PET film is 89.7°C. The result of stress-strain behavior of polymer films for a wide range of temperatures is useful for engineering applications therefore in the present work an effort has been made to see the effect of wide range of temperatures on metalized polymer. The stress-strain curves of Al-PET film at room and elevated temperatures explain the mechanical response of this film under the applied load.

“…Lowest MOR was presented for the shaped ceramic with the minimum percentage of vitreous phase (Table III), which was slip casting sample. There are previous studies done about the correlation between the bending strength and the vitreous phase content, where it is maintaining standarddeviation that is inherent to ceramic materials [10,13,24,25]. At 1400 °C bending strength decreased abruptly for extruded and laminated samples.…”

The results of qualitative and quantitative properties of clay based ceramic are presented in this work. Four different shaping methods and sintering temperatures were used to understand their influence in the final properties of a ceramic material formulated using kaolinite clay and calcined alumina. This material can be used as a structural ceramic for different applications, and there is no pre-established relation between the forming method and the final sintered properties. Forming methods used to prepare the samples were uniaxial pressing (a batch process that allows application in dry samples), extruding (a continuous process that requires moisture), slip casting (a process that allows to shape complex ceramic ware), and lamination (a batch process that requires moisture). Sintering temperatures were in the range of 1100 and 1400 °C. In order to compare how properties behave as the shaping method and sintering temperature change, textural properties, shrinkage, porosimetry, phase composition and mechanical strength were evaluated and analyzed. Scanning electron microscopy and microtomography were employed for analyzing and comparing the developed microstructures. Differences in the resulting properties are explained in terms of the developed crystalline phases and microstructure. Keywords: clay based ceramics, shaping, sintering, properties.

Foram utilizados quatro diferentes métodos de conformação e temperaturas de sinterização para entender suas influências nas propriedades finais de um material cerâmico formulado usando argila caulinítica e alumina calcinada. Este material pode ser usado como cerâmica estrutural para diferentes aplicações, e não há relação pré-estabelecida entre o método de conformação e as propriedades sinterizadas finais. Os métodos de conformação utilizados para preparar as amostras foram prensagem uniaxial (processo em batelada que permite a aplicação em amostras secas), extrusão (processo contínuo que requer umidade), colagem (processo que permite moldar produtos cerâmicos complexos) e laminação (processo em batelada que requer umidade

“…Hence, this is an indication of an oxidizing atmosphere during the ring process. The high content of Fe 2 O 3 which averages at 8.468% makes the brick sample suitable for structural related purposes [32]. The high value for the loss on ignition (LOI) at 13.562% is probably due to the presence of carbonates and clays red at low temperature [33].…”

Historical building techniques have been pointed out as a sample of local resistance to colonial technical influence during the early modern period, although this could not be proven by chemical analysis. A clay brick with an attached lime mortar sample was acquired from the former San Francisco Church’s foundation in Intramuros, Manila, Philippines and representative portions (BRK-1, BRK-2, BRK-3, MTR-1, MTR-2, and MTR-3) of the sample were utilized for chemical analysis using various analytical techniques. These are the energy dispersive x-ray fluorescence (EDXRF), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and ultraviolet-visible spectroscopy (UV-Vis) for quantifying organic compounds. The clay brick sample is made of typical sand and clay specifically composed of non-calcareous clay and low refractory fluxes. The brick’s firing temperature was determined to be between 600°C to 800°C in an oxidizing environment. The attached lime mortar sample is probably manufactured using crushed seashells and classified as a hydraulic lime where clayey and sand particles serving as pozzolans. The lime mortar’s microstructure shows that it is well carbonated. Possible organic compounds specifically egg whites (albumen) which may have been added to the lime mortar yielded negative results. Both qualitative tests (Xanthoproteic Test, Ninhydrin Test and Biuret Test) and quantitative assays (Biuret Assay and Bradford Assay) were not able to detect the presence of any proteinaceous compounds in the sample. It has been established based on this material sample that eighteenth century Asian builders working in Manila kept local traditions and rejected European preferences.
