dc.description.abstract | The present study aims to evaluate the potential use of bagasse ash from sugar cane
(CBC) as a flux, replacing phyllite and/or feldspar in standard industrial mass
production of enameled porcelain, verifying the possibility of the CBC contribute to
the overall reduction of the coefficient of thermal expansion of the ceramic mass. To
this end, as a result of the research, we characterized the raw material components
of the standard mass (clay, phyllite, kaolin, feldspar, quartz and talc) and the residue
of BCC, by testing by XRF, XRD, AG, DTA and ATG. Specimens (CDP) were
manufactured in the dimensions of 100 mm x 50 mm x 8 mm in uniaxial matrix under
compaction pressure of 33 MPa, assembled in batches of 3 units subsequently
sintered at temperatures of 1150°C to 1210°C by varying the Rating Scale at 10°C,
heating and cooling ramp of 50°C/min and 25°C/min, with levels of 1 min, 3 min, 5
min, 8 min, 10 min, 15 min, 30 min and 60 min. analyzing the results of the physical
properties of water absorption (WA), linear firing shrinkage (LFS), dilatometric
analysis (DTA), flexural strain (SFT) and SEM of the sintered bodies in order to verify
the adequacy of CDP to ISO 13006, ISO 10545, NBR 13816 standards; NBR 13817
and NBR 13818. The study showed that the formulations that best suit the
requirements of the standards are:. G4 - which was applied in 10% of replacing the
CBC phyllite, sintering temperature 1210 ° C for 10 min and porch, and F3 - with
application of 7.5% of CBC to replace the feldspar in the sintering temperatures of
1190°C, 1200°C and 1210°C for 10 min and porch. These formulations showed
better performance regarding the formation of primary and secondary mullite, with
considerable reduction of cracks and pores, meeting the prerequisites of standards
for glazed porcelain. The results shows that the use of the CBC as a flux in the
preparation of porcelain mass meets standard parameters for the manufacture of the
product, and thereby can reduce environmental impact and the cost of production.
Therefore, it is recommended to use this residue in the ceramics industry, due to its
industrial, commercial and collaborative viability for sustainability. | |
