Influence of Bi2O3 on sintering and crystallization of cordierite ceramics
Abstract
Uticaj Bi2O3 kao funkcionalnog dodatka na proces dobijanja kordijerita, 2MgO-2Al2O3-5SiO2 (MAS) proučavan je sinterovanjem sistema MgO/Bi2O3 (sinterovano na 820 i 1100°S), Al2O3/Bi2O3 i SiO2/Bi2O3 (sinterovano na 1100°S) pri čemu je sastav bio 80% oksida i 20% Bi2O3. Efekti sinterovanja, sastav i morfologija praćeni su rendgenostrukturnom difrakcijom, skenirajućom elektronskom mikroskopijom i EDS analizom. Ustanovljeno je da pored tečne faze Bi2O3 pravi intermedijarna metastabilna jedinjenja sa MgO i Al2O3. Takođe je izvršeno sinterovanje MAS keramike sa 10% Bi2O3 na 1000, 1100 i 1200°S.
The influence of Bi2O3 on the process of cordierite ceramics preparation, 2MgO-2Al2O3-5SiO2 (MAS) was investigated. The following binary systems were used for the presented research: MgO/Bi2O3 (sintered at 820ºC and 1100ºC), Al2O3/Bi2O3 and SiO2/Bi2O3 (sintered at 1100ºC). The composition of these systems consisted of 80% of oxide and 20% Bi2O3. The effects of sintering, composition and morphology were investigated by X-ray diffraction, scanning electron microscopy and EDS analysis. It has been found that Bi2O3, besides a liquid phase, forms intermediary unstable compounds with MgO and Al2O3. MAS ceramics were sintered with 10% Bi2O3 at 1000ºC, 1100ºC and 1200ºC.
