Sažetak
Important ceramics materials are prepared from aluminosilicate based precursors using novel methods, offering at the same time a better control over many important properties. Forsterite due to its good refractoriness with melting point at 1890oC, excellent electrical insulation properties even at high temperatures, low dielectric permittivity, thermal expansion and chemical stability, is a material of interest to engineers and designers especially as an active medium for tunable laser and is also material of interest to the SOFC (Solid oxide fuel cells) manufacturers. The aim of this study is to investigate the synthesis of crystalline forsterite using different zeolite precursors that are previously activated by ball milling. Synthetic forsterite is synthesised from different zeolite precursors and MgO combining high-energy ball milling and thermal treatment of the mixture under determined conditions of the time and temperature for each operation. In this research the solid-state phase transformations are observed at temperatures below 1000oC. The obtained product is characterised using different spectroscopy techniques in comparison with surface analysis method and X-ray diffraction.
