Original Abstract

The influence of microstructure on the resulting physico-mechanical and refractory properties of refractory forsterite–spinel ceramics was investigated in this paper. The raw materials were milled, mixed into four different raw material mixtures and sintered for two hours at 1550°C. The microstructure of the samples was examined by scanning electron microscopy and X-ray diffraction analysis was used to determine the mineralogical composition of the sintered samples. Physico-mechanical properties such as porosity, water absorption, bulk density, and modulus of rupture were also determined. Thermomechanical characteristics were assessed by the determination of refractoriness, refractoriness under load, thermal shock resistance and corrosion resistance to various metals. The results showed that a higher amount of spinel leads to improved microstructure, thermal shock resistance and that all mixtures have high corrosion resistance to all tested materials.
