On Mullite Crystallization in Ceramic Composites

The particulars of mullite crystallization during the synthesis of the ceramic composite material ‘mullite – zirconium oxide,’ obtained from a two-phase gel by co-precipitation combined with sol-gel synthesis, were studied. Powders of the ceramic composite material ‘mullite – ZrO2‘ were obtained. They were heat treated at 1150 and 1350°C. Samples of the ceramic composite ‘mullite – zirconium oxide’ were made from the obtained powders by semi-dry pressing. The microstructure and phase composition of the ceramic were studied.
