Abstract
Dense ceramics are produced from fly ash from REK Bitola, Republic of
Macedonia. Four types of fly ash from electro filters and one from the
collected zone with particles < 0.063 mm were the subject of this research.
Consolidation was achieved by pressing (P= 133 MPa) and sintering (950,
1000, 1050 and 11000C and heating rates of 3 and 100/min). Densification was
realized by liquid phase sintering and solid state reaction where diopside
[Ca(Mg,Al)(Si,Al)2O6] was formed. Ceramics with optimal properties (porosity
2.96?0.5%, bending strength - 47.01?2 MPa, compressive strength - 170 ?5
MPa) was produced at 1100?C using the heating rate of 10?C/min.
