Ceramics microstructure was designed using waste flay ash (REK Bitola, Macedonia) and clay. The raw materials were characterized from chemical, mineralogical and thermal aspect. The ceramics was designed using the granulation less than 0.063 mm. The clay content varied from 10 to 90 wt.%. The consolidation of the compacts was realized at pressure of 45 MPa and sintering at different temperatures (900, 1000, 1500 and 1100 oC/1h, heating rate of 10oC/min).
The designed microstructure of the composite with composition 60wt% clay and 40wt% fly ash sintered at 1100oC/1h was found as optimal regarding to its properties: density- 2.089g/cm2; water absorption- 7.02%, bending strength – 50.47 MPa and E-modulus - 25,35GPa. Technical coefficient of thermal expansion was α20-600=7.03x10-6/oC.
