| Description |
Different low thermal expansion ceramics of Ca1-xSrxZr4(PO4)6 system with x = 0, 0.25, 0.5 and 0.75 were synthesized by the solid state reaction method. After several heat treatments finished products were obtained at 1300¢XC. These were characterized for phase purity by X-ray Diffractometry and IR Spectroscopy. Densification parameters of the compositions with 3 and 5 wt% ZnO added as sintering aids were studied at 1100¢X, 1200¢X and 1300¢XC under soaking periods of 2-6 h. The corresponding effects on the physical, thermal and mechanical properties were observed. A maximum of 98% of theoretical density was obtained and flexural strength as high as 70 MPa was achieved. Thermal expansion varied from ¡V0.47 to 2.65 ¡Ñ 10¡V6/¢XC with increase in Sr content. The results are discussed in the light of the microstructures.
