Özet

The binary compounds (C(3)A: Ca3Al2O6, C(12)A(7): Ca12Al14O33, CA: CaAl2O4, CA(2): CaAl4O7 and CA(6): CaAl12O19) of CaO-Al2O3 system have been synthesized as high compound-purity ceramic powders by using the Combustion Synthesis (CS) method. Materials characterization of the above-mentioned phases were performed by powder XRD, FTIR, SEM and EDXS. It has hereby been shown that by using this synthesis procedure it would be possible to manufacture high-purity ceramic powders of CA, CA(2), and C(12)A(7) at 850 degrees C, and of C(3)A and CA(6) at 1050 degrees C in a stagnant air atmosphere.
