The present paper aims to synthesise a composite powder consisting of zirconia toughened alumina (ZTA) and calcium fluoride (CaF 2 ) together followed by their morphological study and characterization. Yttria-stabilized zirconia toughened alumina added with CaF 2 was fabricated in the laboratory with the aid of co-precipitation method. The morphological and elemental studies are carried out by means of field emission scanning electron microscopy (FESEM) coupled with energy dispersive X-ray analysis (EDS). Presence of different phases are investigated using the X-ray diffraction (XRD) analysis. The temperature at which the powder decomposes are obtained by differential thermal analysis/thermo gravimetric analysis (DTA/TGA).
