BaTi5O11 was synthesized using a co-precipitation technique and characterized through XRD, SEM, and EDX. The desired structure was achieved through calcination at 900 degrees C, with further characterization done through TGA, FT-IR, and Raman studies. Particle size was found to be between 80 and 120 nm, with an average crystallite size of 68.1 nm.
BaTi5O11 has been widely researched due to its unique microwave properties. Conventionally, it is challenging to obtain this compound as a single phase. The BaTi5O11 was synthesized via a co-precipitation technique using an aqueous solution of titanium(IV)(triethanolaminato) isopropoxide, barium nitrate and ammonia as precursors, which are stable in aqueous media. The phase evolution, purity, and structure were identified by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy analysis. The desired BaTi5O11 structure was obtained by calcination at 900 degrees C. Furthermore, the structure was characterized by TGA, FT-IR and Raman studies. The study showed that the particles were between 80 and 120 nm in size and the average crystallite size was determined from the Scherrer formula as 68.1 nm at 900 degrees C.
