Synthesis of barium titanate using microwave heating method at different heating time

Barium titanate (BaTiO3) is a ceramic material with significant applications in electronic, optical, and energy-related fields due to its exceptional dielectric constant,
ferroelectric, and piezoelectric properties. But conventional synthesis techniques often produce low-purity materials at high temperatures and with hazardous chemicals.
Microwave-aided synthesis has surfaced as a potentially advantageous substitute, providing enhanced purity, quicker reaction rates, and larger yields. The primary objectives of this work are to synthesise and characterise barium titanate by means of microwave heating. The goals include figuring out the microstructure, dielectric constant, and crystallographic phases of BaTiO3, as well as investigating how radiation duration affects this formation. Titanium oxide and barium carbonate were combined, ground, dried, and microwave-heated. After that, the material was sintered and packed into pallets. The synthesised materials were analysed using characterization methods including as optical microscopy (OM), X-ray diffraction (XRD), density and porosity studies, and dielectric testing. The results demonstrate that microwave heating is a sustainable and effective method for manufacturing high-quality barium titanate, which has potential uses across numerous sectors. This advances the development of synthetic procedures for complicated oxide materials.
