Calcium and hafnium co-doped barium titanate could be used as a replacement for lead zirconate titanate, which is a lead-based ferroelectric material. Solid state reaction accompanied by the usual sintering technique is the classical ceramic-processing method, which demands a lot of time and effort. The present work aims to make the process a lot easier and quicker by employing a modified sol-gel combustion technique to synthesize polycrystalline Ba0.85Ca0.15Ti(1-x)HfxO3 (x=0.00, 0.05, 0.10,doi:10.21203/rs.3.rs-243264/v1 fatcat:rtchq7abrjhqfj2lir4dwifuke
