How It Compares
Within the lead-free piezoelectrics class.
While BaTiO3 remains the most widely studied benchmark for piezoelectric performance, Ba2CrNbO6 offers a distinct chemical composition that avoids the environmental concerns associated with lead-based systems. Unlike the simple perovskite structures of NaNbO3 or KTaO3, this compound features a double perovskite lattice, which provides additional degrees of freedom for tuning electronic and electromechanical responses through cation ordering.
