1. The principle of increasing opportunity cost, also known as the low-hanging-fruit principle, says that the least costly options should be exploited first, with more costly options taken up only after the least costly ones have been exhausted. At low prices, only those with low opportunity costs of producing the product would find it worthwhile to offer it for sale. As prices

The effects of different firing temperatures on the stability of perovskite phase, grain size, and dielectric properties were investigated by XRD, TEM, SEM and dielectric measurements. The dielectric ceramics of Pb(Mg1/3Nb2/3)O3-PbTiO3-BaTiO3 system were obtained by chemical coprecipitation in water. The ceramics have higher dielectric constant (7003-9714), lower firing temperature (950-1150℃), quite uniform microstructure with grain size less than 2.5μm, and lower temperature coefficients of capacitance. As a result, it was confirmed that the simple and low cost chemical route used namely coprecipitation in water is a desired meth-od for preparing high property dielectric materials applicable to multilayer capacitors
