The fabrication of ceramic materials implies dealing with a great number of processing variables with clear interaction, which prevents straightforward optimization of the processes. In this paper, we report the optimization process applied to improve the properties of LFZ-textured Bi-2212 superconducting thin rods. In this process, based on Simplex optimization methods, four growth and four annealing parameters were taken as control variables to obtain high critical currents and short processing times. As a result, the critical current values increased by a factor of 3 after only 30 trials.
