The dependence of Tc of the superconducting ceramics SrxLa2-xCuO4 was measured on the sintering conditions, temperature and time, on the cooling rate after annealing and on the depth from the initial surface of the sample. The sintering temperature 1050C was better than 1000C and the sintering for five hours was the best one. There was no difference between the superconductivity of the initial surface and of the inside of the sample.
