Abstract

La(Fe, Si)13 magnetocaloric compounds have been synthesized by high energy ball milling (BM) and sintered by Spark Plasma Sintering (SPS), starting either from an already annealed sample or from a non-annealed sample (reactive sintering). It is possible to form the NaZn13 phase directly by reactive sintering at only 1273K. The influence of the annealing temperature has been investigated in details as well as other parameters. The properties of sintered compounds have been compared with those of samples which were only prepared by BM and annealed.
