Abstract

Nickel silicide nanocrystal containing Si-Ni-C-N multiphase ceramics were synthesized by bulk pyrolysis of the mixture of polysilazane (PSZ) and nickelocene (NiCp₂) at high temperature. The pyrolysis behavior of the precursors was investigated by TGA/DSC-Mass Spectrometry. The yield of the ceramic containing NiCp₂ precursor was increased by 8-10% compared to pure PSZ. Nickel silicide nanocrystal containing ceramics were characterized by transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and Raman spectroscopy. The NiCp₂ in polymeric precursors induced the formation of α-Si₃N₄, SiC, graphitic carbon, and Ni₂Si at 1100 C. Nickel silicide nanocrystals containing ceramics exhibited soft magnetism with ultralow hysteresis loss offering a convenient cost effective approach for the preparation of tunable transition metal-containing ceramics using a commercial inexpensive polymeric precursor of NiCp₂.
