Abstract [en]

Based on a thermal stability study, the sinterability of the oxynitride LaTiO2N was investigated by spark plasma sintering (SPS). The results show that LaTiO2N is thermodynamically unstable above ca. 400 degrees C in air and ca. 800 degrees C in argon. While it appears impossible to completely avoid decomposition during sintering, LaTiO2N ceramics with relative density of 74-94% and a residual LaTiO2N content of 57-90 wt% were prepared. By manipulating kinetics, a relative density of 94% was achieved at 1350 degrees C under an uniaxially applied pressure of 125 MPa. This density is higher than any other counterparts prepared by conventional sintering so far. SPS appears a feasible tool for manipulating the sintering kinetics. It enables the preparation of almost dense LaTiO2N bulks with adequate purity.
