Özet

Zirconium diboride (ZrB ₂)-zirconium dioxide (ZrO ₂) ceramic powders were prepared by comparing two different boron sources as boron oxide (B ₂O ₃) and elemental boron (B). The production method was high-energy ball milling and subsequent annealing of powder blends containing stoichiometric amounts of ZrO ₂, B ₂O ₃/B powders in the presence of graphite as a reductant. The effects of milling duration (0, 2 and 6 h), annealing duration (6 and 12 h) and annealing temperature (1200-1400°C) on the formation and microstructure of ceramic powders were investigated. Phase, thermal and microstructural characterizations of the milled and annealed powders were performed by X-ray diffractometer (XRD), differential scanning calorimeter (DSC) and transmission electron microscope (TEM). The formation of ZrB ₂ starts after milling for 2 h and annealing at 1300°C if B ₂O ₃ is used as boron source and after milling for 2 h and annealing at 1200°C if B is used as boron source.
