Resumen

Milling of BaTiO₃ + 3 wt% ZrO₂ was carried out in an attritor and a planetary mill during different times. When milled in air, BaTiO₃ decomposes into BaCO₃ + TiO₂ and a solid solution between TiO₂ and ZrO₂ is formed. The CO₂ required to form BaCO₃ is taken from the air. However, when a planetary mill with a degased and sealed container is used, the formation of a solid solution between BaTiO₃ and ZrO₂ occurs. In case of the system BaTiO₃ + 3 wt % Y₂O ₃ the solid solution was formed by milling in a shaker mill (SPEX) in air. Annealing the milled mixture at 1000 °C produces YBa ₃Ti₂O_8.5. This suggests that the solid solution of Y₂O₃ and BaTiO₃ formed by mechanical alloying is oversaturated.
