AB  - The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, Ti02 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes in a planetary ball mill. The powders obtained were pressed under different pressures and the results were fitted with a phenomenological compacting equation. Isothermal sintering was performed in air for 120 minutes at four different temperatures. Structural characterization of ZnO-TiOrMgb system' after milling and sintering was performed at room temperature using XRPD measurements. DTA measurements showed different activation energies for pure and doped ZnO-Ti02 systems. The main conclusions are that doped zinc titanate samples achieve higher densities after sintering and that addition of MgO stabilizes the crystal structure of zinc titanate.

AB  - U ovom radu su ispitivane strukturne promene BaTiO3 tokom mehaničke aktivacije. Kao početni prah, korišćen je BaTiO3 (Aldrich) prah čistoće 99.9%. Mehanička aktivacija ovog praha izvršena je mlevenjem u visokoenergetskom planetarnom mlinu sa kuglama u cirkonijum–oksidnoj posudi zapremine 500 cm3. Prečnik kugli iznosio je 8 mm, dok je odnos kugli i praha bio 20:1. Primenjen je kontinualni režim mlevenja u vremenskim intervalima od 10, 20, 40, 60 i 120 minuta. Nakon toga, uzorci su sinterovani 2 sata u komornoj peći na temperaturi od 1300 °C. Za ispitivanja korišćena je serija sinterovanih i nesinterovanih uzoraka. Uzorci pripremljeni na ovaj način proučavani su Raman spektroskopijom.
