AB  - Ceramics for electronics play an important role in several industrial sectors. The most common way of producing these ceramics is through sintering processes from powders. The powders can be treated by mechanical activation; during this process they are subjected to grinding and the grain size is reduced. Crystal structure is distorted and changed; in some systems, the process leads to chemical reaction and formation of new compound. In this paper we explain the influence of mechanical activation on sintering kinetics in system MgCO3-TiO2. Mechanical activation of the starting powder mixture was performed by milling during different time intervals within 120 min in a planetary ball mill device with ZrO balls and vessels; ball to powder mass ratio was 40:1. Powders were compacted and sintered isothermally at 1100°C for 180 min. X-ray powder diffraction was used for observing the evolution of magnesium-titanate phase during milling. For specimens synthesized in such manner, microwave dielectric properties were measured, namely dielectric loss (tg δ), specific electric resistance (ρ) and relative dielectric permittivity (εr).

AB  - ZnO-SnO2 ceramics were prepared with a traditional powder mixed oxide route by mixing starting powders of ZnO and SnO2 in the molar ratio 2:1 and adding small amounts (0.5; 1.0; and 1.5 molar%) of Bi 2O3. These mixtures were then mechanically activated for 10 minutes in a planetary ball mill, uniaxially pressed and sintered at 1300°C for 2h. The phase composition of the sintered samples was determined with X-ray Diffraction (XRD) analysis and a detailed Rietveld analysis was performed. Room temperature far infrared reflectivity diagrams were obtained using Bruker 113V FTIR spectrometer and fitted with several theoretical models in other to determine parameter values for some structural and optical properties of the obtained material.
