Electrical properties of mechanochemically activated cordierite ceramics
Abstract
Three-component oxide mixtures were prepared containing MgO, Al 2 O 3 and SiO 2 in a 2 : 2 : 5 ratio with addition of 10% Bi 2 O 3. The mixtures were mechanically activated in a range from 5 to 240 min in a mill with ceramic balls, and sintered in the range 1173–1573 K. In order to determine the structure transformations, sintered products were analyzed by the XRD method. The goal of the research was to find the possible correlation between process parameters and functional properties of the cordierite-based ceramic materials. Quantitative measures of the functional sample properties, capacity (C c ) and electrical resistance (R ρ), as well as of dielectric loss (tgδ) were used. The results obtained prove that there is a correlation between mechanical activation and properties of cordierite ceramics.
