Thermal diffusivity of sintered 12CaO x 7Al(2)O(3)
(Springer Heidelberg, Heidelberg, 2008)
The thermal diffusivity and free carrier diffusion coefficient of 12CaO x 7 Al2O3 ( C12A7) sintered for different times in air or hydrogen followed by treatment with UV light were determined from photoacoustic phase and ...
Ispitivanje sinterovane cink-kalaj-oksidne keramike fotoakustičnom spektroskopijom / Photoacoustic spectroscopy investigation of sintered zinc-tin-oxide ceramics
(Savez hemijskih inženjera, Beograd, 2007)
Prahovi ZnO i SnO2 pomešani u molarnom odnosu 2:1 mehanički su aktivirani u planetarnim mlinu sa kuglama u intervalu od 10 do 160 minuta. Dobijene smeše presovane su i izotermski sinterovane na 1300 °C, dva sata. Uzorci ...
Investigation of zinc stannate synthesis using photoacoustic spectroscopy
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered ...
