Abstract

U okviru ove doktorske disertacije proučene su dve metode dobijanjaAl2O3-Y3Al5O12 kompozita i ispitan je uticaj mikrostrukture na osobine dobijenekompozitne keramike. Ispitivanja su obuhvatila metode sinteze Itrijum (Yttrium)Aluminijum Garneta (YAG) hemijske formule Y3Al5O12 kao i njegove inkorporacije ualumina (Al2O3) matricu u cilju dobijanja kako poroznog tako i gustog kompozita sapoboljšanim osobinama u odnosu na čistu aluminu...

Within this doctoral dissertation, two methods of obtaining Al2O3-Y3Al5O12composite were studied as well as the effects of the microstructure on the properties ofthe obtained composite ceramics. The study included the methods of synthesis ofYttrium Aluminium Garnet (YAG) with chemical formula Y3Al5O12 as well as itsincorporation into alumina (Al2O3) matrix in order to obtain both porous and densecomposites with improved properties relatively to pure alumina...
