Crystallographic characterization of silicon nitride ceramics sintered with Y(2)O(3)-Al(2)O(3) or E(2)O(3)-Al(2)O(3) additions
(ELSEVIER SCI LTD, 2009)
Silicon nitride ceramics were sintered using Y(2)O(3)-Al(2)O(3) or E(2)O(3)-Al(2)O(3) (E(2)O(3) denotes a mixed oxide Of Y(2)O(3) and rare-earth oxides) as sintering additives. The intergranular phases formed after sintering ...
Development and characterization of Al2O3-ZrO2 Composites Using ZrO2(Y2O3)-recycled as raw material
(2018-01-01)
The objective of this work was the development of Al2O3-ZrO2 ceramic composites using recycled-source of ZrO2(Y2O3). Al2O3 powder was mixed with different proportions of ZrO2(Y2O3) arising from pre-sintered blocks used in ...

Processing of different alumina–zirconia composites by slip casting
(Elsevier, 2013-07)
Two Al2O3–ZrO2 mixture preparation routes: classical powder mixing and addition of a Zr (IV) precursor solution to a well dispersed Al2O3 suspension, were used to produce alumina (Al2O3)–zirconia (ZrO2) slip cast composites. ...

Mechanical properties and cytotoxicity of 3Y-TZP bioceramics reinforced with Al(2)O(3) particles
(ELSEVIER SCI LTD, 2009)
The influence of Al(2)O(3) addition and sintering parameters on the mechanical properties and cytotoxicity of tetragonal ZrO(2)-3 mol% Y(2)O(3) ceramics was evaluated. Samples containing 0, 10, 20 and 30 wt.% of Al(2)O(3) ...
