Sintering behaviour of slip-cast Al2O3 - Y-TZP composites
The sintering behaviour of alumina-Y-TZP composites prepared by slip-casting technique were studied. Slip-cast samples containing varying amounts of Y-TZP ranging up to 90 vol% were prepared and evaluated. Sintering studies were carried out at 1450 �C to 1600 �C. Sintered samples were characterized...

| description | The sintering behaviour of alumina-Y-TZP composites prepared by slip-casting technique were studied. Slip-cast samples containing varying amounts of Y-TZP ranging up to 90 vol% were prepared and evaluated. Sintering studies were carried out at 1450 �C to 1600 �C. Sintered samples were characterized where appropriate to determine phases present, grain sizes, bulk density and mechanical properties. Good correlation was obtained between the calculated prepared powder density and experimental results. The sintered bulk density of the composites was observed to increase with increasing Y-TZP content and sintering temperature up to 1550 �C. Maximum hardness values (>14 GPa) were obtained for all samples containing >60 vol% Y-TZP and when sintered at 1550 �C. It has been found that the additions of up to 50 vol% Y-TZP was effective in suppressing Al2O3 grain growth. |
