| Abstract |
| Polycrystalline yttrium aluminium iron garnets with varying AIsubstitution
(0 ,; x ,; 0.9) have been prepared in the pellet form.
Sintering studies have been carried out both in ball-milled and coprecipitated
powders. It is observed that higher sintering temperature
is needed with increasing Al-substitution in YIG to obtain density
greater than 98% of the theoretical density. Process conditions
to achieve uniform grain size and high density are discussed. Some
hot pressed samples have also been prepared to obtain fine microstructure. |
