Transparent ceramics of yttrium-aluminum garnet (Y₃Al₅O₁₂) from nanocrystalline powders obtained by co-precipitation
Nanosized powders of yttrium-aluminum garnet Y₃Al₅O₁₂, (YAG) have been obtained by chemical co-precipitation. The effect of the powder structure and morphology on the compactibility and sinterability has been studied. The optimal combination of these properties has been found in the YAG powder havin...
