Influence of TiO sub 2 additives on the microstructure of In sub 2 O sub 3 ceramics

Titania additives favor densification and hinder grain growth in indium oxide ceramics. The influence of TiO sub 2 has been investigated, using specimens made by stacking two layers against each other, one of In sub 2 O sub 3 and the other of (TiO sub 2 ) sub x -(In sub 2 O sub 3 ) sub 1-x . After s...

Description
Summary:Titania additives favor densification and hinder grain growth in indium oxide ceramics. The influence of TiO sub 2 has been investigated, using specimens made by stacking two layers against each other, one of In sub 2 O sub 3 and the other of (TiO sub 2 ) sub x -(In sub 2 O sub 3 ) sub 1-x . After sintering, the sharp interface is replaced by a diffuse one, with a graded concentration of TiO sub 2 . Both porosity and grain size decrease when the TiO sub 2 content increases.
