Bismuth oxide based ceramics with improved electrical and mechanical properties

Coprecipitated compositions of (1-x)Bi sub 2 O sub 3 -xEr sub 2 O sub 3 containing < or = 25 mol% Er sub 2 O sub 3 show a slow transition on heating at 900 K from a cubic to a hexagonal phase, which is stable up to 1000 K. Compositions containing 30 mol% Er sub 2 O sub 3 do not show any such chan...

Description
Summary:Coprecipitated compositions of (1-x)Bi sub 2 O sub 3 -xEr sub 2 O sub 3 containing < or = 25 mol% Er sub 2 O sub 3 show a slow transition on heating at 900 K from a cubic to a hexagonal phase, which is stable up to 1000 K. Compositions containing 30 mol% Er sub 2 O sub 3 do not show any such changes.
