Method for making minor dopant additions to porous ceramics

An infiltration technique for doping porous ceramic bodies before sintering is evaluated for calcia additions to yttria stabilised zirconia. The method involves impregnating the porous body with a solution containing the required dopant nitrate, followed by drying and sintering to decompose the nitr...

Summary:An infiltration technique for doping porous ceramic bodies before sintering is evaluated for calcia additions to yttria stabilised zirconia. The method involves impregnating the porous body with a solution containing the required dopant nitrate, followed by drying and sintering to decompose the nitrate and densify the ceramic body. The resulting dopant distributions show equivalent homogeneity to the popular ball milling approach for dopant contents below 3 mol.-%CaO, while giving a product with a higher relative density.
