Influence of treatment with sulfuric acid on the angularity of a zirconia system
Abstract
Small-angle X-ray scattering (SAXS) measurements have been used to determine the influence of sulfation on the morphology of zirconia particles. Two samples were investigated: a zirconium oxide powder before (sample A) and after (sample B) a sulfation treatment with H2SO4. The decrease of about one order of magnitude in the angularity value for sample B provided quantitative proof of transmission electronic microscopy (TEM) evidence.
