Large-scale synthesis of YSZ nanopowder by Pechini method

Bulletin of Materials Science, 2014
Yttria-stabilized zirconia nanopowders were synthesized on a relatively large scale using Pechini method. In the present paper, nearly spherical yttria-stabilized zirconia nanopowders with tetragonal structure were synthesized by Pechini process from zirconium oxynitrate hexahydrate, yttrium nitrate, citric acid and ethylene glycol.

Enhancing the Reactivity of Dicalcium Silicate Using Aluminum and Sulfur Ions Co‐Doping

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Belite‐rich cements are a lower‐energy and lower‐CO2 alternative to Portland cements, but the low hydraulic activity of belite remains a major limitation. This study explores the impact of aluminum and sulfur co‐doping on the structure and hydration of synthetic dicalcium silicate (C2S).
