Stabilization of isopropanol dispersions of nanosized powders of yttrium oxide-stabilized zirconium dioxide

摘要

The properties of dispersions of nanosized powders of yttrium oxide-stabilized cubic zirconium dioxide (YSZ) are studied. The sizes of YSZ aggregates are determined under different conditions. Dispersants for dispersions of YSZ nanosized powders in isopropanol are obtained through partial esterification of poly(acrylic acid) with triethyl orthoformate. The composition and structure of the dispersants are optimized.
