Basic Information
Scope
Scope: This document specifies the technical requirements, quality assurance, marking, packaging, transportation, and storage for ceramic targets made from high-purity yttrium oxide partially stabilized zirconia (ZrO2(HfO2)-7~8 wt. %Y2O3) raw materials synthesized by chemical co-precipitation and electrofusion methods. This document applies to 8YSZ ceramic targets used in electron beam physical vapor deposition (PVD). Main technical content: Table 18 shows the chemical composition and impurity content of 8YSZ ceramic targets.
