Scope

This document describes the quantitative analysis method for residual Y2O3 in yttrium-stabilized zirconia (YSZ) powder. This document is applicable to the quantitative analysis of residual Y2O3 in YSZ powder, with an analysis range of a mass percentage of greater than or equal to 0.00075%. The scope of application of this document is as follows: a) This document is suitable for YSZ powders or blocks prepared by the following methods: co-precipitation method, sol-gel method, and solid-phase synthesis method. Plasma spraying (PS) and electron beam physical vapor deposition (EB-PVD) methods are also applicable to YSZ coatings. Generally, the experimental error of such samples does not exceed 10%. b) Due to the large grain size, high hardness, and difficulty in crushing, this document is not suitable for YSZ blocks prepared by the following methods: arc melting and high-pressure sintering.
