A Rapid Decomposition Method for Analyzing Zirconia

Abstract

A rapid method is presented for the decomposition of zirconia using a suitable combination of (NH4) F + (NH4)2SO4 as fusion agent at about 350°C. The cooled melt (cake) is easily soluble in acidified water in 15-20 minutes. The sample solution may be used for recovery of many components using several analytical methods. During the composition silica is volatilized completely.
