摘要： Proposed is a zirconium crucible used for melting an analytical sample in the pretreatment of the analytical sample, wherein the purity of the zirconium crucible is 99.99wt% or higher. In light of the recent analytical technology demanded of fast and accurate measurement of high purity materials, the present invention provides a zirconium crucible for melting an analytical sample, a method of preparing such analytical sample, and a method of analysis that enables the analysis of high purity materials by inhibiting the inclusion of impurities from the crucible regardless of difference in the analysts and their skill.
