Abstract

See full text

In light of the recent analytical technology demanded of fast and accurate measurement of high purity materials, a zirconium crucible is provided for melting an analytical sample and is capable of inhibiting the inclusion of impurities from the crucible by using a high-purity crucible, improving the durability of high-purity zirconium as an expensive crucible material, and increasing the number of times that the zirconium crucible can be used. With this zirconium crucible used for melting an analytical sample in the pretreatment of the analytical sample, the purity excluding gas components is 3N or higher, and the content of carbon as a gas component is 100 mass ppm or less.
