The method of zone melting has permitted the preparation of zirconium containing 8 x 10/sup -6/ iron and 1 x 10/sup -6/ nickel, which corresponds to purification factors of 100 and 20, respectlvely. This high degree of purification is caused by the superposition of the zone melting mechanism and of fusion treatment under vacuum. The stability of the vertical melted zone was considerably improved in the case of zirconium by moving the zone displacement from the top to the bottom. (tr-auth)
