Zirconium alloy Wikipedia

Zirconium alloys are solid solutions of zirconium or other metals, a common subgroup having the trade mark has very low absorption crosssection of thermal neutrons, high hardness, ductility and corrosion of the main uses of zirconium alloys is in nuclear technology, as cladding of fuel rods in nuclear reactors, especially water reactors.

Zirconium and Hafnium Machining

Because of the reactivity of zirconium and hafnium to most gases at welding temperatures, welding without proper shielding will allow the absorption of oxygen, hydrogen, and nitrogen from the atmosphere and thus embrittle the weld. Zirconium and hafnium are most commonly welded by the gas tungsten arc welding (GTAW) technique.

Hafnium | Hf PubChem

The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavymineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.
