Titrimetric determination of zirconium

Zirconium was discovered by the German chemist Martin H. Klaproth in 1789. The principal ore of zirconium is zircon, which is widely distributed in nature as beach sands, particularly in Australia and India. Zirconium is the nineteenth most abundant element in the earth's crust (at approximately 0.03%).

WebElements Periodic Table » Hafnium » historical information

Interesting Hafnium Facts: Hafnium wasn't discovered until 1923 by Dirk Coster and Georg von Hevesy. The pair discovered hafnium by using x-ray spectroscopy on sample of zirconium ore. At the time of its discovery, hafnium was one of the two non-radioactive elements that had been predicted but had not yet been discovered.

Zirconium | chemical element | Britannica

Zirconium is relatively abundant in Earth's crust, but not in concentrated deposits, and is characteristically observed in S-type stars. The mineral zircon, which is generally found in alluvial deposits in stream beds, ocean beaches, or old lake beds, is the only commercial source of zirconium.

Hafnium was discovered by Dirk Coster, a Danish chemist, and George Charles de Hevesy, a Hungarian chemist, in 1923. They used a method known as X-ray spectroscopy to study the arrangement of the outer electrons of atoms in samples of zirconium ore. The electron structure of hafnium had been predicted by Niels Bohr and Coster and Hevesy found a pattern that matched.

Zirconium oxide is to be found in ultra-strong ceramics that are stronger and sharper even than toughened steel and are used for knives, scissors and golf irons. Production of pure zirconium oxide is almost 25 000 tons per year, and it also goes into various chemicals that end up as cosmetics, antiperspirants, food packaging, and even fake gems.

Zirconium and Hafnium Statistics and Information

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 heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.
