Lutetium–hafnium dating

17 hours ago   Lutetium–hafnium dating is a geochronological dating method utilizing the radioactive decay system of lutetium–176 to hafnium–176. With a commonly accepted half life of 37.1 billion years, the long living Lu–Hf decay pair survives through geological time scales, thus is useful in geological studies. Due to chemical properties of the two elements, namely their

Hafnium, Hf

Hafnium, Hf. Hafnium is a chemical element that has the symbol Hf and atomic number 72. A lustrous, silvery gray tetravalent transition metal, hafnium resembles zirconium chemically and it is found in zirconium minerals. Hafnium is used in tungsten alloys in filaments and electrodes, in integrated circuits as a gate insulator for transistors

2022 5 20   In this work, we investigated the ferroelectric properties of Hf 0.5 Zr 0.5 O 2 HZO Metal Ferroelectric Metal MFM capacitors on various refractory electrodes, including TiN, TaN, W, and Mo. By comparing different electrodes and annealing temperature, we found that the MFM capacitors with TiN and W electrodes showed both higher remanent polarization 2P r and

Hafnium Hf Z = 72

2022 4 12   Abstract. Hafnium is always found associated with zirconium, because of their similar geochemical behavior. Zircon ZrSiO 4 is the most common naturally occurring zirconium and hafnium bearing mineral. Most zircon forms as a product of primary crystallization in igneous rocks. Download chapter .
