ST0514 Hafnium Oxide with Calcium Oxide Sputtering Target, HfO2/CaO

Hafnium Oxide with Calcium Oxide Sputtering Target Description

Hafnium is a lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1923, by Coster and Hevesy, making it the last stable element to be discovered. Hafnium is named after Hafnia, the Latin name for Copenhagen, where it was discovered.

Calcium is a chemical element that originated from the Latin ‘calx’ meaning lime. It was first mentioned in 1808 and observed by H. Davy. The isolation was later accomplished and announced by H. Davy. “Ca” is the canonical chemical symbol of calcium. Its atomic number in the periodic table of elements is 20 with location at Period 4 and Group 2, belonging to the s-block. The relative atomic mass of calcium is 40.078(4) Dalton, the number in the brackets indicating the uncertainty.
