Also known as hafnium dioxide or hafnia, this colourless solid is one of the most common and stable compounds of hafnium. It is an electrical insulator with a band gap of 5.3~5.7 eV. Hafnium dioxide is an intermediate in some processes that … See more Hafnia typically adopts the same structure as zirconia (ZrO2). Unlike TiO2, which features six-coordinate Ti in all phases, zirconia and hafnia consist of seven-coordinate metal centres. A variety of other crystalline … See more Hafnia is used in optical coatings, and as a high-κ dielectric in DRAM capacitors and in advanced metal–oxide–semiconductor devices. Hafnium-based oxides were introduced by Intel in 2007 as a replacement for silicon oxide as a gate insulator in See more

WebOct 1, 2009 · The ICOM is a metal package that consists of a single quartz crystal and associated circuitry that generates a pure sine wave at the desired frequency. The precise physical dimensions of the quartz crystal determine its frequency. When a voltage is applied across the quartz crystal, the crystal will flex at its resonant frequency.

WebAmmonium bifluoride is a component of some etchants. It attacks silica component of glass: SiO 2 + 4 [NH4] [HF2] → SiF 4 + 4 [NH 4 ]F + 2 H 2 O. Potassium bifluoride is a related more commonly used etchant. Ammonium bifluoride has been considered as an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid.
