The Unidad de Fomento (UF) is a unit of account used in Chile. It is a non-circulating currency; [1] the exchange rate between the UF and the Chilean peso is constantly adjusted for inflation so that the purchasing power of the Unidad de Fomento remains almost constant on a daily basis during low inflation. It was created on 20 January 1967 ...
A common impurity is UO 2 F 2. UF4 is susceptible to hydrolysis as well. [1] UF 4 is formed by the reaction of UF 6 with hydrogen gas in a vertical tube-type reactor. The bulk density of UF 4 varies from about 2.0 g/cm 3 to about 4.5 g/cm 3 depending on the production process and the properties of the starting uranium compounds.
Uranium pentafluoride is an intermediate in the conversion of uranium tetrafluoride to volatile UF 6: 2 UF 4 + F 2 → 2 UF 5 2 UF 5 + F 2 → 2 UF 6. It can be produced by reduction of the hexafluoride with carbon monoxide at elevated temperatures. [1] 2 UF 6 + CO → 2 UF 5 + COF 2. Other reducing agents have been examined. [2]

The farad (symbol: F) is the unit of electrical capacitance, the ability of a body to store an electrical charge, in the International System of Units (SI), equivalent to 1 coulomb per volt (C/V). [1] It is named after the English physicist Michael Faraday (1791–1867). In SI base units 1 F = 1 kg −1 ⋅m −2 ⋅s 4 ⋅A 2.
A lower molar ratio of formaldehyde decreases the emission of free formaldehyde from UF products. There is a significant decrease in formaldehyde emissions from UF-based particleboard from F/U molar ratio of 2.0 to 1.0. The German standard for UF resins require the F/U molar ratio to be below 1.2. The U.S. NPA standard is an F/U molar ratio ...
When UF 6 is exposed to moist air, it reacts with the water in the air to produce UO 2 F 2 (uranyl fluoride) and HF (hydrogen fluoride) both of which are highly corrosive and toxic. In 2005, 686,500 tonnes of D-UF 6 was housed in 57,122 storage cylinders located near Portsmouth, Ohio; Oak Ridge, Tennessee; and Paducah, Kentucky.
