Chepetsky Mechanical Plant (ChMP JSC), a subsidiary of TVEL Fuel Company in Glazov, Udmurt Republic, started pilot works of recycling the waste, which had been stored at the facility during the years of producing uranium tetrafluoride
. This is Russias first project of recycling tailings dump bottom settings left after uranium conversion.
Thus, the country managed to convert yellow cake to UF4 (Uranium tetrafluoride
) and UF (Uranium hexafluoride), producing 3.5-5 percent uranium.
"The process of increasing the capacity to produce UF6 (uranium hexafluoride) and UF4 (uranium tetrafluoride
) will begin on Tuesday," Kamalfandi said in an interview with Iran's ISNA news agency.

Then, bare Si removed native oxide by carbon tetrafluoride
(C[F.sub.4]) etching to ensure cavities were symmetrical.

Ten studies investigated the remineralising effect on early enamel caries using silicon tetrafluoride
, fluoride gel, silver diamine fluoride or sodium fluoride.
This Complex was prepared through the reaction of 2-Amino pyridine and titanium tetrafluoride
salt of in acetonitrile.
The fuel used in Leblanc's reactor is the same low-enriched uranium used in light-water or CANDU reactors but in a very different form: a uranium tetrafluoride
salt, which is mixed with other fluoride salts like lithium fluoride, potassium fluoride or zirconium fluoride (Leblanc is understandably cagey about the precise formulation).
The subsequent cleaning of the highly explosive gaseous silicon tetrafluoride
(28SiF4) and its conversion to silane (28SiH4), and subsequently to polycrystalline silicon was pioneering work which took place at the Institute of Chemistry of High-Purity Substances of the Russian Academy of Sciences in Nizhny Novgorod.

"These included tons of uranium liquid wastes, sources, uranium oxides, and uranium tetrafluoride
. Some of these items are still there, but there's no enriched uranium," he said.
