beryllium oxide hydrofluoride

Molten salt reactor - WikiVisually

Oxide and sulfur contamination in the salt mixtures were removed using gas sparging of HF – H 2 mixture, with the salt heated to 600 °C. (p8) Structural metal contamination in the salt mixtures were removed using hydrogen gas sparging, at 700 °C. (p26) Solid ammonium hydrofluoride was proposed as a safer alternative for oxide removal.

US7722779B2 - Method and etchant for removing glass ...

An etchant for and method of removing a glass coating on a metallic wire is provided. The etchant comprises an acid solution having metal ions contained therein. The metal ions prevent the acid solution from pitting or damaging the metallic wire, while allowing the acid solution to effectively etch and remove the glass coating. In one embodiment, a fluorine-based acid solution can be used.

Beryllium - Wikipedia

Beryllium oxide is also being studied for use in increasing the thermal conductivity of uranium dioxide nuclear fuel pellets. Beryllium compounds were used in fluorescent lighting tubes, but this use was discontinued because of the disease berylliosis which developed …

A Medley of Potpourri: Molten salt reactor

Jul 22, 2018· A molten salt reactor (MSR) is a class of generation IV nuclear fission reactor in which the primary nuclear reactor coolant, or even the fuel itself, is a molten salt mixture. MSRs can run at higher temperatures than water-cooled reactors for a higher thermodynamic efficiency, while staying at low vapour pressure. The nuclear fuel may be solid or dissolved in the coolant.

Ammonium bifluoride - Howling Pixel

Beryllium oxide. Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is a notable electrical insulator with a higher thermal conductivity than any other non-metal except diamond, and exceeds that of most metals. As an amorphous solid, beryllium oxide is white.
