Surface chemical treatment for liquid gallium or gallium alloy mirrors |
摘要 |
The invention relates to a method of treating a liquid gallium or gallium alloy surface for prolonged use as a liquid mirror. The method of the invention comprises the steps of (a) contacting the surface of liquid gallium or gallium alloy with an aqueous solution of a halogenic acid to cause dissolution of any gallium oxide present on the surface, thereby obtaining an oxide-free liquid gallium or gallium alloy surface covered with a layer of the acid solution; (b) adding to the acid solution an aqueous solution of a surfactant present in an amount to form a single bimolecular layer of surfactant at an interface between the liquid gallium or gallium alloy and water; and (c) allowing a uniform passivating oxide layer to gradually form on the oxide-free liquid gallium or gallium alloy surface, the passivating oxide layer having surface irregularities smaller than 40 nm.
