METHOD FOR TREATMENT OF SURFACE OF OXIDE GLASS WITH FLUORINATING AGENT |
摘要 |
To provide a novel fluorination treatment method whereby the surface of oxide glass can be treated for fluorination at low cost and with excellent adhesiveness. A method for treating the surface of oxide glass, which comprises contacting the surface of oxide glass with a gas of a fluorinating agent or a mixed gas having a fluorinating agent diluted with an inert gas, wherein the fluorinating agent is an elemental fluorine, or a fluorine compound capable of cleaving a bond between an oxygen atom and a metal atom in the framework of the oxide glass and forming a bond between a fluorine atom and the metal atom; and the concentration of hydrogen fluoride at the surface of oxide glass with which the fluorinating agent is in contact, is controlled to be at most 1 mol%. |
