Production method for thermochromatic glass in which use is made of a low-temperature metal-vapour-deposition process, and thermochromatic glass obtained thereby

摘要

The present invention relates to a production method for thermochromatic glass in which use is made of a low-temperature metal vapor deposition process, and to thermochromatic glass obtained thereby. More specifically, the invention relates to: a production method for thermochromatic glass in which a low-temperature metal-vapor-deposition process is used in order to effect the vapor deposition of a metal for forming a thermochromatic metal oxide and then subsequently a heat treatment is carried out, such that the processing efficiency is high and the reliability of the thermochromatic characteristics of the glass produced by the method is outstanding; and to thermochromatic glass obtained by means of the method.

1. A method of producing a thermochromatic glass, comprising:
depositing a metal for forming a thermochromatic metal oxide on a glass substrate; and performing post-heat treatment of the glass substrate to form a crystal phase of the thermochromatic metal oxide through oxidation of the deposited metal, wherein the post-heat treatment is performed at a temperature of 460° C. to 480° C., and wherein the post-heat treatment is performed for 360 to 600 seconds; wherein the metal for forming a thermochromatic metal oxide comprises vanadium (V); and wherein the crystal phase of the thermochromatic metal oxide comprises vanadium dioxide (VO2).
