METHOD FOR PRODUCING GLASS SHEET AND GLASS SHEET |
| 摘要 |
The glass sheet production method of the present invention is a method for producing a surface-modified glass sheet. This method includes a gas contact step of bringing hydrogen fluoride (HF) gas and hydrogen chloride (Cl) gas into contact with at least one principal surface of a glass sheet having a temperature in a range of 450° C. to 630° C. A gas containing the hydrogen fluoride (HF) gas is used in the gas contact step, and in the gas containing the hydrogen fluoride (HF) gas, a volume ratio of water vapor to the hydrogen fluoride (HF) gas (volume of water vapor/volume of HF gas) is less than 8. |

1. A method for producing a surface-modified glass sheet, comprising a gas contact step of bringing hydrogen fluoride (HF) gas and hydrogen chloride (HCl) gas into contact with at least one principal surface of a glass sheet having a temperature in a range of 450° C. to 630° C., wherein
a gas containing the hydrogen fluoride (HF) gas is used in the gas contact step, and in the gas containing the hydrogen fluoride (HF) gas, a volume ratio of water vapor to the hydrogen fluoride (HF) gas (volume of water vapor/volume of HF gas) is less than 8. |
