| titleOfInvention | Gaseous mixture for surface strengthening of phosphate glasses |
| abstract | The present invention relates to a new composition of a gas forming mixture used in the gas-thermal-chemical treatment of a substrate made of phosphate glass with an effective increase in thermal shock resistance, with a relative weight ratio of 98.0 to 99.3 (wt%). NH 4 Cl; And a gas forming mixture for strengthening the surface of a phosphate glass comprising a compound comprising at least one oxide having a relative weight ratio of 0.7 to 2.0 (wt%) or a compound comprising one of oxides of Groups 3. 4 and 5. Newly proposed, in particular, the oxides of the elements of groups 3. 4 and 5 are Ga 2 O 3 , Fe 2 O 3 , Sb 2 O 3 , CeO 2 , SiO 2 , TiO 2 , Nb 2 O 5 and Ta 2 O 5 Preferably, one of the compounds including the at least one oxide is selected from Al 2 O 3 · 2SiO 2 2H 2 O or Al 2 O 3 · B 2 O 3 . When the gas-forming mixture for surface hardening of the phosphate glass according to the present invention is used as a sample for gas-thermal-chemical treatment for the surface hardening of a substrate made of phosphate glass, the surface by the ammonium chloride alone sample known as an existing optimal sample Compared to treatment, under thermo-mechanical load An effect is created which shows a result of a significant improvement in surface strength. |
