Definitions
- the present invention relates to a tempered glass, a tempered glass plate, and a tempered glass, and particularly, a tempered glass suitable for a glass substrate of a mobile phone, a digital camera, a PDA (portable terminal), a solar cell cover, or a display, particularly a touch panel display.
- the invention relates to a tempered glass plate and a tempered glass.
- the present invention also relates to a tempered glass container, and more particularly to a tempered glass container suitable for a pharmaceutical container.
- Devices such as mobile phones, digital cameras, PDAs, touch panel displays, large televisions, and non-contact power supply are becoming increasingly popular.
- tempered glass tempered by ion exchange treatment or the like is used (see Patent Document 1 and Non-Patent Document 1).
- the ion exchange treatment is usually performed by immersing the strengthening glass in a KNO 3 molten salt at a high temperature (eg, 300 to 500 ° C.). Therefore, when a glass containing a large amount of Li 2 O, Na 2 O, and K 2 O is subjected to ion exchange treatment, when the tempered glass is immersed in the KNO 3 molten salt, or when the tempered glass is taken out, the tempered glass is caused by thermal shock. It becomes easy to break.
- the present invention has been made in view of the above circumstances, and its technical problem is to reduce density and high-temperature viscosity, to hardly deteriorate an ion exchange solution, particularly KNO 3 molten salt, and to have thermal shock resistance.
- the idea is to create a tempered glass and a tempered glass that are excellent in the above.
- the present inventors have reduced the contents of Li 2 O and K 2 O while increasing the contents of Al 2 O 3 and Na 2 O in the glass composition. Accordingly, if B 2 O 3 is introduced and the content of MgO is reduced, the ion exchange performance is not lowered, the density and the high temperature viscosity are lowered, and the ion exchange solution is deteriorated and the thermal shock resistance is improved.
- the present invention is found and proposed as the present invention. That is, the tempered glass of the present invention is a tempered glass having a compressive stress layer on the surface, and the glass composition is SiO 2 50 to 80%, Al 2 O 3 5 to 30%, Li 2 O 0 in terms of mol%.
- substantially does not contain As 2 O 3 means that the glass component is not positively added with As 2 O 3 , but is allowed to be mixed at an impurity level. This means that the content of As 2 O 3 is less than 0.1 mol%.
- substantially free of Sb 2 O 3 but not added actively Sb 2 O 3 as a glass component, a purpose to allow the case to be mixed with impurity levels, specifically, Sb 2 It indicates that the content of O 3 is less than 0.1 mol%.
- Substantially no PbO means that PbO is not actively added as a glass component, but is allowed to be mixed at an impurity level. Specifically, the content of PbO is 0.1. It is less than mol%. “Substantially no F” means that F is not actively added as a glass component, but is allowed to be mixed at an impurity level. Specifically, the content of F is 0.1. It is less than mol%. If substantial addition of As 2 O 3 , Sb 2 O 3 , PbO, and F is excluded, it is possible to meet the environmental requirements of close relations.
- the tempered glass of the present invention has a glass composition of mol%, SiO 2 50-80%, Al 2 O 3 6.5-12.4%, Li 2 O 0-1%, Na 2 O 9-15. 5%, K 2 O 0-3.5%, MgO 0.1-2.5%, MgO + CaO + SrO + BaO 0-2.5%, substantially As 2 O 3 , Sb 2 O 3 , PbO and F It is preferable not to contain.
- “MgO + CaO + SrO + BaO” is the total amount of MgO, CaO, SrO and BaO.
- the tempered glass of the present invention has a glass composition of mol%, SiO 2 50 to 80%, Al 2 O 3 6.5 to 12.4%, B 2 O 3 0.01 to 15%, Li 2 O 0. ⁇ 1%, Na 2 O 9 ⁇ 15.5%, K 2 O 0 ⁇ 3.5%, Li 2 O + Na 2 O + K 2 O 9 ⁇ 16.5%, MgO 0.1 ⁇ 2.5%, MgO + CaO + SrO + BaO 0 It is preferable that it contains 1 to 2.5% and substantially does not contain As 2 O 3 , Sb 2 O 3 , PbO and F.
- “Li 2 O + Na 2 O + K 2 O” is the total amount of Li 2 O, Na 2 O and K 2 O.
