Definitions
- Chemically strengthened glass sheets are finding increasing applications in specialized glazing jobs where a mechanical resistance is required/mandatory, in a monolithic or laminated form, like transportation (i.e. aeronautical, automotive), building/architecture and display industries.
- the display industry has become in the several past years a huge market on demand for chemically strengthened transparent glass sheets as protective/cover glass, viewing window or (touch)screen for numerous electronic devices like mobile phones, smartphones, TV, computers, digital cameras, etc. Indeed, as many of these devices are portable, the glass used is mechanically solicited a lot and it is therefore highly desirable that it is able to tolerate impact and/or damage, such as scratches or impact, during use and transport.
- Chemical strengthening is even more of great importance in the domain of displays because such a domain requires glass sheets of low thickness (as low as less than 1 mm) and because chemical strengthening is known as the process of choice to mechanically reinforce (ultra-)thin glass sheets. For weight reasons, it is also advantageous to use thin glass sheets as cover glass for solar, thermal or photovoltaic devices.
- the chemical strengthening of a glass article is a heat induced ion-exchange, involving replacement of smaller alkali sodium ions in the surface layer of glass by larger ions, for example alkali potassium ions.
- Increased surface compression stress occurs in the glass as the larger ions “wedge” into the small sites formerly occupied by the sodium ions.
- Such a chemical treatment is generally carried out by immerging the glass in an ion-exchange molten bath containing one or more molten salt(s) of the larger ions, with a precise control of temperature and time. The rupture strength of a glass article which has been so treated is thus increased by a value approximately equal to the surface compressive stress generated.
- CS surface compressive stress
- DoL depth of layer
- the two strengthening parameters also depend significantly, for a given glass composition, on the conditions of temperature and time of the ion exchange process.
- the thickness of the layer under compression increases with the temperature and with the duration of the ion-exchange according to the known diffusion laws.
- the higher the temperature the more rapidly the stresses induced by the ion exchange relax.
- extending the treatment for a too long period allows giving the stresses the necessary time to relax and thus results in a less degree of toughening.
- the conditions to be chosen for the process therefore reside generally in a compromise between the optimum temperature and the minimum duration, to optimize process cost.
- Aluminosilicate-type glass compositions such as for example those described in US Patent Application US2012/0196110 A1, the GORILLA® glass product from Corning or the DragonTrail® glass product from Asahi Glass Co., are also known to be very efficient for chemical tempering. However, they have a lot of drawbacks. Their high temperature properties make them very difficult to produce (viscosity, fining ability, forming, refractories corrosion). Their cost is relatively high due to expensiveness of some raw materials to use (i.e. alumina) and due to the high temperatures required for their production (high content of energy/fuel).
- the transition time while changing from a composition to another is one parameter which is of high importance when producing glass, because if long, the production cost of the final glass is drastically negatively impacted.
- the objective of the invention in particular is to remedy the cited disadvantages and resolving the technical problem, i.e. to provide a glass composition which is easy chemically temperable or, in other words, more favourable to ion exchange than conventional soda-lime-silica glass compositions.
- Another objective of the invention in at least one of its embodiments is to provide a glass composition which is easy chemically temperable and which allows reaching strengthening parameters appropriate for a “piece-by-piece” process used to produce cover glass for display devices (edge strength obtained typically by DoL>10-15 microns).
- an objective of the invention in such a context is to provide a glass composition which is easy chemically temperable and which allows obtaining great exchange depth, while keeping compressive stress values that result in a better reinforcement of glass.
- Another objective of the invention in at least one of its embodiments is to provide a glass composition which is easy chemically temperable and easy to produce, in particular on an existing line of production of classical soda-lime-silica glass.
- an objective of the invention in such a context is to provide a glass composition which is easy chemically temperable and which does not require long transition time when passing from the production of the classical soda-lime-silica composition to the temperable composition (and vice-versa).
- an objective of the invention is to provide a glass composition which is easy chemically temperable and which does not require to use raw materials, techniques and/or industrial installations which are different from those employed for classical soda-lime-silica glass ordinary produced (or, in other words, compatible with classical float process).
- an objective of the invention in at least one of its embodiments is to provide a glass composition which is easy chemically temperable and with targeted properties (lower viscosity, lower working point temperature, melting point ⁇ 1550-1500° C., sulfates fining ability, low refractories corrosion, appropriate devitrification temperature), thereby avoiding known drawbacks of alumino-silicate composition and making composition compatible with existing tools for production of soda-lime glass.
- Another objective of the invention is to provide a solution to the disadvantages to the prior art that is simple, quick and, above all, economical.
- the invention relates to a glass sheet having a boron- and lithium-free glass composition comprising the following in weight percentage, expressed with respect to the total weight of glass:
- the invention rests on a novel and inventive approach, since it enables a solution to be found for the disadvantages of prior art, in particular the disadvantages of aluminosilicate glasses while keeping, at least partially, their advantages.
- the inventors have indeed found that it is possible to obtain an easy chemically temperable glass sheet which is unexpensive and easy to mass produce by combining in a soda-silica glass matrix, a very low alumina and CaO content and a “reverse” CaO/MgO ratio in comparison with classical industrial glass compositions (including soda-lime-silica and aluminosilicate glasses, with typical values for that ratio above 1).

- the glass sheet of the invention is able to be chemically tempered or, in other words, ion-exchangeable/able to undergo an ion-exchange.
- enrichment in tin is understood to mean an increase in the concentration of tin with respect to the composition of the glass at the core, which may or may not be substantially zero (devoid of tin). Therefore, a float glass sheet can be easily distinguished from sheets obtained by other glassmaking processes, in particular by the tin oxide content which may be measured, for example, by electronic microprobe to a depth of ⁇ 10 microns. In many cases and as illustration, this content lies between 1 and 5 wt %, integrated over the first 10 microns starting from the surface.
