Definitions
- the present invention relates to glass, glass sheets for reinforcement, and reinforced glass sheets that have excellent chemical durability and formability.
- the present invention relates to reinforced glass sheets that are suitable for flexible cover members such as foldable displays.
- alkali aluminosilicate glass has been used for a variety of purposes due to its excellent properties.
- JP 2006-83045 A International Publication No. 2015/031188 International Publication No. 2013/063275
- the molar ratio ( Li2O + Na2O + K2O )/ Al2O3 is preferably 2 or more. This can improve formability.
- “( Li2O + Na2O + K2O )/ Al2O3 " refers to the value obtained by dividing the total content of Li2O , Na2O , and K2O by the content of Al2O3 .
- the glass of the present invention is preferably the glass described in any one of (1) to (11) above, which is subjected to an ion exchange treatment.
- the tempered glass sheet of the present invention is preferably the tempered glass described in (13) above, and has a thickness of 0.2 mm or less.
- the glass of the present invention contains, in mole percent, 60-85% SiO 2 , 1-20% Al 2 O 3 , 0-5% B 2 O 3 , 1-20% Li 2 O + Na 2 O + K 2 O , and 0-5% MgO + CaO + SrO + BaO.
- % means "mol %” unless otherwise specified.
- the content of SiO 2 is preferably 60% or more, 65% or more, 66% or more, 70% or more, 72% or more, 73% or more, 74% or more, particularly 75% or more, and preferably 85% or less, 84% or less, 83% or less, 82.5% or less, 82% or less, 81.5% or less, particularly 81% or less.
- the content of Al2O3 is preferably 1% or more, 2% or more, 2.5% or more, 3% or more, 3.5% or more, 4% or more, 4.5% or more, 4.6% or more, 4.7% or more, 4.8% or more, 4.9% or more, particularly 5% or more, and is preferably 20% or less, 15% or less, 13% or less, 12% or less, 11% or less, 10% or less, 9.5% or less, 9% or less, 8.5% or less, 8% or less, 7.5% or less, particularly 7% or less.
- Li 2 O has the effect of lowering the viscosity of glass and improving melting and moldability.
- Li 2 O has the highest effect of lowering the viscosity of glass, followed by Na 2 O and K 2 O in that order.
- it is a component capable of forming a compressive stress layer on the glass surface by ion exchange with Na ions or K ions, and is a component particularly effective for obtaining a deep stress depth.
- the content of Li 2 O is too high, the chemical durability is likely to decrease, and it is a component that dissolves during ion exchange treatment and deteriorates the ion exchange solution.
- the suitable content of Li 2 O varies depending on the characteristics of the glass that are important.
- the content of Li 2 O is preferably 0 to 10%, 0 to 9%, 0 to 8%, 0 to 7%, 0 to 6%, 0 to 5%, 0 to 4%, and particularly 0 to 3%.
- the content of Li 2 O is preferably 0.1 to 15%, 1 to 14.9%, 2 to 14.8%, 3 to 14.7%, 4 to 14.6%, 5 to 14.5%, 6 to 14.4%, 6.5 to 14.3%, 7 to 14.2%, 7.5 to 14.1%, and particularly 8 to 14%.
- the content of Li 2 O is preferably 1 to 14%, 1.5 to 13%, 2 to 12%, 2.5 to 11%, 2.6 to 10%, 2.7 to 9.5%, 2.8 to 9%, 2.9 to 8.5%, and particularly 3 to 8%.
- the content of Li 2 O is 10% or less, devitrification is less likely to occur.
- the content of Na 2 O is preferably 1 to 14%, 1.5 to 13%, 2 to 12%, 2.5 to 11%, 2.6 to 10%, 2.7 to 9.5%, 2.8 to 9%, 2.9 to 8.5%, particularly 3 to 8%.
- the molar ratio (Li 2 O + Na 2 O + K 2 O) / Al 2 O 3 is preferably 5 or less, 4 or less, 3.5 or less, 3.4 or less, 3.3 or less, 3.2 or less, 3.1 or less, particularly 3 or less.
- the content of MgO+CaO+SrO+BaO is preferably 0-5%, 0-4%, 0-3.7%, 0-3%, 0-2%, 0-1%, 0-0.9%, 0-0.8%, 0-0.7%, 0-0.6%, 0-0.5%, 0-0.4%, 0-0.3%, 0-0.2%, and especially 0-0.1%.
- CaO is one of the components that cuts the network structure of glass, like alkali metal oxides, reduces high-temperature viscosity, and improves meltability and formability. It is also a component that affects chemical durability. If the CaO content is too high, there is a risk of chemical durability decreasing. Furthermore, CaO is also a component that is prone to causing a decrease in ion exchange performance and deterioration of the ion exchange solution.
- the BaO content is preferably 0-1%, 0-0.9%, 0-0.8%, 0-0.7%, 0-0.6%, 0-0.5%, 0-0.4%, 0-0.3%, 0-0.2%, 0-0.1%, 0-0.01%, 0-less than 0.01%, and particularly 0-0.001%. If the BaO content is too high, chemical durability is likely to decrease.
- CaO is a component that reduces ion exchange performance.
- the molar ratio (MgO+CaO+SrO+BaO/(1-CaO) is preferably 0-10, 0-5, 0-4, 0-3.7, 0-3, 0-2, 0-1, 0-0.9, 0-0.8, 0-0.7, 0-0.6, 0-0.5, 0-0.4, 0-0.3, 0-0.2, and especially 0-0.1.
- the molar ratio (Li 2 O + Na 2 O + K 2 O + MgO + CaO + SrO + BaO-Al 2 O 3 ) / (SiO 2 + Al 2 O 3 + B 2 O 3 ) means the ratio of the component that cuts the network structure in the glass to the component that forms the network structure in the glass.
- alkali metal oxides and alkaline earth metal oxides have the effect of cutting the network structure in the glass, but since Al 2 O 3 forms a network structure in the glass together with alkali metal oxides, an alkali metal oxide with the same content as Al 2 O 3 does not have the effect of cutting the network.
- SiO 2 , Al 2 O 3 and B 2 O 3 are components that form a network structure in the glass.
- TiO2 like Fe2O3 , is a component that is mixed in as an impurity from glass raw materials and manufacturing equipment. If the TiO2 content is too high, the glass will be colored black and the transmittance of visible light will decrease. Therefore, the TiO2 content is preferably 0-0.5%, 0-0.3%, 0-0.1%, 0-0.05%, 0-0.04%, and particularly 0-0.03%.
- R 2 O+R'O-Al 2 O 3 )/(SiO 2 +Al 2 O 3 +B 2O3 ) means the molar ratio ( Li2O + Na2O + K2O +MgO+CaO+SrO+BaO- Al2O3 )/( SiO2 + Al2O3 + B2O3 ).
