Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described in further detail.

[0030] 1. Aluminosilicate glass

[0031] The aluminosilicate glass according to the embodiment of the present invention, based on oxides, by mass percentage, includes:

[0032]

[0033] At the same time, the aluminosilicate glass also includes 150ppm-550ppm Fe 2 o 3 , and Fe 2 o 3 When it is 150ppm~300ppm, the ratio Redox of ferric ion mass to all iron ion mass is 35~45%; Fe 2 o 3 When the concentration is 300ppm-550ppm, the ratio Redox of the mass of divalent iron ions to the mass of all iron ions is 25-35%.

[0034] Preferably, the aluminosilicate glass, based on oxides, includes by mass percentage:

[0035]

[0036] At the same time, the aluminosilicate glass also includes 150ppm-550ppm Fe 2 o 3 , and Fe 2 o 3 When it is 150ppm~300ppm, the ratio Redox of ferric ion mass to all iron ion mass is 35~45%; Fe 2 o 3 When the concentration is 300ppm-550ppm, the ratio ...

Abstract

The invention discloses aluminosilicate glass and a preparation method thereof. The aluminosilicate glass is prepared from the following components in percentage by mass: 59 to 70 percent of SiO2, 13to 23 percent of Al2O3, 5 to 15 percent of Na2O, 0.1 to 6 percent of K2O, 0 to 0.1 percent of CaO, 1 to 7 percent of MgO, 0.2 to 2 percent of ZrO2, 0 to 4.5 percent of B2O3, 0 to 4 percent of Li2O and150 to 550 ppm (Parts Per Million) of Fe2O3, when the content of Fe2O3 is 150 to 300 ppm, a value of Redox ranges from 45 percent to 35 percent; when the content of Fe2O3 is 300 to 550 ppm, the valueof the Redox ranges from 35 percent to 25 percent. According to the aluminosilicate glass disclosed by the invention, the glass melting temperature is reduced while good transmittance is ensured, sothat the production cost of the aluminosilicate glass is reduced.

Description

technical field [0001] The invention relates to the field of glass, in particular to aluminosilicate glass and a preparation method thereof. Background technique [0002] At present, the thickness of high-alkali high-aluminosilicate glass used in the touch cover field is generally less than 3mm. Under the same conditions, the thinner the glass, the higher the transmittance, the brighter the protected display device, the more power consumption of the display device can be saved, and the standby time of mobile touch products can be extended. And in the composition of the glass Fe 2 o 3 It mainly plays a coloring role and affects the transmittance of the glass. Therefore, in order to obtain higher transmittance, Fe in the glass is required 2 o 3 content as low as possible. [0003] In general, the transmittance of a glass plate with the same thickness varies with the Fe in the glass plate 2 o 3 content decreased and increased. However, when the thickness of the glass p...
