1. a kind of alumina silicate glass, which is characterized in that indicated with the mass percentage of following oxide benchmarks, including as followsComponent:

  • 56.0%~68.0% silica, 10.0%~22.0% alundum (Al2O3), 9.0%~15.0% oxidationSodium, 2.0%~8.0% magnesia, 0%~9.0% potassium oxide and 0.2%~1.5% zirconium dioxide;

    Wherein, the gross mass percentage composition of the silica and the alundum (Al2O3) is more than or equal to 70% and is less than or equal to85%, the gross mass percentage composition of the sodium oxide molybdena and the potassium oxide more than or equal to 9% and is less than or equal to 23%;

    The aluminium siliconNeutralc tint is presented in silicate glass chromatic value, and the alumina silicate glass is converted into the CIE Lab face under the equivalent thickness of 1.1mmIt is -0.05~0.05, b* values is 0.05~0.17 that chroma color index, which is L* values >

    =96.70%, a* value, light transmittance >

    =91.60%;

    Contain the sulfur trioxide no more than 0.08% in the alumina silicate glass;

    Contain in the alumina silicate glass and is no more than0.018% di-iron trioxide;

    When prepared by the alumina silicate glass, weighs corresponding raw material by the mass percentage of each oxide benchmark and mix and addHeat fusing obtains glass metal aftershaping, wherein alundum (Al2O3), sodium oxide molybdena in the alumina silicate glass, magnesia, oxidationAt least one of potassium and zirconium dioxide are introduced at least partially by the form of nitrate in the preparation, or ammonium nitrate and its is addedHis raw material carries out heating melting and obtains glass metal together, wherein and the mass ratio of ammonium nitrate and glass metal is 0.1~5.5;

    100,When preparation, it is added into raw material after carbon dust and fining agent and carries out heating melting and obtain glass metal, wherein the fining agent is selected fromSnO2And SnCl2At least one of, the mass ratio of carbon dust and glass metal is 0.0001~0.25;

    100.
