Embodiment
For the ease of understanding the present invention, the present invention will be described more fully below.It is but of the invention
It can realize in many different forms, however it is not limited to embodiment described herein.On the contrary, provide
The purpose of these embodiments is to make the understanding more thorough and comprehensive to the disclosure.
The alumina silicate glass of one embodiment, include following component according to molar content meter:
60%~72% silica, 4%~9% alundum (Al2O3), 8%~15% sodium oxide molybdena, 0%~5%
Potassium oxide, 3%~9% calcium oxide and 1%~6% magnesia.
Silica (SiO2) it is to form composition necessary to alumina silicate glass skeleton.SiO2Manosil AS can be improved
The intensity of salt glass, chemical stability etc., the weight/mass percentage composition of silica is preferably 60%~72%.If
SiO2Weight/mass percentage composition less than 60%, then the weatherability of alumina silicate glass is inadequate；If more than 72%,
Alumina silicate glass becomes infusibility.
Alundum (Al2O3) (Al2O3) chemical stability and ion-exchange performance of alumina silicate glass can be improved,
It is to promote composition necessary to ion exchange, mass fraction is preferably 4%~9%.If Al2O3Quality hundred
Divide content less than 4%, then the ion-exchange capacity deficiency of alumina silicate glass, in predetermined chemical enhanced technique
Under be unable to reach required CS and DOL values；If more than 9%, the ion-exchange capacity of alumina silicate glass
Too strong, when carrying out antimicrobial treatment using two-step method, the ion exchange of the first step and fused salt is excessively abundant, and the
The introduction volume deficiency of two step antibacterial ions, so as to influence anti-microbial property.Al simultaneously2O3Too high levels also result in
The viscosity increase of glass, is unfavorable for melting and clarifies.
Sodium oxide molybdena (Na2O the fusion temperature of alumina silicate glass) can be significantly reduced, is that the chemical enhanced institute of progress is required

The weatherability deficiency of glass.
Calcium oxide (CaO) can reduce the viscosity of alumina silicate glass in high temperature, promote the molten of alumina silicate glass
Change and clarify, but it has inhibition to ion exchange, its weight/mass percentage composition is preferably 3%~7%.
If CaO weight/mass percentage composition is less than 3%, the viscosity of alumina silicate glass is too big, it is difficult to melt, if
Higher than 9%, then the devitrification resistance of alumina silicate glass deteriorates, while ion-exchange performance reduces.Meanwhile aluminium
The material of silicate glass is too short, is unfavorable for being molded.
Magnesia (MgO) is that the high-temperature viscosity for making alumina silicate glass reduces and improves meltbility and mouldability
Composition.If its weight/mass percentage composition is less than 1%, the significant effect for improving meltbility can not be obtained；Such as
Fruit weight/mass percentage composition is higher than 6%, the easy devitrification of alumina silicate glass.Magnesia weight/mass percentage composition is preferably
1~6%.
