Abstract
The invention discloses an aluminosilicate glass containing alkaline earth. The aluminosilicate glass comprises components at a mass ratio as follows: 48%-52% of SiO2, 0%-5.5% of B2O3, 12.5%-16.5% of Al2O3, 0%-7% of MgO, 5.5%-14% of CaO, 0%-8% of SrO, 15%-16% of BaO, 0%-2% of ZrO2, 0.001%-0.5% of CeO2 and 0.01%-2% of TiO2. The glass is particularly suitable for being used as a material for a halogen light bulb.
Description
Technical field
The invention belongs to field of glass production technology, be specifically related to a kind of alkaline earth aluminates glass.
Background technology
As the glass alkali-free metal oxide substantially of halogen light bulb, because alkalimetal ion is to the regenerate halogen circulation injurious effects of this lamp, result makes tungsten not be deposited on filament, but is deposited on inside this glass bulb as the black coating of destructiveness.
Summary of the invention
The object of the invention is to, a kind of alkaline earth aluminates glass is provided, be suitable as the bulb material of halogen light bulb.
Alkaline earth aluminates glass provided by the invention, its components in mass portion proportioning is: SiO
