Abstract
The invention provides a milk white optical glass composition which comprises a base glass component and a milk white coloring agent, wherein the base glass component comprises the following ingredients in percent by weight: 81 percent by weight of SiO2, 2 percent by weight of Al2O3, 4 percent by weight of CaO, 4 percent by weight of MgO, 5 percent by weight of B2O3, 2 percent by weight of BaO and 2 percent by weight of TiO2; the milk white coloring agent comprises the following ingredients: 60-70 parts by weight of CaF2 and 30-40 parts by weight of SnO2; and the composition comprises 99.5 percent by weight of base glass component and 0.5 percent by weight of milk white coloring agent. Through reasonably adjusting a formula of the milk white optical glass composition, the chemical stability of glass is improved. The milk white optical glass composition is uniform in coloring, good in devitrification capacity and high in refractive index.
Description
Technical field
the present invention relates to a kind of oyster white optics glass composition, belong to optical element field.
Background technology
Color optical glass claims again optical lightscreening glass, and the spectral filter that it is mainly used to make observation, photograph, the instrument such as infrared, improves instrument visibility meter or meet some particular requirement to reach, and also can make tinted glasses.The effect of color optical glass is: the light that sees through specific wavelength that it can be selected; Can from discontinuous spectrum, isolate singlet line; Or by leaching the spectral range of certain width in continuous spectrum or evenly weakening spectrum of white light etc.
Existing oyster white optics glass composition, painted even not, crystallization ability, can not meet user's demand.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of oyster white optics glass composition is provided.
Oyster white optics glass composition of the present invention, is made up of parent glass composition and oyster white tinting material, and described parent glass comprises following composition according to weight percentage: 81% SiO2,2% Al
2o
3, 4% CaO, 4% MgO, 5% B
2o
3, 2% BaO and 2% TiO2, described oyster white tinting material comprises following composition: the SnO2 of the CaF2 of 60-70 weight part and 30-40 weight part, in described composition, the weight percentage of parent glass composition is 99.5%, and the weight percentage of oyster white tinting material is 0.5%.
Preferably,
Described oyster white tinting material comprises following composition: the SnO2 of the CaF2 of 65 weight parts and 35 weight parts.
The present invention, by rationally adjusting glass formula, has improved the chemical stability of glass, uniform coloring, and crystallization ability is good, and specific refractory power is high.
