Description
Technical field
The present invention relates to a kind of heat-protecting glass composition, belong to optical element field.
Background technology
Color optical glass is also known as optical lightscreening glass, and it is mainly used to make the optical filtering of the instrument such as observation, photograph, infrared
Piece, to reach raising instrument visibility or meet some particular/special requirements, can also make tinted glasses.The effect of color optical glass
It is：The light for the transmission specific wavelength that it can be selected；Singlet line can be isolated from discontinuous spectrum；Or by continuous light
Spectral region or the uniform spectrum for weakening white light of one fixed width etc. are filtered out in spectrum.
Existing heat-protecting glass composition, crystal grain distribution is not uniform enough, crystallization ability, it is impossible to meet the demand of user.
The content of the invention
The purpose of the present invention is to overcome in place of the deficiencies in the prior art that there is provided a kind of heat-protecting glass composition.
The heat-protecting glass composition of the present invention, is made up of, described parent glass is pressed parent glass composition and heat-insulated auxiliary agent
Include following component according to parts by weight：SiO270-80 parts by weight, Al2O35-10 parts by weight, BaO 5-10 parts by weight, P2O5 5-
10 parts by weight, TiO2 5-10 parts by weight, described heat-insulated auxiliary agent is Y2O3, described heat-insulated auxiliary agent is 2- in the content of composition
5 parts by weight.
Preferably,
Described heat-protecting glass composition, is made up of, described parent glass is according to weight parent glass composition and heat-insulated auxiliary agent
Number includes following component：SiO275 parts by weight, Al2O38 parts by weight, the parts by weight of BaO 7, P2O56 parts by weight, TiO2 7 weights
Part is measured, described heat-insulated auxiliary agent is Y2O3, described heat-insulated auxiliary agent is 3 parts by weight in the content of composition.
The present invention improves the chemical stability of glass by Reasonable adjustment glass formula, and crystal grain distribution is uniform, crystallization energy
Power is good, and refractive index is high.
