Specific embodiment
In the following, the embodiment of optical glass of the invention is described in detail, but the present invention is not limited to following realities
Mode is applied, change appropriate can be carried out in the range of the object of the invention to be implemented.In addition, about repetitive specification,
Although there is the case where omitting the description appropriate, but not therefore limit the purport invented.Sometimes this is sent out in the following contents
Bright optical glass is referred to as glass.
[optical glass]
The each component range of optical glass of the present invention is illustrated below.In the present specification, if without special theory
Bright, the content of each component is all using the weight percent table of the glass substance total amount relative to the component for being converted into oxide
Show.Herein, described " component for being converted into oxide " refers to, as optical glass composition component of the invention raw material and make
In the case that oxide, complex salt and hydroxide etc. decompose when melting and are changed into oxide, by the object of the oxide
Matter total amount is as 100%.
Unless in particular situations it is further noted that numberical range listed herein includes upper and lower bound value, " more than "
" following " includes endpoint value, and including all integers and score in the range, and is not limited to limited range when institute
The occurrence of column.Herein referred "and/or" is inclusive, such as " A and/or B ", refers to only A, or only B, Huo Zhetong
When have A and B.
<necessary component and optional components>
SiO2Exist in the present invention as skeleton, be necessary component of the invention, by the SiO for introducing 56% or more2,
Have the function of improving the thermal stability of glass, is also effective in terms of obtaining suitable for the viscosity of forming when being shaped to glass solution
, when its content is more than 68%, the melting behaviour of glass deteriorates, and transition temperature increases.Therefore the present invention in introduce 56~
68% SiO2, it is preferably introduced into greater than 60% but is less than or equal to 66% SiO2。
B2O3And the oxide of glass is formed, when its content is more than 10%, the refractive index of glass is reduced, fusion process
Middle volatility increases, and the chemical stability of the optical constant fluctuation and glass that cause glass is deteriorated, desired to obtain having
Optical constant range and the optical glass with excellent chemical stability, B2O3Content be limited to 0~10%, preferred content
It is 0~5%, more preferably 0~2%, does not introduce further preferably.
TiO2Have the function of improving glass refraction, glass network can be participated in and formed, while the machine of glass can also be improved
Tool performance and chemical stability can not obtain said effect when its content is less than 15%, but when its content is more than 25%
When, glass is easy crystallization, and the shortwave transmitance of glass deteriorates.Therefore, TiO2Content be limited to 15~25%, preferably
17~21%.
It is found through inventor's lot of experiments, if TiO in the present invention2/SiO2Lower than 0.23, on the transition temperature of glass
It rises, chemical stability decline；If but TiO2/SiO2More than 0.43, then the devitrification resistance of glass can aggravate, therefore the present invention
Middle TiO2/SiO2Range be 0.23~0.43, preferably 0.25~0.4, more preferably 0.27~0.37.
Na2O is necessary component of the invention, not only has the function of reducing the transition temperature of glass, but also there are also relatively strong
Fluxing action.Relative to K2O, Na2O can make high temperature viscosity of glass become smaller, and be conducive to the elimination of bubble and striped.But work as it
It is unobvious to reduction transition temperature and fluxing effect when content is lower than 6%, if its content is higher than 16%, glass devitrification
Property and chemical stability sharply decline.Therefore, Na2The content range of O is 6~16%, preferably 10~15%.
K2O also has the function of reducing the transition temperature of glass and fluxing.Relative to Na2O, K2O can improve the saturating of glass
Lightness and gloss improve the devitrification resistance energy of glass.K in the present invention2The content range of O is 1~11%, preferably 3~8%.
It is found through inventor's lot of experiments, passes through control (Na2O+K2O)/TiO2Value 0.5 or more, can be easier to same
When obtain the optical glass with low transition temperature and low density, but as (Na2O+K2O)/TiO2Value be more than 1.5, glass
Chemical stability reduces.Therefore, (Na in the present invention2O+K2O)/TiO2Range be 0.5~1.5, preferably (Na2O+K2O)/TiO2
Range be 0.7~1.3, more preferable (Na2O+K2O)/TiO2Range be 0.8~1.2, further preferred (Na2O+K2O)/
TiO2Range be 0.9~1.1.
In certain embodiments of the present invention, by making Na2O/K2O can make glass with excellent in 0.9~5 range
Different bubble degree and striped significantly improve the chemical stability of glass, preferably Na while spending2O/K2O is 1.2~4, more preferably
Na2O/K2O is 1.5~3.
Li2O also has the function of reducing glass transformation temperature, but when its content is more than 5%, the devitrification resistance of glass is disliked
Change, and Li2O will lead to the seriously corroded of platinum crucible, therefore Li in the present invention2O content is 0~5%, preferably 0~3%, more
Preferably 0~1%, it does not introduce still more preferably.
Alkaline earth oxide RO is one of MgO, CaO, SrO and BaO or a variety of, and a small amount of introduce can improve glass
Devitrification resistance and chemical stability, when its content is more than 5%, the tendency towards devitrification of glass increases, therefore RO draws in the present invention
Entering amount is 0~5%, preferably 0~2%, more preferably 0~1%.In some embodiments, it is preferred RO is BaO.
Sb2O3、SnO2, SnO and CeO2One or more of component can be used as clarifying agent addition, by adding on a small quantity
Sb2O3、SnO2、CeO2The clarifying effect of glass can be improved in component, but works as Sb2O3When content is more than 1%, glass has Clarification Performance
Reduced tendency, simultaneously because its strong oxidation promotes the deterioration of shaping dies, therefore Sb of the present invention2O3Additive amount be
1% hereinafter, preferably 0.5% or less.SnO2, SnO can also be used as clarifying agent to add, but when its content is more than 1%, glass
Glass can colour, or when heat, soften glass and carry out die forming etc. shape again when, what Sn can become that nucleus generates rises
Point generates the tendency of devitrification, therefore SnO of the invention2With the difference content of SnO be 1% hereinafter, preferably 0.5% hereinafter, into
One step does not preferably introduce.CeO2Effect and additive amount ratio and SnO2Unanimously, content be 1% hereinafter, preferably 0.5% with
Under, it does not introduce further preferably.
While to make optical glass of the present invention be easier to obtain desired refractive index and Abbe number, resulting optical glass tool
There are lower transition temperature and density and excellent chemical stability, preferably SiO2、TiO2、Na2O and K2Total content of O
It is 95% or more, more preferable SiO2、TiO2、Na2O and K2Total content of O is 98% or more, further preferred SiO2、TiO2、
Na2O and K2Total content of O is 99% or more.
<component that should not contain>
In glass of the present invention, the oxide of the transition metal such as V, Cr, Mn, Fe, Co, Ni, Cu, Ag and Mo, even if individually
Or in the case that compound ground contains on a small quantity, glass is also subject to coloration, the specific wavelength in visible light region generates absorption, thus
The property for weakening raising visible light transmittance effect of the invention, therefore it is desirable, especially for the transmitance of visible light region wavelength
The optical glass required, does not preferably contain actually.
The oxide of Th, Cd, Tl, Os, Be and Se have what control used to incline as harmful chemical substance in recent years
