Abstract
The invention relates to optical glass for manufacturing crystal handicraft articles, in particular to composite optical glass which is formed by combining optical glass with high density and adamantine luster and low-density optical glass. The composite optical glass is characterized in that the composite optical glass is formed by combining the high-density optical glass and the low-density optical glass, wherein the high-density optical glass adopts optical glass with ultrahigh refractive index and comprises the following compositions by weight percentage: 1 to 18.3 percent of SiO2, 4 to 26.7 percent of B2O3, 6 to 36.4 percent of TlO2, 2.1 to 18.6 percent of ZnO, 16.3 to 40.5 percent of BaO, 1 to 16.5 percent of SrO/MgO/CaO, 1 to 10.3 percent of Ta2O5, 6 to 30 percent of La2O3/Bi2O3 and 5.4 to 26.9 percent of Y2O3/ZrO2/Nb2O5. Due to the ultrahigh refractive index, the high-density optical glass has special adamantine luster.
Description
Technical field
The present invention is a kind of opticglass that crystal works is made that is used for, and particularly a kind of have the opticglass of adamantine luster and the composite optical glass of low density opticglass be combined into high-density.
Background technology
Common synthetic quartz is the glass that contains plumbous oxide, generally contains 24% plumbous oxide, and the composition that contains plumbous oxide is high more, and refractive index and hardness are high more, and it is pure sparkling and crystal-clear and be rich in adamantine luster that finished product just seems more, is difficult to cutting simultaneously more, and finished product are also just rare more.The key distinction of opticglass and simple glass: opticglass has the transparency of height, physics and chemically high homogeneity and specific and accurate optical coefficient.The gloss of the diamond-like that the opticglass with high index (more than 1.9) is often can be pure sparkling and crystal-clear and bright, as the manufacturing that is used for artwork must obtain people's favor.Yet,, seldom adopted because it involves great expense.
Summary of the invention
The objective of the invention is to overcome the defective of prior art; A kind of opticglass that crystal works is made, particularly a kind of composite optical glass and method of manufacture thereof that high-density is had the opticglass and the low density opticglass be combined into of adamantine luster of being used for proposed.
The objective of the invention is to realize through following technical scheme: a kind of composite optical glass that is used for the crystal works manufacturing is characterized in that highdensity opticglass and low density opticglass are composited.Wherein said high-density adopts the opticglass with extra-high-speed specific refractory power, and it has following component:

All percentage ratios are weight percentage.
Optical theory is told us, and only a kind of hertzian wave also has the general characteristic of ripple.Advance when running into the interface of different media when ripple, have wave reflection partly, remaining ripple then possibly get into new medium.For example: when the vertical directive glass of visible light, 4% luminous reflectance is arranged approximately, all the other light of 96% then get in the glass.And when low density glass gets into high-density glass, can produce reflection and refraction at the interface of two media when light, when highdensity light is passed in refraction, when getting into low density glass, can produce reflection and refraction at its interface again.Refraction effect just originates from ripple different travel rate in different media.Because the opticglass of different densities is compounded in one, formed a plurality of medium interfaces, specific refractory power surpasses common quartzy 10%, and is more dazzling brilliant.

Embodiment
Embodiments of the invention are provided by following specific embodiments:
At first, make high-density optical glass according to following prescription,
| Composition | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| ?SiO 2 | ?18 | ?3 | ?12 |
| ?B 2O 3 | ?6 | ?19 | ?11 |
| ?TlO 2 | ?33 | ?21 | ?9 |
| ?ZnO | ?4 | ?3 | ?10 |
| ?BaO | ?16 | ?16 | ?21 |
| SrO or MgO or CaO | ?2 | ?8 | ?9 |
| ?Ta 2O 5 | ?2 | ?10 | ?5 |
| ?La 2O 3Or Bi 2O 3 | ?6 | ?9 | ?11 |
| ?Y 2O 3Or ZrO 2Or Nb 2O 5 | ?13 | ?11 | ?12 |
All percentage ratios are weight percentage.The glass of gained has the extra-high-speed specific refractory power, more than 1.95.Again that specific refractory power is lower opticglass like common K9 glass, is compounded in one with the described structure of Fig. 1, forms composite optical glass.The compound mode can be that tackiness agent binds or other modes.Because the specific refractory power of extra-high-speed makes this high-density glass have special adamantine luster; Its high dispersivity makes white light be separated into the shades of colour in the spectrum when passing this high-density glass simultaneously, seems more dazzling, produces " fire is color ".And, increased " adamantine luster " and " fire coloured silk " phenomenon like this because compound high-density glass makes light on two kinds of interfaces, produce refraction and reflection.
Claims (2)
