Abstract

The present invention relates to radioresistant optical glass which contains 2 to 5 wt% of Na2O, 4 to 8 wt% of K2O, 40 to 45 wt% of SiO2, 0.1 to 1 wt% of CeO2 and 45 to 53 wt% of PbO. The radioresistant optical glass has the advantages of radioresistant performance, A class air bubbles and B class stripes and can be continuously produced by a tank furnace.

Description

Radiation hardness opticglass
Technical field
The present invention relates to a kind of opticglass, particularly relate to a kind of radiation hardness opticglass.
Background technology
Because after high energy particle and high-energy radiation act on general opticglass, will ultraviolet, visible and region of ultra-red produce a series of by glass in oxygen ion vacancy combine the colour center that is produced with free electron, thereby cause the transmitance of glass to descend greatly, and mainly show ultraviolet and visible region, very little in the transmitance change of near infrared region glass.In order to guarantee having under the radiating environment opticglass can works better, must the corresponding radioresistive glass of invention.Existing a prescription, its weight percent consists of: SiO 2: 41.36; Pb 3O 4: 51.33; KNO 3: 2.75; K 2CO 3: 4.26; CeO 2: 0.30, but in this prescription since all the use sylvite flux, make the high temperature viscosity of glass bigger, cause the striped of glass and bubble poor, bubble is the B level, striped is the C level, is unfavorable for the production of glass.
Summary of the invention
The purpose of this invention is to provide a kind of radiation-resistant opticglass, the bubble of described opticglass is the A level, and striped is the B level, is suitable for the tank furnace continuous production.
The technical scheme of technical solution problem of the present invention is: the weight percentage composition of described opticglass comprises: Na 2O:2%～～3.45%; K 2O:4%～～8%; SiO 2: 40%～～45%; CeO 2: 0.1～～1%; PbO:45%～～53%; BaO:0～～1%.
The invention has the beneficial effects as follows: owing to used sodium salt and sylvite to flux in this prescription simultaneously, the high temperature viscosity of glass is reduced, indexs such as the bubble of the glass of producing, striped have all improved 1-2 rank than original formulation.
Embodiment
Improve the radiation resistance of opticglass to ray, can in forming, introduce in glass the high oxide of a small amount of valence variation element, after making the glass raying, the radiating energy at first is used for changing their valence, becomes at a low price by high price, and the change of these oxide atomic valencys, in visible-range, do not produce absorption, so do not cause the change in color of glass, by experiment, find to introduce CeO 2More suitable.CeO 2After the introducing, quaternary Ce after being subjected to radiation 4+Become tervalent Ce according to following formula 3+: Ce 4++ e -=Ce 3+So, the radiating energy just consumes in the transformation of ion valence mumber, rather than is consumed in the formation of colour center.Ce 4+And Ce 3+Absorption all is positioned at ultraviolet band to radiating, can not cause the variation of glass colour.In addition, CeO 2Can also replace Sb 2O 3Play finings.Experiment is found, introduces 0.1%～～1% CeO 2After, the radiation resistance of the glass of producing is good, and optical constant meets the requirements, and is suitable for the tank furnace continuous production.
SiO 2With PbO be the generation body of glass.SiO 2In glass, has low-refraction, the character of low-expansion coefficient and big high temperature viscosity.Therefore in this invention, work as SiO 2＞65% o'clock, the high temperature viscosity of glass was big especially, was unfavorable for the production of glass, so add-on is controlled at 40%～～45%.PbO has high refractive index and low-melting characteristic in glass, it mainly works to help fusing, reduce glass high temperature viscosity, by test, it is 45%～～53% proper that the content of PbO is controlled at.In this prescription, also can use Pb 3O 4Replace PbO, but because Pb 3O 4Purity low, foreign matter content is than higher, so the luminous absorptance of glass is relatively poor.
Na 2O adds as fusing assistant.Its introducing helps reducing the high temperature viscosity of glass, but Na 2O also can increase the thermal expansivity of glass, reduces thermostability, chemical stability and the physical strength of glass.Be controlled at 2%～～3.45% proper by the content of testing it.
K 2O also adds as fusing assistant.Its introducing can increase the gloss and the transparency of glass.Be controlled at 4%～～8% proper by the content of testing it.
BaO mainly works to adjust the chromatic dispersion of glass, and its content is controlled at 0～～1%.
Be the contrast of 4 embodiment each side parameters of the present invention below, numerical value numerical value that is weight percentage of each prescription in the table.
Embodiment 1 2 3 4
SiO 2 44.80 43.00 41.00 42.00
PbO 46.50 48.50 50.30 52.70
Na 2O 3.00 2.70 3.30 3.45
K 2O 5.30 5.50 5.00 4.90
BaO 0.20 0.30 0.25 0.20
CeO 2 0.20 0.20 0.15 0.15
ΔD1/cm 0.046 0.048 0.045 0.043
nd 1.6450 1.6474 1.6478 1.6482
As can be seen from the above table, the present invention is by adjusting the compositing formula of glass, make glass have radiation resistance Δ D1/cm≤0.080, specific refractory power is 1.6450-1.6500, and the photoabsorption of the glass of producing through tank furnace is brought up to 3 classes by 4 classes, bubble is brought up to the A level by the B level, and striped is brought up to the B level by the C level, has all improved 1-2 rank than original formulation.
