Samarium powder；Mix according to the mass percent accurate weighing given by component and uniformly, be prepared into batch；This batch is thrown
Enter in glass-melting furnace and founded, glass melting temperature is controlled at 1600 DEG C ~ 1650 DEG C；It is formed subsequently into molten tin bath, shaping temperature
Scope control is spent at 850 DEG C ~ 1450 DEG C；Annealing kiln annealing is finally entered, initial annealing temperature is 600 DEG C ~ 650 DEG C.
Brief description once of the invention each component property：
Si02It is glass network former oxide, the mechanical strength, chemical stability, heat endurance of glass can be improved
Deng, but it is more infusibilized material again；Si02It is 57~59% to be adapted to content range.
Ge forms tetrahedral network in glass as Si, but Ge ionic radius are more than Si, with a small amount of GeO2Substitute
Si02Afterwards, Ge4+High price cation can significantly improve velocity of ion exchange, improve the tempering intensity of glass, GeO2It is adapted to content
Scope is 2~3%.
Al2O3, under equal tempering conditions, aluminium content is the major influence factors of ion-exchange effect in glass, Al2O3
Mainly with [AlO in glass4] tetrahedral geometry presence.[AlO4] volume be 41cm3/ mol, [SiO4] volume be 27.24
cm3/ mol, i.e. [AlO4] tetrahedron space is more than [SiO4], Al2O3Content is high, and network aperture is naturally just big in glass, is advantageous to
The diffusion of basic ion；On the other hand, volume increases, and is also beneficial to attract the K of large volume+Into acceleration ion exchange.Therefore
Al2O3Greatly improve the chemical tempering intensity of glass；Al simultaneously2O3Make glass that there is high chemical stability and excellent material
Mechanical property, it can effectively improve glass devitrification and water resistance；High-performance superelevation aluminium float glass Al2O3Content range is 17
~25%.
MgO can significantly reduce the high temperature viscosity of glass, improve the low temperature viscosity of glass, glass is easy in high temperature
Melting, is readily formed in low temperature.Magnesia is the conditioning agent that fluxing agent is also regulation material property in glass forming process；MgO contains
It is 1~4% to measure scope.
Na2O is fluxing agent, can reduce the high temperature viscosity and fusion temperature of glass, be easy to founding for glass；But Na2O's draws
Enter to reduce mechanical strength, chemical stability and heat endurance of glass etc., to control within the specific limits；The high property of the present invention
Na in energy superelevation aluminium float glass2O is introduced by soda ash, sodium chloride, sodium nitrate, and wherein sodium chloride, sodium nitrate add as fining agent
Enter, the Na introduced by sodium chloride and sodium nitrate2O amounts deficiency, insufficient section are introduced by soda ash, it is ensured that introduce Na2O total amounts are in glass
In mass percent be 13~15%.
Nd2O3, neodymium is added in silicate glass, and there is high-gain, high-quantum efficiency, low nonlinearity refractive index, low-loss system
Several characteristics, engineering properties is excellent, and has very strong impact resistance.Nd3+Ion makes struvite grid to radiation zone
Height and the width have an impact, improve glass radiation resistance.It is preferred that Nd2O3Content range is 0.5%~1.5%.
Sm2O3, add the appropriate Sm of people in glass, make glass that there is good shielding property；Because Sm absorbs ultraviolet
Visible ray, therefore Sm addition can be converted to, glassy lustre degree, light transmittance are good；For field of solar energy, light can be improved
