It is provided by the present invention to contain lithium alumina silicate glass, without containing quickly reduction glass ion exchange surface region
The boron and potassium composition of compression（Content is not higher than 0.1 mole of %）, and by introducing suitable divalent cation oxide and control
Low-level monovalent cation alkali metal oxide is made, the glass with high Vickers hardness number is obtained；The silicon of aluminium containing lithium is improved simultaneously
The low-temperature characteristics of sour glass, it is possible to reduce stress relaxation number in glass ion exchange process, to obtain high bearing stress；This
Outside, suitable divalent cation oxide can be improved glass and resist damage ability and high cracking resistance energy.
SiO in glass of the present invention2Predominantly glass shaping body, it is necessary to which one of ingredient constitutes the netted main knot of glass
Structure.The SiO of 58~68 moles of % containing concentration in glass2, enough SiO2Assign the preferable chemical stability of glass, mechanical performance and
Processability.But SiO2Melting temperature can excessively high be improved, especially in glass there are the aluminium oxide of high concentration under conditions of, SiO2
Concentration should be controlled in below about 68 moles %, preferably less than about 66 moles of %, more preferably less than about 64 moles of %；It is too low in glass
SiO2Concentration can cause the ageing-resistant performance of glass and surface mechanical performance to tend to deteriorate, and increase ultra-thin glass is in cold working and clearly
It is generated during washing and scratches probability.Therefore, SiO2Concentration should be controlled in greater than about 58 moles of %, preferably above about 60 moles of %, more
Preferably above about 62 moles of %.
Al in glass of the present invention2O3For one of required ingredient, belong to network intermediate composition, in high-alkalinity glass
In ingredient, most aluminium oxide tend to glass aluminum-oxygen tetrahedron, constitute the netted main structure of glass, steady to improve glass
Qualitative and mechanical performance.Al2O3Volume ratio oxygen-octahedron volume is big in glass for the aluminum-oxygen tetrahedron formed in glass,
Glass volume expands, and to reduce the density of glass, more glass provides interchange channel in ion exchange process, greatly carries
High glass compaction is at stress and is compressed into stress layer depth, but Al2O3Belong to pole refractory oxides, can quickly improve glass viscosity,
Glass clarifying homogenizing difficulty is caused to increase, Bubbles in Glass and platinum rhodium foreign matter defects count will sharply increase；Although lithia at
Glass melting point can quickly be reduced by dividing, but higher concentration makes glass liquidus temperature quickly improve, it is difficult to be molded.Therefore in glass
The Al of about 12 moles of %~18 mole % of middle concentration2O3, preferably from about 12 moles of %~17 mole %.
Li in glass of the present invention2O belongs to one of ion exchange ingredient, and the present invention is by the way that experimental results demonstrate exist containing lithium glass
In salt containing sodium fusion, at appropriate temperatures, Li in glass can be passed through+And Na+It exchanges, is quickly obtained high compression stress layer depth.This
Outside, Li2O can make glass viscosity characteristic rapid decrease, and especially reduction high temperature viscosity is apparent, is conducive to glass melting and clarification,
For the Al of glass middle and high concentration2O3Concentration provide possibility, the present invention in Li2O concentration is not less than about 4 moles of %, such as rubs less than 4
Your % concentration, Li in glass+And Na+Exchange capacity is insufficient, it is difficult to obtain high compression stress layer depth；But high concentration Li2O concentration glass
Glass, liquidus temperature are reduced with glass viscosity, to make glass become easy devitrification, while if glass have it is too low
Low-temperature characteristics, such as strain point temperature be below about 550 DEG C, in glass ion exchange process, stress relaxation phenomenon is more apparent,
It is difficult to obtain high bearing stress, therefore, Li in the present invention2O concentration is below about 8 moles of %, preferably from about 4 moles of %~6 mole %.
Na in glass2O is one of required ingredient, provides a large amount of free oxygen sources, is risen to glass silica network structure
Destruction substantially reduces the viscosity of glass, contributes to glass melting and clarification.The Na of higher concentration simultaneously2O is glass chemistry
Strengthening offer may.Therefore, Na in the present invention2O concentration is not less than about 7 moles of %.But Na2O excessive concentrations will make glass machinery
Performance and chemical stability deterioration, especially in high-alumina concentration and the silicate glasses of phosphorus containing components, Na2O is easier to incline
Hydrogen ion in Xiang Yushui is swapped out and dissolves in water, accelerates glass surface chemistry performance change；In ingredient containing lithium glass, glass

Concentration ensures glass K in glass surface in fused salt containing potassium+And Na+Na ion concentrations needed for exchanging, therefore Na in glass2O
Concentration preferably less than about 11 moles of %.
The present inventor's many experiments confirm to maintain higher K in glass2O concentration helps to obtain the depth of high compression stress layer
Degree, but this compressive stress layers may not occur ion exchange with sodium ion for potassium ion in fused salt and be formed, but it is high in the present invention
Compressive stress layers mainly pass through Li+And Na+It exchanges and is formed, K in glass of the invention2O concentration is less than 0.1 mole of %, mainly leads to
Cross the introducing of raw material impurity concentration.

Al2O3Concentration proportion reduces strain point of glass temperature and surface Vickers hardness, it is difficult to reach strain point temperature and be more than or equal to 550 DEG C
It is more than or equal to 600MPa with the Vickers hardness before reinforcing.
B2O3At Network former oxide is belonged to, the strain point temperature of glass is can obviously reduce, and in high temperature melting mistake
There are oxide volatilization phenomenon in journey, it is unfavorable for glass ingredient stabilization.Many experiments show for glass ion switching performance and
Speech, B2O3It is unfavorable for high-pressure glass stress under compression and high stress layer depth, therefore by B in the present invention2O3Concentration is less than 0.1 mole of %,
It is preferred that B2O3A concentration of 0 mole of %.
P in the present invention2O5Belong to glass former ingredient, with [PO4] tetrahedron is mutually interconnected into network, but P2O5It is formed
Network structure belongs to stratiform, and interlayer is connected with each other by Van der Waals force, therefore, P in glass2O5It is small with viscosity, chemical stability
Difference and the big effect of coefficient of thermal expansion.But experiments indicate that P2O5Concentration has exchanged rush to glass reinforced technical process intermediate ion
Into effect, play an important role to being quickly obtained higher compression stressor layers.Therefore by P in the present invention2O5Concentration be limited in 1 mole of %~
4 moles of %, preferably P2O5Concentration is between 1.5 moles of %~3.5 mole %.

Surface compression stress is in same level with MgO, particular, it is important that ZnO has enhancement stress layer depth in glass reinforced performance
There is improvement.MgO concentration is about 0.1 mole~8 moles % in glass of the present invention, and preferably MgO concentration is that 3 moles of %~8 are rubbed
You are %.ZnO concentration is about 0 mole of %~3 mole % in glass in the present invention, but excessively high ZnO concentration can lead to devitrification of glass in glass
Tendency obviously increases, therefore preferably ZnO concentration is about 0.5 mole of %~2 mole %.SrO concentration is about 0 to rub in glass in the present invention
You are %~3 mole %, and preferably SrO concentration is about 0 mole~2 moles %.
The control of divalent cation oxide RO contents is between 2.5 moles of %~11 mole % in the present invention, as concentration is higher than
11 moles of %, then high divalent cation oxide concentration will hinder the efficiency of ion exchange to obviously increase and glass liquid phase in glass
