Description
Technical field
The present invention relates to AMOLED technical fields, and in particular to one kind is used for AMOLED high thermal stability alkali-free boron manosil ASs
Salt glass.
Background technology
The manufacture of AMLCD is extremely complex, and the property of base plate glass is particularly important.It is of prime importance that being used for
The glass substrate of production AMOLED devices must strictly control its physical size.Glass substrate must have following characteristic：Contain
There is alkali metal oxide to be less than l000ppm；Has chemical resistance；Thermal coefficient of expansion must be close with the silicon of thin film transistor (TFT)；Improve glass
Glass strain point, to reduce thermal shrinking quantity.
AMOLED glass substrate is according to the technical standard of liquid crystal display, it is necessary to possess following basic physics special
Property：1st, the thermal coefficient of expansion of glass substrate must be enough low, not higher than 40 × 10-7/ DEG C；2nd, the strain point temperature of glass substrate should
Higher than 640 DEG C；3rd, density is less than 2.6g/cm3, and more light better.
In order to obtain still alkali-free glass, using fining gases, produced when expelling glass reaction from glass melts
Gas, in addition when homogenizing fusing, it is necessary to reuse the fining gases of generation, increase alveolar layer footpath makes it float, thus taken
Go out the small bubble of participation.
But, the alkali-free glass as liquid crystal display glass substrate, the viscosity of glass melts is high, with containing alkali composition
Glass compare, need to be melted with higher temperature.In such a alkali-free glass substrate, generally cause glass in 1300-1500 degree
Change reaction, more than 1500 degree at a high temperature of deaeration, homogenize.Therefore, in fining agent, widely using can be in 1300-
1700 degree of temperature range produces the As2O3 of fining gases.But, As2O3 toxicity is very strong, glass manufacturing process or
During the processing of cullet, it is possible to the problem of polluting environment and bring health, it uses and is restricted.
The content of the invention
The present invention is intended to provide a kind of be used for AMOLED high thermal stability silicate glass containing boron and aluminium without alkali.
