Step 2) pulverize ball milling: each raw material is ground into the particle diameter granule less than 1mm with pulverizer respectively, then by each raw material mix homogeneously, delivers to ball mill, be milled to the powder that particle diameter is more than 100 orders;
Step 3) prepares glass: be first placed in by corundum crucible in Si-Mo rod stove, it is warming up to 1300 DEG C with the speed of 15 DEG C/min, then by step 2) gained powder adds in corundum crucible, insulation reaction 60min, is then warming up to 1500 DEG C with the speed of 10 DEG C/min, insulation 30min, the vitreous humour melted is cast in graphite jig, proceeds to immediately after shaping in chamber type electric resistance furnace and anneal, annealing temperature 600 DEG C, then lower the temperature natural cooling, to obtain final product.
Preferably, the thickness of gained glass is 3.2mm.
The present invention obtains beneficial effect and specifically includes that present invention process simple possible, and material choice is reasonable, is suitable for large-scale industrial production; Glass prepared by the present invention improves sunlight transmittance and visible transmission ratio, reduces ultraviolet (uv) transmission ratio, is greatly improved the photoelectric transformation efficiency of solaode; Glass plate heat stability energy consumption prepared by the present invention, mechanical strength is high, not broken.
