Beschreibung
Zusammenfassung:	The invention discloses borosilicate glass and a preparation method thereof, and relates to the field of glass. The borosilicate glass is prepared from 61%-64% of SiO2, 19%-21% of Al2O3, 0.1%-1.8% of B2O3, 1.1%-2% of ZrO2, 0.06% < = Fe2O3 < = 0.6%, 10%-15% of alkali metal oxide and 1%-4% of alkaline earth metal oxide. The borosilicate glass is relatively good in heat insulation property. And the stress layer has a high surface stress value and a large depth. And the film has lower reflectivity and higher scratch resistance. 本申请公开一种硼硅酸盐玻璃及其制备方法，涉及玻璃领域。硼硅酸盐玻璃包括：61％～64％的SiO2、19％～21％的Al2O3、0.1％～1.8％的B2O3、1.1％～2％的ZrO2、0.06％≤Fe2O3≤0.6％、10％～15％的碱金属氧化物以及1％～4％的碱土金属氧化物；该硼硅酸盐玻璃隔热性较好。表面应力值高、且深度较大的应力层。具备更低的反射率和更高的耐划伤性。
