无砷低铁荧光灯用玻璃
摘要：
本发明提供一种无砷低铁荧光灯用玻璃，其以重量百分比计，含有SiO 2 ：60-75％、Al 2 O 3 ：0.5-5.0％、Na 2 O+K 2 O：12.0-22.0％、CaO+MgO：4.0-20.0％、B 2 O 3 ：0.5-5.0％、CeO 2 ：0.2-0.5％、Fe 2 O 3 ：0.02-0.05％，该玻璃与普通荧光灯用钠钙玻璃性能接近，适合低气压放电灯的玻管及其它部件生产，其不含有砷，环保性好，并且玻璃中铁氧化物成分的含量低，光线透过率高、用其生产的荧光灯光效可提高2％。
摘要（英）：

The invention provides glass for arsenic-free low-iron fluorescent lamps, which comprises the following components in percentage by weight: 60 to 75 percent of SiO2, 0.5 to 5.0 percent of Al2O3, 12.0 to 22.0 percent of Na2O plus K2O, 4.0 to 20.0 percent of CaO plus MgO, 0.5 to 5.0 percent of B2O3, 0.2 to 0.5 percent of CeO2, and 0.02 to 0.05 percent of Fe2O3. The glass has the advantages of properties similar to soda-lime glass for common fluorescent lamps, suitability for the production of glass tubes and other components of low-pressure discharge lamps, no arsenic, good environment-protecting property, low content of iron oxides, high light transmittance and capability of improving the light efficiency of fluorescent lamps produced from the glass by 2 percent.
