无铅玻璃管，特别用于封装二极管和封装二极管的二极管

Lead-free glass tubing, especially for encapsulating diodes and diodes encapsulated with same
摘要：
The lead-free glass tubing of the SiO2—B2O3—R2O—BaO—ZnO—TiO2 system has a composition, in percent by weight on an oxide basis, consisting essentially of: SiO2, 34 to 52; B2O3, 10 to 25; Al2O3, 0 to 25; Li2O, 2 to 6; Na2O, 4 to 10; K2O, 2 to 6; CaO, 0 to 4; BaO, 1 to 5; ZnO, 4 to 12; TiO2, 2 to 6, and at least one refining agent in an effective amount for refining. An encapsulated diode consisting of a diode encapsulated with this lead-free glass tubing is also disclosed.
