    • PROBLEM TO BE SOLVED: To provide transparent and insulative low melting point glass which is hardly yellowed by reaction with a silver electrode, is suitable for forming a dielectric layer, and has high visible light transmissivity.
      SOLUTION: The transparent and insulative low melting point glass contains, in percent by weight, 2-15 SiO
      2 , 20-35 B
      2 O
      3 , 1-7 Al
      2 O
      3 , 35-60 PbO, 10-25 BaO, and 0-3 at least one kind of alkaline earth selected from CaO, MgO and SrO and further as an essential component 0.1-0.5 CoO and 0.01-2 CeO
      2 , provided that CoO+CeO
      2 is 0.1-2 and CoO/CeO
      2 is 0.1-5, and it is characterized in that these components are pulverized in a dry pulverization process. Further the low melting glass is characterized in that the weight loss from 120°C to 500°C after the dry pulverization process is 0.25-1.2 wt%, in that the whole light transmittance in 25 μm thickness is ≥80%, and in that the linear transmittance is ≥70%.

    • 要解决的问题:提供透明和绝缘的低熔点玻璃,其通过与银电极的反应几乎不变黄,适于形成介电层,并且具有高的可见光透射率。

      解决方案:透明和绝缘低熔点玻璃以重量%计含有2-15 SiO 2 SBB,20-35 B SB 2 O 3 3-SO 3,35-60 PbO,10-25 BaO和0-3至少一种选自以下的碱土金属: CaO,MgO和SrO,进一步作为必要组分0.1-0.5CoO和0.01-2CeO 2 ,条件是CoO + CeO 2 为0.1-2,CoO / CeO 2 为0.1-5,其特征在于将这些组分在干式粉碎过程中粉碎。 此外,低熔点玻璃的特征在于,干粉碎工序后,从120℃到500℃的重量损失为0.25-1.2重量%,因为25μm厚度的整个透光率为≥80%,因此 线性透射率≥70%。 版权所有(C)2006,JPO&NCIPI
