密封材料;SEALING MATERIAL

摘要

一种密封材料，其容易将雷射光转换为热能，显示良好的流动性，且有助于低熔点化，其含有玻璃粉末54.9体积%~99.9体积%、耐火性填料粉末0体积%~45体积%、雷射吸收材0.1体积%~10体积%，且以下述氧化物换算的质量%表示而言，玻璃粉末含有Bi2O370%~90%、B2O32%~12%、ZnO 1%~15%、CuO+Fe2O30.2%~15%、MgO+CaO+SrO+BaO 0.1%~20%作为玻璃组成。; and the glass powder expressed in terms of the following oxides by mass% has 70%~90% of Bi2O3, 2%~12% of B2O3, 1%~15% of ZnO, 0.2%~15% of CuO+Fe2O3, and 0.1%~20% of MgO+CaO+SrO+BaO as a glass composition.
