    • A low temperature sintering, low dielectric inorganic composition is a ternary inorganic composition comprising cordierite, quartz glass and lead borosilicate glass, wherein if the amounts of the cordierite, quartz glass and lead borosilicate glass are represented by X, Y and Z (wt %) respectively, the composition of the ternary system falls within the range encircled by the following four points (a) to (d) including the lines between each neighboring two points:(X=35; Y=0; Z=65) (a)(X=65; Y=0; Z=35) (b)(X=0; Y=65; Z=35) (c)(X=0; Y=35; Z=65) (d)The inorganic composition has a dielectric constant substantially lower than that of the conventional composition while maintaining high reliability such as an ability of being sintered at a low temperature, high insulation properties and high resistance to water as well as excellent mechanical properties such as strength. The composition can be used for producing multilayer ceramic wiring boards for mounting very high speed VLSI elements and contributes to an increase in the packaging density and the production of fast transmitting devices.
    • 低温烧结低介电无机组合物是包含堇青石,石英玻璃和硼硅酸铅玻璃的三元无机组合物,其中如果堇青石,石英玻璃和硼硅酸铅玻璃的量由X,Y和Z(重量%)表示, (X = 35; Y = 0; Z = 65)(a)中的三个点(a)〜(d)所包围的范围内, (X = 65; Y = 0; Z = 35)(b)(X = 0; Y = 65; Z = 35)(c)(X = 0; Y = 35; Z = 65)(d) 组合物的介电常数基本上低于常规组合物的介电常数,同时保持诸如在低温下烧结的能力,高绝缘性能和高耐水性等高可靠性以及优异的机械性能如强度。 该组合物可用于生产用于安装超高速VLSI元件的多层陶瓷布线板,并有助于增加封装密度和快速传输器件的生产。
