Summary: | The present disclosure provides a novel glass filler which has low permittivity and is suitable for mass production. A glass filler provided herein includes a glass composition which contains, by wt%, for example, 40≤SiO2≤60, 25≤B2O3≤45, 0<Al2O3≤18, 0<R2O≤5, 0≤RO≤12, and in which at least one among i) SiO2+B2O3≥80, SiO2+B2O3+Al2O3≤99.9, and ii) SiO2+B2O3≥78, SiO2+B2O3+Al2O3≤99.9, 0<RO<10 is satisfied. Another glass filler provided herein includes a glass composition that contains SiO2, B2O3, Al2O3, and R2O, which respectively have the same contents as above, and 3<RO<8, and in which SiO2+B2O3≥75 and SiO2+B2O3+Al2O3<97 are satisfied. However, R2O equals Li2O+Na2O+K2O, and RO equals MgO+CaO+SrO.
L'invention fournit une nouvelle charge de verre de faible constante diélectrique, et adaptée à une production de masse. Une charge de verre fournie par l'invention contient une composition de verre qui, en % en masse, contient à son tour, par exemple, 40≦SiO2≦60, 25≦B2O3≦45, 0<Al2O3≦18, 0<R2O≦5 et 0≦RO≦12, et est telle que i)SiO2+B2O3≧80 et SiO2+B2O3+Al2O3≦99,9 et/ou ii)SiO2+B2O3≧78, SiO2+B2O3+Al2O3≦99,9 et 0<RO<10, est réalisé. Une autre charge de verre fournie par l'invention contient une composition de verre qui contient à son tour SiO2, B2O3, Al2O3 ainsi que R2O dont les teneurs sont identiques à ci-dessus, et 3<RO<8, et est telle que SiO2+B2O3≧75 et SiO2+B2O3+Al2O3<97 sont réalisées. Cependant, R2O=Li2O+Na2O+K2O et RO=MgO+CaO+SrO, sont satisfaits.
本開示は、誘電率が低く、量産に適した新規なガラスフィラーを提供する。提供されるガラスフィラーは、重量%で表示して、例えば、40≦SiO2≦60、25≦B2O3≦45、0<Al2O3≦18、0<R2O≦5、0≦RO≦12を含み、i)SiO2+B2O3≧80、SiO2+B2O3+Al2O3≦99.9、ii)SiO2+B2O3≧78、SiO2+B2O3+Al2O3≦99.9、0<RO<10の少なくとも1つが成立するガラス組成物を含む。提供される別のガラスフィラーは、含有率が上記と同じ範囲のSiO2、B2O3、Al2O3、R2Oと3<RO<8とを含み、SiO2+B2O3≧75、SiO2+B2O3+Al2O3<97が成立するガラス組成物を含む。ただし、R2O=Li2O+Na2O+K2O、RO=MgO+CaO+SrOである。 |
