An anodic bondable low-temperature fired porcelain having high-strength and low-thermal-expansion, wherein a conductive ion during anodic bonding is an Li ion, containing a complex oxide having a composition represented by the following formula:(1&#x2212;)(&#x3b1;LiO-&#x3b2;MgO-&#x3b3;AlO-&#x3b4;SiO).BiO&#x2003;&#x2003;(1)where x represents a mass ratio of 0.01 to 0.1, and &#x3b1;, &#x3b2;, &#x3b3; and &#x3b4; have a molar ratio of 2 to 5:1 to 2:1 to 2:7 to 17.

Anodic bondable porcelain and composition for the porcelain

A low temperature sintering ceramic composition can be sintered at 850 to 1,000&#xb0; C., and the sintered ceramic has a low dielectric constant (9 or less at 16 Ghz or more) and a high Qf (10,000 or more). The composition can be co-sintered with wiring material containing Ag, Au, or Cu. The ceramic composition includes (by mass) CaO, MgO, and SiOin total: over 60% to 98.6%; BiO: from 1% to under 35%; and LiO: from 0.4% to under 6%; wherein (CaO+MgO) and SiOare contained in the molar ratio of from 1:1 to under 1:2.5.

Low temperature sintering ceramic composition for high frequency, method of fabricating the same and electronic component

A low temperature sintering ceramic composition that can be sintered at a temperature equal to or less than 1000&#xb0; C. and has low dielectric constant and dielectric loss in a high frequency region of 17 Ghz or more, an electronic component using the same and a method of fabricating the low temperature sintering ceramic are provided. The composition comprises MgO and SiOin sum total in the range of from 64.0 to 99.2% by mass; BiOin the range of from 0.4 to 33.0% by mass; LiO in the range of from 0.4 to 3.0% by mass; and MgO and SiOare contained in the molar ratio of from 2:1 to 2:3.5, at least part thereof being contained as a complex oxide of Mg and Si.
