強さ、特に曲げ強さが十分でない。The glass-ceramic used as a multilayer ceramic circuit board is a composite fired body containing alumina and borosilicate glass as main components. However, since this glass-ceramic is prone to cranking in the glass phase,
Mechanical strength, especially bending strength, is insufficient for large substrates such as computer CPUs.

よって解決することができる。The above-mentioned problem is a glass-ceramic composite fired body whose main components are alumina and borosilicate glass, and barium oxide, calcium oxide, yttrium oxide, etc. Solved by a composite fired body characterized by containing cristobalite precipitated with vanadium oxide, niobium oxide, magnesium oxide, cordierite, spodumene, forsterite, or steatite as a filler in a borosilicate glass phase. can do.

バライト結晶粒を含まない。In the alumina-silicate glass composite fired body, cristobalite does not precipitate using alumina as a core, so even when fine alumina particles are present, the amorphous glass phase does not contain cristobalite crystal grains.

ンクが発生する。According to the present invention, the composite fired body containing cristobalite precipitated with the filler as a nucleus in the glass phase stops when the crank hits the cristobalite crystal. When the amount of the core filler is less than 2% by weight based on the total amount, cristobalite precipitation is small and the strength improvement effect is small, and when it is more than 5% by weight, cristobalite crystals and silicate crystals are formed. The coefficient of thermal expansion with glass (room temperature to 300℃) is 50x 10-'/'c, respectively.
, 3X10-'/°C, the difference in thermal expansion cannot be ignored in the cooling process after firing, and this causes cranking.

粉末を充填材とすることができる。In the following example, cordierite powder was used as the filler, but barium oxide, calcium oxide, yttrium oxide, vanadium oxide, niobium oxide, magnesium Mide, spodumene, forsterite, or atheatite powder may also be used as the filler. I can do it.

比べて２０％高い値を示した。5 parts by weight of polyvinyl butyrate, 3 parts by weight of dibutyl phthalate, and 100 parts by weight of methyl ethyl ketone were added to 49 parts by weight of alumina powder, 49 parts by weight of silicate glass, and 1 part by weight of cordierite powder. Wet mixing was performed to produce a green sheet with a thickness Q of 3 mm. Ten sheets of this were laminated and fired in the atmosphere at 1000°C for 4 hours to create a glass-ceramic composite. This fired body had a bending strength of 300 MPa, which was 20% higher than that of the additive-free product.

視できなくなったためである。A glass-ceramic composite was produced using the same steps as in Example 1 using 47 parts by weight of alumina powder, 47 parts by weight of silicate glass powder, and 6 parts by weight of cordierite powder as main components. Cracks occurred in the fired product during the cooling process after firing. This is because so much cristobalite was precipitated with cordierite as a nucleus that the difference in thermal expansion between cristobalite and the amorphous glass matrix could no longer be ignored.
