| 发明名称 | Glass ceramic composition and coil electronic component | ||
| 摘要 | A glass ceramic composition of the present invention includes a main component composed of a first glass, a second glass, Al2O3, and SiO2. The first glass is SiO2—K2O—B2O3 based glass. The second glass is MO—SiO2—Al2O3—B2O3 based glass (“M” is an alkaline-earth metal) and/or CaO—SiO2—Al2O3—ZnO—ZrO2—B2O3 based glass. In case that the total amount of the main component is 100 wt %, the main component contains the second glass of 12 to 30 wt %, the first and second glass of 40 to 56 wt % in total, and further Al2O3 of 7 to 18 wt %. | ||
