PURPOSE: A dielectric magnetic composite for a multi-layer substrate is provided to minimize the substrate size and to guarantee the high dielectric constant under the 900 °C. CONSTITUTION: The dielectric magnetic composite for a multi-layer substrate comprises isolated base material and ceramic damping material having densification temperature under 900 °C and dielectric constant of about 13 ¯ 20. The isolated base material has SiO2 having an isolating composite range of about 50 ¯ 60 wt%, Al2O3 about 15 ¯ 20 wt%, B2O3 about 5 ¯ 10 wt%, CaCO3 about 0 ¯ 19 wt%, BaCO3 about 0 ¯ 19 wt%, respectively. The ceramic damping material has Al2O3 having an isolating composite range of about 30 ¯ 60 wt%, BaTi3 about 10 ¯ 40 wt%.
