Through the avenue of adjusting the thermal properties of BaO–MgO–Al₂O₃–SiO₂ (BMAS) glass-ceramic by changing the MgO/BaO ratio, a BMAS glass-ceramic with the MgO/BaO ratio of 1:2 has been obtained, which shows satisfactory softening and crystalline behavior. Then, this BMAS glass-ceramic is used to lower the sintering temperature of Al₂O₃ ceramic. After systematic research on the sintering and physical properties of BMAS /Al₂O₃ composite with different glass-ceramic content, we find that when the content of BMAS glass-ceramic is 50%, the composite presents adorable comprehensive properties: dielectric constant of 5.40 @ ~10 GHz, dielectric loss of 1.91 × 10^− 3 @ ~10 GHz and bending strength of 143 MPa, meeting the requirement of LTCC substrate material for microwave application.
