AbstractBismuth-borate glass braze (Bi25) with low melting point was utilized to braze magnesium titanate ceramic (MTC) in this work. The interfacial reaction between MTC and bismuth-borate glass braze made a well brazing possible. First, the Zn atoms from the glass seam substituted Mg atoms from MTC forming the phase (Zn,Mg)(2)TiO4 of lamellar morphology, which reacted with [BiO6] (or [BiO3]) from glass seam and then generated Bi4Ti3O12 of granular and sheet-like morphologies. The Mg2+ deriving from the reactions above reacted with [SiO4] unit from glass seam and generated Mg(SiO3) of granular and stripe-like morphologies. The shear strength increased first and then decreased with the increase of brazing temperature constantly. It reached a maximum value of 72 MPa at 725 degrees C. The dielectric loss tangent of joints always tended to zero at high frequency, and the dielectric constant of joints brazed at 750 degrees C was closest to that of base MTC itself.
