Abstract

<abstract abstract-type="author" id="abs0005"> <title id="sect0005">Abstract</title> <sec> <p id="spar0005">Glass free Bi₄(SiO₄)₃ ceramic tapes were prepared by non-aqueous solvent based tape casting technique. A higher powder loading above 65 wt.% was achieved in a silicate system through a judicious selection of suitable dispersants and binder. The amount of dispersant was optimized at 1.0 wt.% based on viscosity and sedimentation analysis. The surface morphology and mechanical strength of the green tapes were investigated. The as-prepared green tape of thickness 70 μm has an average surface roughness of 320 nm and a tensile strength of 0.37 MPa. The microwave dielectric properties of the green tape (<italic>ɛ</italic>_r = 6.2 and tan<italic>δ</italic> = 0.0390) and sintered tape (<italic>ɛ</italic>_r = 13.3 and tan<italic>δ</italic> = 0.0007) were measured at 15 GHz by using SPDR technique.</p> </sec> </abstract>
