摘要：
Integration of ferroelectric tunable components into dielectric layers of low temperature co-fired ceramic (LTCC) systems enables the realization of more functional multilayer ceramic modules (MCMs) for telecommunication applications. A composition designed for the low temperature sintering of ferroelectric BST material has been developed based upon previous work. Small amount of manganese is introduced to modify the properties of ferroelectric BaSrTiO3 LTCC compositions. The effects of manganese on sintering behaviour, microstructure, relative permittivity, dissipation factor and tunability are studied. Manganese enhances the sintering of the BST due to an increase in the amount of oxygen vacancies and which yields an improvement in the electrical properties of BST. (c) 2005 Elsevier Ltd.
