Phase composition and particle size distribution in Mg(Ti1-xSn x )O3 powders

Abstract

Magnesium titanate-based ceramic dielectrics (MgTiO3) has been recognized as a favourite material for antenna fabrication in the microwave frequency communications industry as well as for other electronic applications, such as chip capacitors, high-frequency capacitors, temperature compensating capacitors and dielectric resonators. Various compositions of MgTiO3-based ceramic dielectrics have been fabricated using different starting materials and preparation methods. The dielectric performance has also been reported. This paper is devoted to report the initial work on a series of new composition of Mg(Ti1-xSn x )O3 powders for x = 0 - 0.04 prepared from liquid mixing method using metals powders as the starting materials. The phase composition and the particle size distributions in the systems were analysed and discussed in this paper.
