Paper Abstract

Yttrium Iron Garnet (YIG) is an important material for high power infrared isolators as well as in microwave applications. When processed in bulk polycrystalline form, the transmission of this cubic material is greatly affected by non-stoichiometry and porosity content. This work investigates the effect of sintering additives, such as MgO, on the fabrication of YIG ceramics by way of conventional solid-state reactive (CSSR) sintering at 1380C for differing soak times. Specifically, we will be discussing the effect of these additives on the microstructure and densification kinetics and show that IR transparent bulk sized ceramics can be obtained with a grain size below 3 um.
