Tape Casting of Al 2 0 3 , MgO, and MgAl 2 O 4 for the Manufacture of Multilayer Composites for Refractory Applications
Source abstract
Abstract
The ceramic multilayer technique, which is based on tape‐cast green sheets, has the potential to generate advanced composite materials. In this work, high‐purity refractory oxides like α‐alumina, magnesia, and magnesium aluminate spinel were used for tape casting and multilayer processing. Highly porous Al 2 O 3 and MgAl 2 O 4 tapes were obtained with 16–36% open porosity and pore sizes <10 μm. Subsequently, increasing the grain sizes up to 1 mm led to multimodal slurries that yielded casting tapes of 3–5 mm thickness. Multilayer composites of different combination were prepared from these tapes by lamination and cofiring.
