Millisecond photonic sintering of iron oxide doped alumina ceramic coatings.

The sintering of alumina (AlO) traditionally occurs at high temperatures (up to ca. 1700 °C) and in significantly long times (up to several hours), which are required for the consolidation of the material by diffusion processes. Here we investigate the photonic sintering of alumina particles using millisecond flash lamp irradiation with extreme heating rates up to 10 K/min.
