Abstract

<abstract abstract-type="main" xml:lang="en" id="jace12255-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Using discrete, ultrafine alumina, highly dense transparent (71% real in‐line transmission, RIT, λ = 640 nm) ceramics were achieved with grain size as small as 260 nm using standard SPS sintering. We show that use of La³⁺ as a dopant greatly reduces sensitivity to the sintering temperatures. Transparent alumina were achieved in a large range of sintering temperatures, 1140°C &lt; <italic>T</italic> &lt; 1200°C, thus providing better reliability and flexibility into the fabrication of large sintered transparent ceramic bodies.</p> </abstract>
