I worked with an ultra-fine high purity (99% + MgO) specialty alumina
several years back that sintered to high density at 1300C. I thought
it was a Baikowski alumina, but it has been a while. The material was
rather pricy if I remember correctly. I work with aluminas quite
frequently so this sinterability is quite unique, but you just might be
able to find a decent nanopowder to work with. If I can remember
anymore details I will pass them your way.
