Sodium Beta Alumina Solid Electrolyte ?? (need sources)?
I've already asked this in the Engineering section a couple days ago. I was hoping a Materials engineer would know something. Now I'm counting on you chemists. 
I'm going to try my hand at building my own Sodium/Nickel Thermal Battery pack.
Only problem I'm running into is a source for Na-β″-alumina and/or it's precursors. I want it in powder or paste/slurry form so I can dictate it's final shape and sinter it myself.
Does anyone have any info on sources of Na-β″-alumina (ready for final processing), or info/sources for the precursors. (β-alumina, Aluminum Oxide, Sodium Oxide)
I've found numerous sources for Aluminum Oxide of questionable grade, 1 or 2 sources for β-alumina, but no sources for Sodium Oxide (NaO2) or Na-β″-alumina.
I will incorporate as a one-man-research-company if need be but I'd rather find sources that will sell to an individual in small bulk quantities. I only need a few dozen Kilos of the final product.
I can recommend MatWeb as a search engine for this sort of thing: http://www.matweb.com/index.asp?ckck=1 If you can't find what you're looking for, the site also has a forum for materials questions.
