how to make and fire alumina ceramics at low temp
how to make and fire alumina ceramics at low temp
(OP)
I know this question is below the level of expertise on this site, but I have searched for hours (google and here), and not really found anything on the basics. If you could just give me the 1, 2, 3 of how to make an alumina ceramic in my oven (~1000 F), I would be most appreciative.
So far, I have found ground alumina used for abrasive air blasting, but I assume this won't work (too corse maybe).
Also, I have found calcined alumina:

Is this what I need? Then what? Add water (read that high concentration alumina is water insoluble?). Add some other chemical to lower the firing temperature? Throw it in the oven?
Sorry you guys, a lot of basic questions. Maybe you can point me to a good book on the subject. Any help is appreciated. This is to be used for a crude conductive heat plate, so impurities and such are fine (just so it maintains a high thermal conductivity).
Thank you much.

Buy the powder and mix it with something that will set up at the desired temp but it won't have the properties of pure Alumina.
You could try massive pressure but not in a home oven. You could try laser sintering but not at home.
Maybe a low melting metal binder such as lead or zinc. Watch out for safety hazards from fumes. Again not pure alumina.
