Press Die for Ceramic Material

material ? size, general shape? more info

I would go look for some help from the American Ceramic Society (ACerS)

http://www.ceramics.org/

You will likely find publications on what your looking

Are you in the US?

Find out if there is a local ACerS chapter in your area and get in contact with them. They often have monthly technical meetings.

Are you wanting to green pack your shape in a hot press and then sinter in inert or vacuum atm. AcerS could also help you with phase diagrams for sintering temps and parameters.

I have a spark plasma sintering (SPS) furnace at our work that is used for consolidating difficult materials. We use it to sinter our cryomilled metallic and ceramic powders. These materials have a very fine nanocrystaline grain structure and would probably experience grain growth during heating and lose this super-fine grain structure during conventional sintering methods. Essentially the machine is a press that passes electric current though it much like a welder. The die material for this machine is generally always graphite.

Because your part is intricate, selective laser sintering could work rather well for low volume parts. Also Hot Isostatic Pressing, this is also a method we use with the nanocrystaline materials.

I hope that some of this helped you
