I my trying to build and oven need materials to use for interior and exterior

Welcome!

 

Do you mean: an oven for food? That would be rather easy, for temperatures like 350°C.

 

About every ceramic fits, like brick for instance. Some ceramics split under heat cycles, and I can't help further with non-technical ceramics.

Almost too hot for aluminium, but steel would fit - it just needs to resist oxidation, hence be stainless. Maybe the colour will change over a long time at 350°C, I'm not too sure. Enamels too suffice to protect steel at that temperature but that would be too long to investigate.

 

The nasty details come when you define how you heat the oven.

With a flame, some parts will be much hotter, and there you need better materials.

Electrically, you need a good wire (pick the existing specialized materials) and an insulator (pick existing ones) and you may need to circulate the air - already less easy.

 

Or do you seek hotter temperatures for a different use?
