## ultra high temperature resistant - ultra low thermal conductive material

hi everyone,

im looking for a material which has those specs i mentioned above in the title.

-high temperature resistant like 1200 C
-low thermal conductivity which could be used for thermal barrier

actually same properties as aerogel has.but aerogels weak point is its being so brittle.what i`m looking for , must be durable against pressure and impact just like polymers or metals.

do you know this kind of stuff or it has not been invented yet?
