			Using [[refractory material]]s as base material for [[gemstone based mechanical metamaterial]]s that [[elasticity emulation\|emulate elasticity]] may give new kinds of rubber like elastic materials that can endure extreme heat (way beyond what high temperature silicones do).

	For the probe to be feasible it must be capable to continually rebuild its hull at sufficient pace and push it from the inside out with only a few sparse nanoscapic voids to work in. Also it must be capable of sucking in magma and filtering out of that chaotic mix of elements the useful ones for the refractive hull and nuclear fission power. Moving from magma into machine phase seems highly nontrivial.

-To do [[consistent design for external limiting factors]] other [[diamondoid]] materials like the carbides of the titanium vanadium and chromium group ([//en.wikipedia.org/wiki/Carbide interstitial carbides]) can be used for high temperature applications since they are [http://en.wikipedia.org/wiki/Refractory refractory].

-Stability of free or mutual or environmentally contacting passivated surfaces (that are possibly strained) will reduce the allowed temperatures well below the bulk material melting points though. Interstitial diffusion may too be a limiting factor.
