If we were to send a unmannedspaceship through the Sun. What material can survive?
A wide variety of materials might survive passing through the outer layer of the sun, but only if the spaceship is big enough, fast enough and has a thick enough sacrificial/ablative shell.
If the ship is slow, it doesn't really matter if the hull survives, most stuff inside would melt.
The solar core is much hotter and at a pretty high pressure. You'd expect that of the core of a nuclear fusion reactor that size.
- Typical melting point of steel: 1370 C
- Melting point of tungsten: 3400 C
- Temperature of photosphere: 6000 C
- Temperature of Sun's core: 15000000 C
- Pressure in Sun's core: 4000000000000 psi
