resistance to high temperatures |
What makes some materials resistant to high temperatures (meaning they
don't break at high temperatures)? Why are some materials high
temperatute-proof?

It depends what you mean by break...
If you mean melt then it's down to the strength of the bonds between atoms
of the material...
http://www.seed.slb.com/qa2/FAQView.cfm?ID=1012
If you mean burn then it depends on the relative strength of the bonds
between atoms of the material compared to those between the material and say
oxygen.

Why is it the relative strength of the bonds between atoms of the
material compared to those between the material and oxygen? Also what
determines the strength of the bonds?

its rate of thermal conductivity .
The next atom is cooling the latter.

As I understand it that determines how much energy (eg heat) has to be
applied before material reacts chemically with the oxygen.
Also what determines the strength of the bonds?
No easy answer to that one..

and I never was good at chemistry.

Name one material that "breaks" at high temperature.
break
v, broke, broken, breaking, breaks
1. To cause to separate into pieces suddenly or violently; smash.
2.
a. To divide into pieces, as by bending or cutting: break crackers for a baby.
b. To separate into components or parts: broke the work into discrete tasks.
3. To snap off or detach: broke a twig from the tree.
4.
a. To fracture a bone of: I broke my leg.
b. To fracture (a bone): I broke my femur.
5. To crack without separating into pieces.
6.
a. To destroy the completeness of (a group of related items): broke the set
of books by giving some away.
b. To exchange for smaller monetary units: break a dollar.
7. To vary or disrupt the uniformity or continuity of: a plain that was
broken by low hills; caught the ball without breaking stride.

Graphite melts at 3700 C.
Hafnium carbide melts at 3890 C.
Whatever spew you propose must accommodate both.
