Materials that retain their strength at high temperatures are called "refractory".
Pure carbon compounds -- graphite, carbon fibers, but alas, not diamonds -- stay solid at incredibly high temperatures.
That is why carbon-fiber-reinforced-graphite (RCC) is used on the hottest part of the US Space Shuttle, the nosecone.
RCC retains its strength at 2000°C.
For other refractory insulators and refractory metals, see the links.

What type of cup keeps hot water hot the longest?
A double-walled insulated cup made of stainless steel or ceramic will keep hot water hot the longest due to its ability to retain heat and prevent heat loss. Vacuum-sealed tumblers are also effective in maintaining the temperature of hot drinks for an extended period of time.
Why is hot material not kept in desiccator?
Hot materials are not kept in a desiccator because the sudden cooling caused by placing a hot material in a desiccator can create a vacuum inside the desiccator, leading to potential implosion. Additionally, the hot material can release gases or vapors that may react with the desiccant or other substances present in the desiccator.
What cup keeps water hot for the longest?
A double-walled insulated stainless steel cup will keep water hot for the longest period of time, typically up to 6-12 hours. It is designed to reduce heat loss through its layers, providing better insulation compared to regular cups. Vacuum-sealed bottles or cups are also good options for keeping liquids hot for extended periods.
Are molecules in cool substances closer together than in hot substances?
Yes, in general, molecules in cool substances are closer together than in hot substances. As substances cool down, their molecules lose energy and move more slowly, causing them to come closer together and form a more compact arrangement. Conversely, in hot substances, molecules have more energy and move rapidly, leading to increased distance between them.
What material shows something is hot?
Material can show that something is hot if it changes color, gives off light, emits steam or smoke, feels warm or hot to the touch, or increases in temperature when measured with a thermometer.
What material keeps hot water hottest?
polystyrene
On which cup keeps liquid hot the longest styrofoam glass plastic or paper?
syrofoam
Which Insulation Keeps Water Hot or Cold the Longest?

The presence of -------------- in a thermos flask keeps the substances either hot or cold?
A vacuum is the answer.
What cup keeps the hot chocolate the warmest?
Metal Cups will keep it the Warmest, for the longest amount of time.
What coffee maker keeps the coffee hot the longest?
any with a heated base will keep it warm as long as you leave it on.
Why metal cups keep hot water hot the longest?
Because metal absorbs and conducts more heat then most other substances so it keeps it hot. Just like when you cook, you use metal pans because they conduct the most heat.
What type of cup keeps hot water hot the longest?
A double-walled insulated cup made of stainless steel or ceramic will keep hot water hot the longest due to its ability to retain heat and prevent heat loss. Vacuum-sealed tumblers are also effective in maintaining the temperature of hot drinks for an extended period of time.
Which type of material keeps the hot liquid hotter for longer paper or metal?
paper, as long as it doesnt ignite
Why is hot material not kept in desiccator?
Hot materials are not kept in a desiccator because the sudden cooling caused by placing a hot material in a desiccator can create a vacuum inside the desiccator, leading to potential implosion. Additionally, the hot material can release gases or vapors that may react with the desiccant or other substances present in the desiccator.
How long was the longest hot dog?
Believe it or not, the world's longest hot dog was 203.80 meters long!
What are the best insulation substances so I can make a hot tub cover?
Custom-made whirlpool hot tub cover keeps the water warm better than the ones in store because it is designed to keep it warm at all times. So, custom ones are the best insulation substances.
