Above 1700 °C (1973 K / 3583 °F), diamond is converted to graphite. Melting point of graphite is 3700 to 4000 K. (It boils at around 5000 K)
It has been done by the Z-Machine at the Sandia National Laboratories by using a pressure of 10 million times normal Atmospheric pressure.

Will all lumps of pure iron always melt at the same temperature?
yes
What metal is not malleable at room temperature?
All metals melt at high temperature... the metal that doesn't melt is mercury as it is already liquid at room temperature..... There is no metal that undergoes sublimation unlike non-metals.
What metals are solid?
At room temperature, all metals except Mercury are solid.
Why can all three states of matter be seen in the same room?
It depends on the substance and not in temperature, we have gas (oxygen) we can have liquid (water, H2O) and we can have ice... that will melt
Do all metals melt at 1064 degrees C?
Samarium has a melting point of 1072 0C, near 1060.
Can you melt a coin?
Yes. You can melt almost all metals. You just need to find the melting point (which is the temperature at which the metal melts).
Do all substances melt at the same temperature as water?
no
What happens to metal at 200 degrees Celsius?
At 200 C:-- All metals become hot to the touch.-- The electrical resistivity of all metals becomes greater than at room temperature.-- The volume of all metals becomes greater than at room temperature.-- Some metals, but not all, melt (become liquid).
Do all materials melt at the same temperature?
No, materials do not melt at the same temperature. An example would be cooking oils. Some burn at lower temperatures than others.
Does everything melt and boil at the same time?
You could possibly arrange an experiment for different substances to melt and boil at the same time, but they would not do so at the same temperature. Different substances have different properties, they do not all melt and boil at the same temperature.
Will all lumps of pure iron always melt at the same temperature?
yes
What is an alkali metal which would melt?
All the alkali metals will melt.
Is metal made up of a liquid?
No, most metals are solid at room temperature, though they can all melt when heated enough.The only exception is mercury, which is liquid at room temperature.
What metal is not malleable at room temperature?
All metals melt at high temperature... the metal that doesn't melt is mercury as it is already liquid at room temperature..... There is no metal that undergoes sublimation unlike non-metals.
How does air turn into liquid?
Well you know how you get Ice and melt it into Water you do pretty much the same thing but with air.So all you have to do is melt the air and it turns into liquid.
State of most metals at room temperature?
It depends at what temperature. If we talk about room temperature then a natural state of a metal like Mercury is liquid (same as some non-metals like glass) while others like Copper are solid. Of course, in the vacuum of space where there is no influence of heat or sunlight, all metals are solid.
Does all metal melt?
yes all metals melt but at differenttemperatures some have low and some have high melting points
