Metals: tantalum, rhenium, wolfram, osmium
Nonmetals: diamond, graphite
Compounds: hafnium carbide, hafnium boride, hafnium nitride, tantalum hafnium carbide, etc.
assuming it is its own melting point NOTHING which is why its a MELTING point
The melting point is the temperature which a material, element or mixture, changes from the solid to a liquid. Therefore, all liquids become solids above the melting point.
Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.

is the temperature if the stiffer mantle above or below its melting point
Titanium has a high melting point of 3135°F (1725°C). This melting point is approximately 400°F above the melting point of steel and approximately 2000°F above that of aluminum.
The melting point is the temperature which a material, element or mixture, changes from the solid to a liquid. Therefore, all liquids become solids above the melting point.
If the temperature is below the melting point, you know it is in the solid state. If the temperature is below the boiling point, and above the melting point, you know it is a liquid. If the temperature is above the boiling point, you know it is a gas, etc. (Note: melting point is the same as freezing point).

Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
I use Petroleum Jelly, (Vaseline) in my wax and it lowers the melting point a bit.
Heat it up to above 660.32 °C (melting point)
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
when we lower the melting point of of ice for example from 00C TO -20C, as the temperature is 00C that is above the new melting point of ice so ice get melt
H2O is water. The melting point of water is 0oC or 32oF
