Refractory metals - Wikipedia

2019-5-14 · Because of their high melting point, refractory metal components are never fabried by casting. The process of powder metallurgy is used. Powders of the pure metal are compacted, heated using electric current, and further fabried by cold working with annealing steps. Refractory metals can be worked into wire, ingots, rebars, sheets or foil.

Q & A: Lowering of Melting Point | Department of …

How much is the melting point of ice depressed per mole of solute. With an organic compound that doesn''t dissociate into ions in water, you use, of course, just how many moles you introduced. For completely dissociating salts you need to double the nuer of moles (in the case of NaCl) or tripplie it in the case of CaCl2. So how much per mole.

How to calculate melting/boiling points at different

What is the melting point of metal? - Quora

The melting point of a metal is the temperature where the metal changes phase from solid to liquid. Pure metals have a distinct melting point that is related to the bond energy of the atoms of that metal when they are solid. Metal alloys or mixtures of two or more metals will have varying melting points depending on the composition.
