melting point of nickle
Nickel, like all metals, is composed of positive ions (protons) surrounded by a sea of delocalised electrons. The attraction of these particles causes a strong force of binding that requires considerable energy to break. This is why nickel and its alloys have high melting points and can withstand high temperatures.
A high melting point is important for many applications. For example, copper-nickel alloys are used for a wide range of industrial applications due to their superior strength and corrosion resistance. Moreover, a good understanding of the different melting points of these alloys can help engineers and scientists to develop more efficient processing technologies.
The melting point of a metal is the temperature at which it reaches equilibrium between a solid and a liquid. When a solid is heated, its particles vibrate more and more rapidly, until at some point the amplitude of vibration exceeds the attractive forces operating between the particles. At this point, the particles invade the space of their neighbours and disturb them. The melting point is then reached.
My invention relates to a new and simplified process for melting nickel containing carbon, whereby it may be melted more quickly and economically than heretofore and in a practically pure condition. This is achieved by dispensing with the use of crucibles, and by directly subjecting a column of nickel in granular form to white-hot fuel under excessive pressure. The resulting melted nickel is then drawn off or poured as desired.
