Question

what is molten sodium chlroide and aluminium molten oxide

Answer 1

Molten Nacl :-Molten Salt is a rather dreadful name for an otherwise useful catagory of materials & processes. The term "Molten Salt" is self-descriptive; it is melted salt(s). Another common name is Fused Salt(s). The simplest example of a molten salt would be to heat sodium chloride ("table salt") to a red heat (greater than 801° C, or 1474° F)1 upon which it would melt into a liquid. This liquid is stable, has a heat capacity similar to water (by volume) and flows much like water does. The major differences are the obvious higher temperatures attainable in the molten salt state and when the salt solidifies (freezes) it contracts versus expanding like water. Thus, molten salt freezing in a pipe would not burst the pipe as water would.
