Heslop and Robinson's Inorganic Chemistry (my copy published in 1960) says that it will decompose on heating in a stream of hydrogen at 800°C. I'm not sure what the purpose of the hydrogen is. If it was simply to sweep away the carbon dioxide to prevent it recombining with the oxide, it seems an unnecessarily hazardous way of doing it! It conducts heat and electricity easily and exhibits the photoelectric effect (emission of electrons when exposed to light) to a marked degree. Molten sodium is an excellent heat-transfer fluid, and, because of this property, it has found use as coolant in liquid-metal fast breeder reactors .Your translation will be ready in ${seconds} seconds.

Why Na2CO3 does not decompose on heating? Sodium carbonate will not decompose in the presence of heat. This is because sodium is a very reactive metal, and hence forms very strong bond with the carbonate ion. In contrast, aluminium is not as reactive as sodium. Hence the bond by aluminium is weaker, and aluminium carbonate will decompose when heated.
