Sodium perchlorate is a perchlorate of sodium and has the formula NaClO4. Sodium perchlorate melts with decomposition at 480 °C (Lange's). Its heat of formation is -382.75 kJ mol-1. (NIST WebBook)
[edit] Uses
The present major use of perchlorate salts is as oxidizers in solid propellants. The potassium salt was first used and quickly followed by now most important salt - ammonium perchlorate. Lithium perchlorate, which has the highest weight percent oxygen, has been tested as an oxidizer in solid propellants, but has not found favor with propellant manufacturers.
