Useful:

• Uses: Sodium acetate trihydrate (SAT) serves as a versatile and efficient thermal energy storage material due to its favorable properties such as high energy storage density, low cost, and stability. ^[1]; SAT's supercooling property enables its use in thermal therapy applications, where controlled heat release over an extended period is required. ^[2]
• History and Development: Research on SAT dates back to 1866 when its melting point was determined. ^[1]
• Production Methods: SAT is synthesized through chemical processes involving the reaction of sodium hydroxide with acetic acid, followed by crystallization to obtain the trihydrate form. ^[2]
