Abstract: In a vacuum atmosphere glove-box system filled with dry nitrogen, over all compositions containing NH4NO3 mole fraction in NH4NO3 and the eutectic mixture of binary system acetamide + urea were accurately prepared by weighting. The phase diagram of NH4NO3 and the eutectic mixture of binary system acetamide + urea was constructed by different scanning calorimetry method. Two concepts, the window of room temperature molten salt (RTMS) and depth of RTMS, were given to represent the capability and property of RTMS. According to the phase diagram, the clear evidence for the formation of RTMS was obtained. The area of the window of RTMS is x(NH4NO3)=15%-40%; the depth of RTMS is 32 K.
