Criteria Mixed melting point

In addition to the use of a melting point determination as a criterion of purity, an equally valuable application is for the identification of oiganic compounds. If the melting point is known within one degree, the major proportion of possible substances is immediately eliminated from consideration. The study of the general chemical properties of the compound and a mixed melting point determination (Section 1,17) will largely establish the identity of the compound. 

The hot-spot linear power was determined in accordance with the criterion that no fuel should be higher than the melting temperature, even at 10% overpower. The fuel at the peak linear power of 24.2 kW/ft has a center temperature of 4928°F (the estimated melting point of the mixed oxide fuel). The ability of the fuel to operate under these conditions is dependent upon the formation of a central void in the hot-spot...
