Uses,—Uranium finds few commercial applications, although several possible uses have been suggested. For a time an impure form of the metal containing some carbide was used as a sparking medium for automatic cigar lighters. These have now been superseded by cerium alloys, which are more highly pyro-... 

Increase of surface area by mere mechanical comminution may sometimes lead to self-flammable products. Such is the case in the ball-milling of certain stainless steels and of misch metal (cerium alloy) under a hydrocarbon. The process leads to formation of minute flakes with the character of bronzing powders. Spontaneous ignition after removal of the liquid in the case of the stainless steels is due to the absence of a passivating protective layer upon the newly created surfaces.

Roberts and Lock (1957) measured the heat capacity between 1.5 and 20 K on four lanthanum-cerium alloys (5.0, 27.0, 37.6 and 78.9 at% Ce) and found anomalies which moved to lower temperatures with decreasing cerium content. NikuUn and Patrikeev (1971) studied the nuclear heat capacity of lanthanum-cerium alloys at low temperatures (0.08 to 0.18 K). Culbert and Edelstein (1974) examined several... 

Chnard (1967) used electrical resistivity measurements to study the -phase forming tendencies of cerium alloys between 300 and 1.5 K. The addition of 2 at% samarium to cerium resulted in a hysteresis loop in the temperature vs. resistivity curve between approximately 40 and 170 K. This was attributed to the formation of some aCe during thermal cycling. 

Figure 39 is a plot of lattice spacing data for the cerium-rich portion of the cerium-scandium system as reported by Gschneidner et al. (1962). The experimental details are given in section 2.2.2. They found the solubility limit for scandium in cerium to be 17.2 at% Sc at 450°C. The second phase present in alloys containing more than 17.2 at% Sc is hep scandium. They observed that cerium alloys that contain more than 18 at% Sc do not oxidize on exposure to the atmosphere at 23 C.
