LANTHANUM AND CARBON. 



C2La has been made from lanthanum oxide and sugar-carbon. These 

 heated for ten minutes in the electric furnace under the action of a cur- 

 rent of 350 amp. and 50 volts combine to form yellow crystals, sp. gr. 

 5.02. This carbide is decomposed by water, yielding C2H2, CH4, C2H4, 

 and leaving a residue of fixed hydrocarbons. The carbide appears golden 

 yellow on a fresh fracture. It is attacked by the atmospheric moisture 

 Pettersson gives H2 and C2H2 as the decomposition products.
