LEAD AND CARBON. 



Certain old chemistries mention the existence of a compound of lead 

 and carbon. No carbide of lead has been made as yet in the electric 

 furnace, and the same is true of tin, bismuth, and gold.

LITHIUM AND CARBON. 



This carbide has been but recently made. Its formula is Li2C2. LiCOs 

 -[-40, heated for ten minutes, using a current of 350 amp. and 50 volts, 

 will yield it, or with 950 amp. it may be made in four minutes. A higher 

 temperature than this current produces in the furnace either volatilizes or 

 decomposes this carbide. Li2C2 forms shining crystals, sp. gr. = 1.65 at 

 i8°C. Decomposed by moist air and water, C2H2 being formed. It is 

 easily broken up and is not so hard as glass. Burns in the cold in CI or 

 Fl, and by gentle heating in Br or I. Concentrated acids have little 

 effect upon it. In hot water the decomposition is quite violent.

MAGNESIUM AND CARBON. 



In Dammer's Anorg. Chem. it is stated that magnesium heated in 

 benzol vapors yields a dark mass of this composition, MgC2. No such 

 compound has been made in the electric furnace. The reference given 

 does not mention a definite compound of Mg and C.
