I06 CYANAMID MANUI^ACTURE, CHISJMISTRY AND USES 



a material extent. The product is decomposed by high tem- 

 peratures such as are produced in burning buildings. It will 

 be noted that a relatively small amount of oil (4.2 per cent.) 

 and carbon 13.25 per cent.) are present. The high tempera- 

 ture to which the free carbon is subjected in the electric 

 furnace renders it sufficiently graphitic to be difficulty com- 

 bustible. 



"The product is susceptible to damage to a material extent 

 by fire or water. The product does not readily take up water, 

 and is not a good conductor of heat. In case of fire it will, 

 therefore, probably be only partially damaged by the heat and 

 water. 



"The product is considered non-hazardous except in respect 

 to susceptibility to damage by fire and water." 



In the process of manufacture, the cans containing the crude 

 calcium cyanamide are withdrawn from the nitrifying ovens at 

 a temperature of more than 1,000° C, and are allowed to cool 

 in the open air, without noticeable injury to the calcium 

 cyanamide.
