By sight white crystal substance. Is compound of calcium with carbon.
The main raw materials for receiving acetylene.
Technical acetyleneides of calcium contains 75% of chemically pure carbide of calcium, the rest — impurity (not extinguished lime, an oxide of iron, magnesium, aluminum).
Interacts with water, also actively absorbs moisture from air, emitting at the same time acetylene.
Speed of decomposition of carbide of calcium depends on temperature and purity of water, granulation and purity of an atsetilenid of calcium. The they are higher, the quicker it decays. Also the pieces of acetyleneides of calcium, the better and quicker its decomposition less.
It is packed into special drums from roofing steel. It is stored in special cans, with a hermetic cover. Near the place of storage of the opened drums smoking, use of naked flame is forbidden.
It is applied:
Are often used as abrasive materials, refractory materials, semiconductor materials, absorbers of neutrons in nuclear reactors.
Also acetyleneides of calcium found application in the equipment for production of acetylene, calcium cyanamide (a prinagrevaniya with nitrogen), and for restoration of alkaline metals.
Purge of liquid cast iron powder in a stream of inert gas for the purpose of desulphuration of cast iron and improvement of its properties.
It is applied to an intensification of vagranochny process, decrease in contents are gray also metal temperature increase.
