          Common carbon black includes the industrial furnace black, channel black, cracking and high-temperature graphitized carbon black as well as acetylene black etc. Acetylene black is high performance carbon black. Acetylene is made from calcium carbide. After purified it is isolated from the air and cracked at high temperature and cooled down. Then acetylene black is obtained and collected.
