Silicon carbide (SiC) is produced from coke and quartz sand applying the Acheson process in an electric resistance furnace. When petrol coke and quartz sand are grouped around a graphite electrode and heated to a temperature of 2,000°C, black and slightly higher-quality green SiC are obtained. Green SiC has a slightly higher purity and hardness, but is also less tough.
