Calcium cyanamide - Wikipedia

This process requires meticulous temperature control since the melting point of calcium cyanamide is only about 120°C lower than the boiling point of sodium chloride. In 1901, Ferdinand Eduard Polzeniusz patented a process that converts calcium carbide to calcium cyanamide in the presence of 10% calcium chloride at 700 °C. The advantage of lowering the reaction temperature by about 400 °C, however, must be weighed against the high amount of calcium
