calcium cyanamide

n.
A white or colorless crystalline solid, CaCN2, that is used as a fertilizer and weed killer and impairs ethanol metabolism in humans who are exposed to it. The presence of impurities can cause it to appear grayish-black.

calcium cyanamide

n
(Elements & Compounds) a white crystalline compound formed by heating calcium carbide with nitrogen. It is important in the fixation of nitrogen and can be hydrolysed to ammonia or used as a fertilizer. Formula: CaCN2
