Abstract
Para la produccion de cianamida cálcica mediante la reaccion de urea con un compuesto de calcio que contiene oxígeno, en cuando menos dos etapas, a) en una primera etapa de reaccion, los componentes de la reaccion se dejan reaccionar a temperaturas de 120 a 500 degree 8C, sometíendolos a concentracion y/o revolviéndolos, o bien mediante su aplicacion sobre una superficie caliente, hasta que se forma una materia solida, y, b) a continuacion, se calcina a temperaturas de 600 a 900 degree C la mezcla solida que se formo. Con esto se obtienen elevados rendimientos y elevados rendimientos de paso, de cianamida cálcica, sin que para esto resulte necesario un reacondicionamiento costoso del producto de la reaccion, después de la primera o de la segunda etapa.
