Abstract
Process for obtaining melamine from dicyandiamide at high temperature and under pressure in the presence of a mixture constituted by inert gases and added ammonia, for which purpose the gas mixture represents at least 6% by weight of the dicyandiamide, not being less than 20% by volume and not more than 60% by volume, the ammonia content.
