Procedure

An aqueous melamine solution prepared by heating at 85° C. 100 liters of water and 2.52 kg (20 moles) of melamine and an aqueous cyanuric acid solution prepared by heating at 85° C. 100 liters of water and 2.58 kg of cyanuric acid were mixed. Melamine cyanurate precipitated by the neutralization reaction was collected by filtration, dried and finely ground by means of a fine grinding machine to obtain finely powdered melamine cyanurate.
