Placed in a 50 ml stainless steel autoclave which was designed to permit heating up to 500° C. were 6.3 g of industrial melamine (product of Mitsui Toatsu Chemicals Inc., average particle size: 20 μm) and 6.5 g of cyanuric acid ("ICA-P", trade name; product of Shikoku Kasei Corp.; average particle size: 3.1 μm) which had been comminuted beforehand by the jet mill. The contents were gradually heated to 350 ° C. under mixing. The contents were then maintained at 350° C. under mixing for further 1 hour, whereby 12.2 g of melamine cyanurate were obtained. The yield, purity and average particle size were 98.3%, 99.6% and 18.4 μm.
