摘要
Processes for producing melamine octamolybdates having high thermal stability include a step of reacting molybdenum trioxide and melamine in an acidic aqueous system at a pH of less than or equal to about 4 to form a slurry of the melamine octamolybdate. The resulting melamine octamolybdate can be characterized by a decomposition onset temperature (or a temperature at a weight loss of 1%, or a temperature at a weight loss of 2%) on a thermogravimetric analysis curve of greater than 300° C., and is useful in polymer compositions as a smoke suppressant.
