Abstract: 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.

Abstract: Methods are provided for beneficially reusing a paint-saturated filter aid, such as paint-saturated alkaline earth metal carbonates, as a substitute in applications requiring virgin alkaline earth metal carbonates. The paint-saturated filter aid is prepared by re-milling paint-saturated filter aid to a predetermined size to produce re-milled particles suitable for reuse in a variety of applications, including flooring, concrete, and the like. Also provided are flooring materials including re-milled particles of a paint-saturated filter aid characterized by one or more of: a median particle size (D50) of about 1 to about 50 microns; less than about 5% of the re-milled particles being retained on a 200 mesh screen; or a top cut size (D90) of about 5 to about 300 microns.
