In some embodiments, the ammonium sulfate is at least about 85 wt. % passable through a Tyler No. 48 sieve (0.30 mm opening). Ammonium sulfate subjected to commercial ball milling typically meets this criterion without additional screening. In some embodiments, the ammonium sulfate is about 99 wt. % passable through a Tyler No. 48 sieve.
