The ball mill machine was then operated at a speed of 300 rpm for 12 h and the rotation direction altered every 3 h. The resultant ball-milled biochars were labeled with BM, namely, BMHC450, BMHC600, BMBG450, and BMBG600. The N-doped biochar was prepared by ball milling 1.8 g biochar samples with 18 mL ammonium hydroxide (29%).
This study aimed to develop a facile synthesis procedure for heterogeneous catalysts based on organic guanidine derivatives superbases chemically grafted on silica-coated Fe3O4 magnetic nanoparticles.
A eutectic solution of ammonium nitrate and either aminoguanidine nitrate (AGN) or guanidine nitrate (AN) in the form of a pressed pellet is used to generate a low particulate non-toxic, odorless and colorless gas that is useful wherever an immediate source of such gas is required, such as the inflation of an occupant restraint air bag.
We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.
