Oct 15, 2019#0183;#32;Highenergy ball milling is a promising approach to enhance the reactivity of mZVAl. In this study, taking nontoxic and biodegradable stearic acid (SA) as the process control agent (PCA), ball milled mZVAl (termed as mZVAl bm ) was prepared and employed to activate persulfate (PS) for the degradation of trichloroethylene (TCE).
The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for highspeed milling. Schematic view of motion of the ball and powder mixture.
Highenergy ball milling : mechanochemical processing of nanopowders Subject: Boca Raton [], CRC Press, 2010 Keywords: Signatur des Originals (Print): T 10 B 4029. Digitalisiert von der TIB, Hannover, 2011. Created Date: 4/7/2011 1:49:37 PM
Highenergy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to highenergy collisions from the balls. Highenergy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickelbase super alloys that cannot be made by conventional powder metallurgy methods.
