Gball Mill Boron Carbide

is zirconia acceptable as milling media for ball milling,for ball milling it is necessary that the milling media is made of a material harder than the sample. but in the case of boron carbide it seems difficult to find a harder milling media..ball milling,vibratory milling and jet milling of boron,boron carbide powders with a average particle size of 23 6μm prepared by reducing boric acid with carbon in a carbon tube furnace was comminuted by ball milling,vibratory milling and jet milling respectively comminution efficiency,comminution mechanism and comminution kinetics of b 4c powder were studied the experimental results indicate that ball milling process has the minimal comminution.sintered high density boron carbide - norton company,270 grams of boron carbide having an average particle size of approximately 9 microns, and 30 grams of silicon carbide having an average particle size of approximately 2.5 microns were placed in an aluminum lined ball mill loaded with 0.5 inch diameter aluminum balls and 500 cc of isopropyl alcohol was added to the milling.the distribution of carbon in boron carbide: a carbon-13,substitution of silicon within the rhombohedral boron carbide (b 4 c) crystal lattice through high-energy ball-milling. journal of materials chemistry c 2015, 3 (44) , 11705-11716..
