Tungsten carbide chemical formula WC is a chemical compound specifically a carbide containing equal parts of tungsten and carbon atoms In its most basic form tungsten carbide is a fine gray powder but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery cutting tools abrasives armor piercing shells and jewellery

The ball milling was done in methanol; therefore absorption of oxygen from the air is negligible and the source of O 2 must come from the commercial boron itself which contains B 2 O 3 It has been reported that boron generally absorbs oxygen at room temperature and forms B 2 O 3 on the surface of the boron

Carbide ball nose end mill can mill tooling steel carbon steel alloy steel tool steel cast iron and general iron in high working temperature situation 2 It reduces the actual cutting radius the cutting power and the cutting torque which is more conducive to the spindle motor working in a better state 3

Boron carbide is a covalent material characterized by a high melting point relatively low density and high chemical resistance;Such properties are suitable for boron carbide applications in components resistant to abrasion in ball mills nozzles parts of machinery and equipment and as parts of antiballistic armor Due to the high neutron absorption cross section boron carbide is used

The exfoliation process was realized by employing a planetary ball mill strategy Detailed characterizations showed that the ball milling process not only induces thinner layers and small sizes but also introduces numerous defects into the boron carbide catalysts which is vital in metal free catalysis Furthermore the exfoliated boron carbide catalyst was applied in aerobic ODS system and

Boron carbide synthesis by carbothermic reduction Carbothermic reduction is the most widely used commercial production method for boron carbide Inexpensive raw materials relatively easy manufacturing process and scalability made carbothermic reduction suitable for large scale commercial production of coarse grained boron carbide This method involves the reduction of boron oxide with

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 microns were placed in an aluminum lined ball mill loaded with inch diameter aluminum balls and 500 cc of isopropyl alcohol was added to the milling jar Both the milling jar and the balls were composed of high purity
