Effects Of Ballmilling Treatment On Physicochemical

Ball-milling disrupted the layered structure of the h-BN, resulting in significant increases of surface area. Ball-milling at 400 rpm gave the highest surface area of 412 m 2 g −1 while higher rotation speeds decreased the surface areas due to agglomeration. Moreover, ball-milling resulted in the emergence of amino- and hydroxyl groups on the surface which were observed by Fourier transform infrared …

Calculation Of Grinding Balls Surface Area And Volume

S — the surface area of the ball; π — PIconstant, a mathematical constant that is equal to the ratio of the circle’s circumference to its diameter. 3.14 isa commonly used value for PI; R- the radius of the ball. The volume of a grinding ball is determined by the formula: V=4/3*π*R 3, where: V- the volume of the ball
