Effect of ball to powder ratio on the mechanosynthesis of Re2C and its compressibility

A review of green methods used in starch–polyphenol interactions: physicochemical and digestion aspects

“…53 The milling efficiency normally depends on the mill type, type of material, and milling condition such as the grinding material's density, time of grinding, size and number of grinding balls, milling speed (RPM), medium, and balls to the material ratio. 143 The ball mills are quite flexible in their capacity; a lab-scale ball mill can process the sample in a few grams to hundred grams while the industrial or commercial ball mill has a capacity of a hundred tons. It comprises a hollow cylindrical chamber that rotates around a horizontal axis, providing the necessary mechanical force.…”

Mechanosynthesis of β-Cr2N using BN as the nitrogen source

“…The accumulated energy supplied for the planetary ball-mill ∆E vaccum to the powder mixtures during the milling is calculated with the mathematical model described by Burgio et al and Martinez-Garcia et al [43,46,49]. However, accumulated energy supplied ∆E vaccum equation can be simplified as a function of the experimentally controlled variables such as the density of the milling material (ρ b ), the speed of the ball mill main disk (W d ), the milling time (t), and the sample mass (m s ), Equation 1.…”

“…A chromium nitride milling-energy map was built using the ∆E vaccum and the experimental results from XRD, FTIR, and TGA. The map was set up as described by Martinez-Garcia et al [43,49].…”

“…Therefore, the search for new methodologies is of great importance. High-energy ball-milling has proven to be a powerful technique for obtaining materials such as nitrides, carbides, borides, intermetallic and metastable phases [37][38][39][40][41][42][43][44]. Ball-milling has advantages such as easy operation, easy to scale industrially, short processing times, and that it could produce nanostructured powders.…”

Mechanical Alloying of Immiscible Metallic Systems: Process, Microstructure, and Mechanism

“…The powders agglomerated again when the ball-to-powder weight ratio was increased to 15:1, as the high energy transferred to the particles and increased the milling temperature. Martinez-Garcia et al [77] reported that the mechanosynthesis of the complete reaction of Re 2 C was achieved in the Re-C powder mixture after milling for 800 min and a ball-to-powder weight ratio of 33:1, 200 min and the ratio of 115:1, and 30 min and the ratio of 230:1.…”
