Low-energy ball-milling (type – planetary, Company name – Insmart Kolkata, India) with a 3:1 ball to powder ratio was conducted at 150 rpm for 45 min to mix graphene in AlSi10Mg powder. The ball mill was kept idle for 10 min after every 15 min run to control heating.
Milling can be carried out in high-energy shaker mills (⁓20 g), relatively low-energy planetary ball mills (⁓250 g), or attritors (⁓1 kg). Industrial mills can process several kilograms of powder at a time. While large amounts of powder can be processed only at low speeds, small quantities can be …
high-energy mills. This former definition is not also adapted because the use of dry processing conflicts with examples of moist process of some materials [2]. A wider definition was proposed by Schwarz [3], for whom mechanical alloying is a high-energy ball mill technique employed to prepare powder alloys with unequal microstructure. On the
hBN was mechanically milled using Retsch CryoMill (Ball Mill). In each run, 3 g of the bulk hBN or 80 wt% bulk hBN/LLDPE (80%hBN) and 8 mm diameter steel balls (~2 g/ball) were loaded into a steel vial. The ball to powder ratio, the milling frequency, and the milling time were var-ied as required; however, at the optimum milling condi-
Synthesis of nanomaterials by a simple, low cost and in high yield has been a great challenge since the very early development of nanoscience.
