A surfactant-assisted high energy ball milling

2015-10-21  We herein exploit the advantages of surfactant assisted-high energy ball milling (SA-HEBM) for the processing of Mn–Al alloy. In this method, a combination of two surfactants, such as oleic acid and oleylamine, was used along with a solvent, n-heptane, during milling. The use of the SA-HEBM process yielded two different products: a sediment powder consisting of sub-micron sized Mn–Al flakes and a suspension in the milling

High energy ball milling process for nanomaterial

2021-3-8  Besides materials synthesis, high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions during milling (mechanochemistry).

2016-11-5  High- energy ball milling was carried out at room temperature using VQ-N Desktop high speed vibrating ball mill (Figure 1). One end of the principal axis of the mill connects with an eccentric wheel which is connected with the foundation of the ball mill through a tensile spring. When in operation the eccentric wheel swings at a high speed due to the tension of the spring. With the powerful vibration generated by the high speed swinging of the eccentric wheel, the ball milling jars fixed on the eccentric wheel rotate and vibrate at 1200 rpm. A zirconium oxide jar (Figure 2) was used with a stainless steel vacuum cover during the milling process in vacuum environment. Granularity of the material specimens placed in the jar was less than 1mm and the maximum material loading was two thirds of the cubage of the ball milling
