types of balls used in high energy ball milling
BALL-MILLING OF TiO2 AND ZrO2. The high-energy ball-milling induced the phase transitions for which, otherwise, high temperature or high pressure were necessary In addition, the milling was shown to be a simple method for the preparation of nanoparticl The nanometric sizes of particles, achieved by milling, accelerated solid-state reaction at high temperatur.

High-Energy Ball Milling - an overview ScienceDirect
High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.

Induced by High-Energy Ball-Milling
2019-7-4 High-energy ball-milling was used in several works to produce nano-LN. Spex Mixer Mill 8000 is one of the most commonly used ball mills for this purpose. In general, dry grinding with one ball with a diameter of around 1 cm was used in these processes with grinding times as long as 5–20 h [13,15,20–22] and even longer than 100 h [23].

Iron nanoparticles produced by high-energy ball
2007-5-9 High-energy ball milling was carried out at room temperature using a vibratory mill (SPEX 8000 mixer), which combines a back-and-forth shaking motion with lateral movements at a speed of 1,800 rpm. These movements describe a figure in the form of number 8. A stainless steel vial and hardened steel balls were used.
