Structural transformations of alumina by high energy ball

2011. 3. 3.  Room temperature, high energy ball milling was applied to various transition aluminas (γ, K, χ), producing thermodynamically stable α-alumina–a phenomenon that could otherwise be achieved only by high temperature (1100–1200 °C) heat treatment. The transformation proceeds in two steps.

Effect of high energy ball milling on compressibility and

2012. 5. 1.  In order to break strong agglomerates, as-received nanopowders were mechanically milled in a high-energy ball mill (8000D mixer/mill, SPEX) with a ball-to-powder weight ratio of 10:1 for 3–60 min. To avoid contamination during the ball milling process, alumina vial and balls were used.

Modeling High-Energy Ball Milling in the Alumina-Yttria

2002. 2. 1.  Experimental results from high-energy ball milling of alumina-yttria powder mixtures have been analyzed with models collected from the literature. Depending on the milling conditions, either there is formation of an intermediate phase in the alumina-yttria system (yttrium aluminum perovskite, YAP), or the sample becomes mostly amorphous.

Effect of high energy ball milling and low temperature

2021. 5. 1.  High energy ball milling is a process commonly employed for breaking the powder into a fine, sub-micron or nano-sized powder,thereby imparting strain in the powder. In high energy ball milling, balls collide with each other and with the walls of the container with high impact energies, crushing the powder in between.

Effects of Ball Milling and Sintering on Alumina and Alumina

2020. 10. 13.  Reduction of crystallite size during high-energy ball milling is independent of boron composition in the range of compositions that were investigated. The lattice parameters of the main alumina phase as a function of milling time did not follow the same trends shown in literature, indicating any impurities within the literature samples
