Improving properties of high volume fly ash binder by mechanical and chemical activation [PDF]

Tehnika, 2020
High volume fly ash (FA) binders are characterized by long setting times and low early strength. By applying mechanical and/or chemical activation methods, it is possible to increase the reactivity of FA and improve the properties of the binder.

Effect of Mechanical Activation and Carbon Coating on Electrochemistry of TiNb₂O₇ Anodes for Lithium-Ion Batteries

Batteries, 2022
TiNb2O7 anode material with a Wadsley–Roth crystallographic shear structure was prepared by solid-state synthesis at a relatively low temperature (1000 °C) and a short calcination time (4 h) using preliminary mechanical activation of the reagent mixture.
