Effects of mechanical treatment on the formation of α-Al 2O3 from gibbsite
(Trans Tech Publications, 2004)
In this study preparation of fine alpha alumina powders derived from Bayer gibbsite was studied. Preparation of the alumina powders was performed by decomposition of the gibbsite into transition alumina phase followed by ...
Alumina/water suspensions in the presence of PEO-PPO-PEO triblock copolymers
The aim of this study was to investigate the stability and dispersion behaviour of aqueous alumina suspensions in the presence of polyethylene oxide-polypropylene oxide-polyethylene oxide (PEO-PPO-PEO) type triblock ...
A new methodology for removal of boron from water by coal and fly ash
High levels of boron concentrations in water present a serious problem for domestic and agriculture utilizations. The recent EU drinking water directive defines an upper limit of 1 mgB/I. In addition, most crops are sensitive ...
