Mechanochemical synthesis of PZT powders
(Elsevier B.V., 2003-03-25)
PZT ceramic powders were successfully prepared from the mixture of PbO, ZrO2 and TiO2 by mechanochemical synthesis in a planetary ball mill, under different milling conditions. Phase evolution during synthesis was monitored ...
Mechanochemical synthesis of yttrium manganite
(2013-03-05)
Yttrium manganite (YMnO3) is a multiferroic material, which means that it exhibits both ferromagnetic and ferroelectric properties, so making it interesting for a variety of technological applications. In this work, ...
Encapsulation and Stabilization of β-Carotene in Amaranth Matrices Obtained by Dry and Wet Assisted Ball Milling
(Springer, 2017-03)
Amaranth starchy fractions have recently awakened interest from the industry, mainly due to its potential functional characteristics. The encapsulating efficiencies of starch-enriched fraction (SEF) and native starch (NS) ...
Mechanochemical synthesis of CaTiO3 from CaCO3 - TiO2 mixture
(Trans Tech Publications Ltd, 2004-07-27)
The synthesis of calcium titanate, CaTiO3, was performed by mechanical activation and thermal treatment. Milling for up to 360 minutes in a planetary ball mill mechanically activated an equimolar mixture of CaCO 3 and TiO2 ...
High-impact wet-milling: Effects of steeping conditions on rice starch attributes
(Wiley VCH Verlag, 2016-11)
Planetary ball wet-milling of rice was evaluated in comparison with traditional wet-milling. The effect of alkali and surfactant concentrations on starch recovery and purity, crystallinity loss, pasting profile, and gel ...
On Ti-18Si-6B and Ti-7.5Si-22.5B powder alloys prepared by high-energy ball milling and sintering
(ABM, ABC, ABPol, 2012-12-01)
Recently, a new ternary phase was discovered in the Ti-Si-B system, located near the Ti6Si2B composition. The present study concerns the preparation of titanium alloys that contain such phase mixed with α-titanium and other ...
Effect of ball milling energy on rheological and thermal properties of amaranth flour
(2015)
Abstract: Pearled amaranth grains obtained by abrasive milling were processed by planetary ball milling to produce starch-enriched flours. The influence of milling energy on rheological and thermal behavior of starch-enriched ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Kluwer Academic Publ, 2004-08-01)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...
Evaluation of grinding methods for pellets preparation aiming at the analysis of plant materials by laser induced breakdown spectrometry
(ELSEVIER SCIENCE BV, 2011)
It has been demonstrated that laser induced breakdown spectrometry (LIBS) can be used as an alternative method for the determination of macro (P, K. Ca, Mg) and micronutrients (B, Fe, Cu, Mn, Zn) in pellets of plant ...
