& 34;Ball Milling and Spark Plasma Sintering of Cerium ... , In this study, cerium silicides were used as a surrogate material to investigate the feasibility of high-energy ball milling and Spark Plasma Sintering SPS for the production of uranium silicide. Ball milling was studied as a function of time and composition. Each milled composition was then sintered by pressureless and SPS techniques.
& 34;Mechanochemical Synthesis and Spark Plasma Sintering of ... , The cerium silicides, Ce5Si3, Ce3Si2, CeSi, CeSi2−y, and CeSi2−x, have been prepared from the elements by mechanochemical processing in a planetary ball mill. Preparation of the cerium silicide Ce5Si4 was unsuccessfully attempted and potential reasons for this are discussed. Temperature and pressure of the milling vial were monitored in situ to gain insight into the mechanochemical ...
Mechanochemical synthesis and spark plasma sintering of ... , Here we describe the preparation of the entire range of cerium silicides by high energy ball milling HEBM , which is a self-enclosed processing technique that can limit oxygen contamination and cerium or silicon loss.
Mechanochemical synthesis and spark plasma sintering of ... , The cerium silicides, Ce5Si3, Ce3Si2, CeSi, CeSi2−y, and CeSi2−x, have been prepared from the elements by mechanochemical processing in a planetary ball mill. Preparation of the cerium ...
Phase Stability of Intermetallic Compound Ce 3 Al in ... , The present article reports on high-energy ball milling of the intermetallic compound Ce 3 Al at room temperature. It has been found that non-equilibrium supersaturated Ce solid solution was formed during the milling. The solubility of aluminum was estimated as 5 to 13 at. pct from the peak shifts of the X-ray diffraction pattern.
Mechanochemical Synthesis of Cerium Monosulfide - Alanko ... , Cerium sulfides were prepared by high‐energy milling of cerium and sulfur. The reaction kinetics were observed by monitoring temperature and pressure in situ.For the first time, it is demonstrated that cerium monosulfide, which has historically been produced only at very high temperatures using both toxic and flammable gases, can be produced from a stoichiometric mixture of the elemental ...
A study on the synthesis and magnetic properties of the ... , The initial activation of the mixed powders was done by high energy ball milling, a known technique for preparing homogeneous nanopowders,,. A high energy planetary ball mill with a ball to powder weight ratio of 10:1, vial velocity of 300 rpm and a milling time of 10 h was used for this purpose.
CN103589311A - Preparation method of titanate-modified ... , The invention discloses a preparation method of a titanate-modified nano cerium oxide/polyurethane composite paint. According to the preparation method, nano cerium oxide is modified by utilizing a titanate coupling agent so as to prepare titanate-modified nano cerium oxide powder, and the titanate-modified nano cerium oxide/polyurethane composite paint is prepared by utilizing the titanate ...
US4749545A - Preparation of composites - Google Patents , This invention relates to metal matrix composites containing at least 40% v/v of a hard material such as SiC and a matrix of aluminium, magnesium or alloys of either. The invention also covers a...
SYNTHESIS OF NANO PARTICLES BALL MILLING METHOD , Ball milling can be used to make carbon nanotubes and boron nitride nanotubes. It is a preferred method for preparing metal oxide nano crystals like Cerium CeO2 and Zinc Oxide ZnO .
