Adsorption and morphology of oxidized starches on graphite
Minerals Engineering, 2021Hydrophobic gangue minerals such as talc, graphite and mica cause selectivity problems during flotation separation because they can be floated together with valuable minerals. This issue becomes increasingly prominent as the higher quality resources are depleted quickly.

Effects of morphology on properties of graphite composites
Carbon, 1989Abstract The relationship between the morphology of graphite fiber composites and their effective mechanical properties, thermal properties, and failure characteristics is demonstrated. Typical results are presented for studies at the fiber/matrix, lamina, and laminate levels of analysis.

Effects of Cu on the Morphology and Growth Mode of Graphite in Compacted Graphite Iron
Transactions of the Indian Institute of Metals, 2021In this article, Cu is found to have a great influence on the graphite morphology and growth mode in compacted graphite iron (CGI). Metallographic pictures show that the number of vermicular graphite of the surface of CGI casting is significantly higher than that of the core, and there is more spheroidal graphite in the core of casting.

Morphology and Electrochemical Performance in Graphite
2000The performance of a graphite electrode in a lithium-ion battery depends on a number of factors. The structure and morphology of graphite greatly influences the lithium intercalation process and is thus decisive in the selection of anode material [1]. It is also known that a decline in capacity on cycling graphite half-cells at high rates is due partly

Stable Eutectic—Graphite Morphologies
2018This chapter is entirely dedicated to the stable eutectic, that of austenite and graphite. This eutectic is abnormal due to the significant differences in both the proportions and the melting temperatures of each constituent. This last aspect will have an important influence on the structure and properties of the eutectic.

Graphite Growth Morphologies in Cast Iron
Materials Science Forum, 2014Graphite growth morphology was studied by using InLense detector on FEG-SEM after performing ion etching on the samples. Star like and circumferential growth mechanism of graphite was observed in the graphite nodules. Pure ternary alloy of hypo eutectic and hyper eutectic composition was treated with pure Mg, Ca and Sr, to study the effect of O and S ...

Morphology and electronic structure of graphitic sponges
Synthetic Metals, 1994Abstract Based on polyhedral packing in space, we demonstrate the new construction method for the structures of graphitic sponges expanding in three dimensional space because of the the introduction of 7- or 8-membered rings in a graphite sheet, which we propose to call “Pearcene”.

Graphite Morphology in Cast Irons
MRS Proceedings, 1984ABSTRACTGraphite structures formed during the cooling of molten cast irons and during their solidification were examined in alloys as a function of composition, treatment (magnesium and/or rare earths) and inoculation. The effect of cooling rate and solidification conditions on the morphology of the resultant graphite was investigated using a variety ...

Influence of the Graphite Morphology on Anion Intercalation
ECS Meeting Abstracts, 2016The redox-amphoteric character of graphitic carbon makes it possible to intercalate a broad range of anions and cations. These graphite intercalation compounds (GICs) are divided into two types: donor-type GICs, which host cations and acceptor-type GICs, which are formed by anions. A well-known application for a donor-type GIC is lithium-intercalated
