Compacted exfoliated natural graphite as heat conduction medium

Thermal-physical properties of the carbon-carbon materials on base of graphite foam

“…изкоплотные материалы на основе термо-расширенного графита обладают рядом важных технических качеств: высокими хими-ческой и термической стойкостью (выдержи-вают нагрев до 3000 °С в инертной атмосфере) и пористостью, простотой формования, позво-ляющей получать компакты с широким варьи-руемым интервалом теплопроводности [1][2][3], что определяет возможность их применения в различных сферах производства как в качестве высокотемпературной изоляции, так и в каче-стве теплораспределителя. В частности, такие материалы нашли применение в производстве теплораспределяющих панелей для потолочных систем обогрева и кондиционирования помеще-ний [4,5].…”

Electrochemical detection and removal of lead in water using poly(propylene imine) modified re-compressed exfoliated graphite electrodes

“…The EG particles were prepared according to a reported procedure [5,23]. In brief, NG flakes of particle size 300 lm, were intercalated with bisulphate anion for 24 h using a mixture of concentrated H 2 SO 4 and HNO 3 (3:1, v/v) under ambient conditions to form graphite intercalated compound (GIC).…”

“…Almost all heavy metals are toxic and excess levels are known to cause both acute and chronic health conditions [4]. Heavy metals cannot be degraded and the natural process of metal mineralisation is very slow [5]. Fundamentally, the removal of heavy metals from water and wastewater is best accomplished by immobilisation and concentration on suitable sorbents whereby the sorbed metals can be removed and reused as raw materials [4].…”

“…The harmful effect of Pb on child development can occur without clinical symptoms and might not present any abnormalities during routine testing. However, higher levels or prolonged exposure to Pb result in more severe symptoms such as kidney and nervous system damage [4][5][6]. These adverse health effects necessitated extensive attention in developing sensitive, reliable and rapid analytical methods [7].…”

Development and Validation of Graphitic Carbon Analysis of Graphite Ore Samples

“…The difference between the intensities of the forces in both directions is responsible for the anisotropic properties of the material [2]. Furthermore, due to the weak bonding between planes, the graphite crystals are very susceptible to disorder in this direction, which gives the material its softness and lubricity characteristics [3].…”
