The History of Graphite

The stories about graphite go back to about 1500 when an enormous deposit of graphite was discovered in the Borrowdale Parish in England. One of its first uses was as a refractory material to line molds for cannon balls, which resulted in rounder, smoother ammunition that could be fired farther.

Laboratory Graphitization Furnaces

Internal closed loop water cooling system which is installed inside furnace structure in a compact size and ideal for limited spaces in laboratories. Patented design of consumable materials of the hot zone in way that they can be easily replaced within 1 hour by a general trained operator.

Pyrolytic Graphite in the Design of a Compact Inert Heater

1970/4/1Pyrolytic graphite serves two functions in a new type of LaBSUB6/SUB cathode; it supports and heats the LaBSUB6/SUB emitter. The high anisotropic resistivity of pyrolytic graphite allows a compact heater-emitter design a few millimeters in size, and the chemical compatibility of graphite with LaBSUB6/SUB at the operating temperature of about 1500C prevents any lifetime

An Urgent Call to Spent LIB Recycling: Whys and Wherefores for Graphite

oriented pyrolytic graphite have been utilized so far to per-form the Li-intercalation experiments using electrochemical, vapor phase, and liquid intercalation methods that produce the graphite intercalation compounds like Li xC 6 (0 ≤ x ≤ 1). Inter-estingly, graphite

Investigation of the Differential Capacitance of Highly

A study of the differences among the capacitances of freshly exfoliated highly ordered pyrolytic graphite (HOPG, sample denoted FEG), HOPG aged in air (denoted AAG), and HOPG aged in an inert atmosphere (hereafter IAG) is presented in this work. The FEG is found to be more hydrophilic than AAG and IAG because the aqueous electrolyte contact angle (CA) increases from 61.7 to 72.5 and 81.8

Framatome HTGR

Framatome's Steam Cycle High-Temperature Gas-Cooled Reactor (SC-HTGR) is a small, modular, graphite-moderated and helium-cooled, high-temperature nuclear reactor with a nominal peak power of 625 MWt. The SC-HTGR is being developed for a wide variety of applications, including industrial process heat, hydrogen production, and moderate electricity generation.

High Thermal Performance Package with Anisotropic

The development of high power and compact size semiconductor packages lead to the challenge in the need of high thermal dissipation design. For package level thermal solution, metal (especially copper) heat spreader and metal/metal-oxide filler thermal interface material are widely adopted. However, the thermal performance of packages is limited by isotropic conductive behavior of most of

Nuclear Thermal Propulsion Reactor Materials

2019/10/9Nuclear thermal propulsion (NTP) systems have been studied in both the USA and the former Soviet Union since the 1950s for use in space science and exploration missions. NTP uses nuclear fission to heat hydrogen to very high temperatures in a short amount of time so that the hydrogen can provide thrust as it accelerates through an engine nozzle. Benefits of NTP systems compared to

Graphite Bonding Applications, Methods

Graphite Bonding Graphite is a relatively inert and stable material and is one of the allotropic forms of carbon. In plane, carbon atoms are bonded covalently while across atomic crystal planes there is a component of metallic joining where electrons are free to move along graphite's flat/hexagonal crystal planes leading to good electrical and thermal conductivity.

Plasma spray coating

Coating with alumina is very wear resistant, chemically inert and stable at medium temperatures, depending on the crystalline phase and deposition temperature. Other advantages are the elimination of arcing, very good non-stick properties of the coated surface and the inert layer acts as a separating layer between graphite and metal parts and prevents carburisation.
