were petroleum coke, calcined coke and graphite having Tyler mesh sizes from -65 to +250 and in some cases, from -65 to +400. As the gas flow rate through a bed was increased from zero, the resis tivity remained constant at the relatively low value of the
Nitrogen‐fluidized beds of petroleum coke and graphite were heated by applying an a.c. voltage to electrodes submerged in the bed. Bed resistivities, calculated from the voltage and power input required to maintain a constant temperature, show a similar decrease in
Currently, there is no known commercially viable substitute for calcined petroleum coke in the fabriion and utilisation of anodes for aluminium smelters. It boasts a superior coination of electrical conductivity and resistance to chemical and physical degradation in the smelting pot, which contains lower levels of contaminants (i.e. ash).
27/6/2019· Electrical conductivity is the reciprocal quantity of resistivity. Conductivity is a measure of how well a material conducts an electric current. Electric conductivity may be represented by the Greek letter σ (sigma), κ (kappa), or γ (gamma).
core of which consists of petroleum coke, tar coke as a filler, coal tar as a binder. Graphite electrodes are characterized by low resistance, good electrical conductivity and thermal conductivity, high resistance to oxidation and thermal shock, high

Petroleum coke samples are original one and those heat-treated at 1860, 2100, 2300, 2600, and 2800C (abbreviated to PC, PC1860, PC2100, PC2300, PC2600, and PC2800). First couloic efficiency of petroleum coke varies depending on the heat-treatment .
coke) with low hydrogen content and good electrical conductivity. These properties along with the low metals and ash contents make calcined petroleum coke the most competitive material currently available for making carbon anodes for smelting of alumina to
Electrical grade magnesia, called EGM, powders are use as electrical insulation of heating elements. EGM powders have a good thermal conductivity but a high electrical resistivity at elevated temperature.
Petroleum coke is a by-product of the coker process that occurs in the oil industry. Also known as "green petroleum coke", calcined petroleum coke is very important to link the oil and metallurgical industries for multiple appliions. ''s experience in petroleum
Conductive Plastic/Polymer AdditivesIntroduction:Plastics and polymers are inherently low in thermal and electrical conductivity. For this reasonappliions that require conductive properties, which could also benefit from the use of polymercomponents because of their light weight, high strength/weight ratio, easy moldability, etc, cannottake advantage of this desirable material.
