Segregation of Carbon Paste in a Smelting Electrode [PDF]

IMA Journal of Applied Mathematics, 1989
Summary: An industrial problem concerning segregation in carbon paste is described. Billets of paste, which are a mixture of coke and pitch, are fed into a steel tube in a furnace, and the tube is lowered at a rate of about 0.75 m \(day^{-1}\). In the tube, the pitch is deformable, and the paste is essentially a very viscous two-phase particulate ...

Glassy carbon paste electrodes

Electrochemistry Communications, 2001
A new carbon composite electrode material, based on mixing glassy carbon (GC) microparticles with an organic pasting liquid is described. The resulting glassy carbon paste electrode (GCPE) combines the electrochemical properties of GC with the various advantages of composite electrodes. Glassy carbon pastes (GCPs) offer high electrochemical reactivity,
