The carbohydrates are selected from monosaccharides consisting of dextrose, fructose, galactose, or from disaccharides: maltose, lactose, saccharose or cellobiose.
Patent RO-122908-B1 (RO)
Title: Process for obtaining carbon electrodes
Inventor: SHAO RICHARD LIICHANG
IPC: B29C47/36
Filed: 2003-03-12
Abstract: The invention relates to a process for obtaining carbon electrodes, which consists in combining a filling material, a pitch binder and the carbon fibers made of mesophase pitch or PAN with an average length of 4.23...82.55 mm, the fibers being in a quantity of 0.5...10 parts by weight based on 100 parts by weight of filling material, extruding, roasting and graphitizing the composition thus obtained.
