IN279514: An improved process for the modification of semi-coke suitable for the production of high density high strength graphite product
Abstract
The invention provides an improved process for the modification of semi-coke suitable for the production of high density-high strength monolithic graphite. The properties such as density, strength and electrical resistivity are found to be superior from the pitch coated GC based graphite in comparison to graphite products without pitch coating. The bulk density of the high density product so produced by the process of the present invention is found to be in the range of 1.80-1.90 gcm-3, bending strength in the range of 600-1200 Kgcm-2 and electrical resistivity in the range of 1.0- 2.0 ohm metre.
