to the present invention sintering of activated carbon is made possible by the application of certain pressure a more specific example of the novel process is set forth as follows activated carbon granules cx0648 1 available from em science size 0 5 0 85 mm bet specific surface area 1400 m 2 g were washed with distilled water and dried at 70 u00b0 c for 24 hours a rod mill was used to grind the dried granules into fine powders the grinding process lasted about 15 minutes at room temperature a copper can with a design as illustrated in fig3 was used as the capsule the activated carbon powders were filled through the stems of the capsule which was sealed right after filling was finished the filled capsule was then degassed under vacuum for 12 hours at a temperature of 150 u00b0 c copper wool and porous alumina were used as a filter to avoid the carbon powder being drawn out after degassing the stem was sealed with argon weld and the package was ready for elevated temperature compression the hip technique was employed and carried out using an abb autoclave systems inc mini hiper with argon as the medium a temperature of 800 u00b0 c was used in order to consolidate the carbon powders while maintaining the large surface area and high porosity a low pressure range was used which specifically ranged from 3 ksi 21 mpa up to 25 ksi 172 mpa the holding time was one hour to ensure good consolidation the time scheme used is illustrated in fig4 after cooling to room temperature the capsule was cut open and the hockey puck like cac material was removed the monolithic cac material manufactured by this novel process can be characterized by any of several properties.
