    Abstract: An induction furnace capable of operation at temperatures of over 3100° C. has a cooling assembly (60), which is selectively mounted to an upper end of the furnace wall (76). The cooling assembly includes a dome (62), which is actively cooled by cooling water coils (68). During the cool-down portion of a furnace run, cooling initially proceeds naturally, by conduction of heat away from the hot zone through a furnace insulation layer (58). Once the temperature within the furnace hot zone (20) reaches about 1500° C., a lifting mechanism (80), mounted to the dome, raises a cap (16) of the furnace slightly, allowing hot gases from the hot zone to mix with cooler gas in the dome. This speeds up cooling of the hot zone, reducing cool-down times significantly, without the need for encumbering the furnace itself with valves or other complex cooling mechanisms which have to be replaced periodically. The life of a graphite furnace susceptor (10) at the high operating temperature is increased by surrounding the susceptor with a barrier layer (40) of flexible graphite, which inhibits evaporation of the graphite. Additionally, witness disks (154), placed within the susceptor, provide an accurate temperature profile of the hot zone.

    Abstract: An activated carbon foam material with improved graphitizability is formed by including an oxidation promoting metal-containing additive into the carbon foam and subsequently heat treating the foam in a reactive atmosphere. The oxidation promoting metal-containing additive greatly improves the development of the carbon foam's ramified pore system resulting in a carbon foam with a much greater surface area. This inventive foam may be created by introducing the oxidation promoting metal by way of an oxidation catalyst during the polymerization of the phenolic resin or as a inorganic chemical activating agent to the formed phenolic resin. The foam is then heated in a reactive atmosphere to produce an activated foam with a surface area of from about 200 m2/g to about 3000 m2/g.

    Abstract translation: 通过在碳泡沫中包含含氧化促进金属的添加剂并随后在反应性气氛中对泡沫进行热处理，形成具有改善的石墨化性的活性炭泡沫材料。 含氧化促进金属的添加剂大大改善了碳泡沫的分枝孔体系的发展，导致具有更大表面积的碳泡沫。 本发明的泡沫体可以通过在酚醛树脂的聚合过程中通过氧化催化剂引入氧化促进金属或作为无机化学活化剂引入所形成的酚醛树脂中来产生。 然后将泡沫在反应性气氛中加热以产生表面积为约200m 2 / g至约3000m 2 / g的活化泡沫。
