the organic binder constituents were degraded to carbon the resulting porous shaped body had a weight of 55 8 g and a porosity of 39 a carbonized shaped body as obtained in section 1 3and having a mass of 20 g was transferred to a graphite crucible coated with boron nitride covered with 22 g of a granulated fesi alloy consisting of 75 by weight of si and 25 by weight of fe and heated at 10 k min to 1550 u00b0 c under reduced pressure this temperature was held for 30 minutes and the crucible was then cooled to room temperature this procedure gave a dense crack and pore free shaped body having a density of 3 1 g cm 3 whose external geometric dimensions corresponded to those of the shaped body initially placed in the crucible instead of placing the shaped body directly in a graphite crucible 20 coated with boron nitride an alternative possibility is as shown in fig1 to use a porous sic charging plate 16 in the furnace chamber 12 of a reaction sintering furnace 10 this sic charging plate 16 stands on feet 18 in the melt 22 of the graphite crucible 20 coated with boron nitride or is connected therewith via porous wicks in this variant a larger amount of granulated material for producing the melt 22 can be introduced into the crucible 20 since the melt 22 rises from below through the porous feet 18 and the porous charging plate 16 into the shaped body 14 a green body was produced as described above by pan granulation.
