Abstract
<PICT:0429616/III/1> In the manufacture of porous silicon carbide for use as a packing in fractionating columns, a mixture containing a small amount of sawdust with as much as 97,5 per cent of amorphous silicon carbide known as "fire sand" is packed around a graphite core in an electric furnace. Around this layer is packed the usual mixture of coke, sand, sawdust and salt, and the charge is raised to a temperature approaching 2000 C. Crystals of large size are formed about the core, and may be crushed to pieces 3 having dimensions of from 1 to 3 inches for use in stills. In an alternative method, ordinary silicon carbide reduced to the size of grit is moistened with a binder, such as the residue obtained by evaporating sulphite cellulose lye, and moulded into spherical or other forms. The latter are heated in a sand-carbon mixture or in a reducing atmosphere to temperatures of 2000--2600 DEG C., and recrystallization of the silicon carbide is effected with the formation of large crystals. Specifications 366,605 and 393,283 are referred to.
