ABSTRACT:
The invention relates to a method of providing a flowable carbon material, in particular for filling hollow spaces for the purpose of heat-insulation. A method of that type is to be laid out in a manner such that it is possible to produce thereby distributable or flowable carbon materials, which are less contaminating, in particular, which develop less dust and may also be manipulated in a simpler manner, with the efforts from the standpoint of procedural technique involved to produce these products are to be, if at all, only insignificantly greater than the efforts required in regard to the above-mentioned products. To this end, it is suggested to impregnate with a binder material paper particles in platelet form having an average diameter of from 0.5 to 5 mm and an average thickness of from 0.01 to 1 mm and/or in strip form having an average length of from 5 to 30 mm, an average width of from 0.5 to 10 mm and an average thickness of from 0.01 to 1 mm, which include an ash content of from 0.005 to 5%, and to carbonize them through a temperature treatment such that they form a flowable heap material having a bulk weight of from 30 to 300 g/l, i.e. 66 to 660 pound/m.sup.3.
