摘要： In a known process for drawing a quartz glass strand, SiO2 particles are fed to a melting crucible and softened therein to form a quartz glass mass, and the softened quartz glass mass is pulled vertically downward as a quartz glass strand via a drawing nozzle which is provided in the bottom region of the melting crucible and has a gap-like drawing nozzle opening. In order, on the basis thereof, to make it easier to reproducibly produce a quartz glass strand with a minor deviation from the nominal wall thickness profile, and in particular to avoid irregularly occurring indentations and protrusions of the wall thickness profile, it is proposed according to the invention that the wall thickness profile of the quartz glass strand is detected, and that the drawing nozzle is heated by means of a plurality of heating elements which are distributed around the drawing nozzle opening and can be electrically actuated independently of one another, and that the quartz glass mass is locally heated by means of the heating elements within the gap-like drawing nozzle opening depending on measurement results of the wall thickness profile.

摘要： In a known drawing method for producing a cylindrical component from quartz glass, a quartz glass strand (2) is continuously drawn off from a softened quartz glass composition (13) vertically downwards in the drawing direction (3), a piece (15) with a weight G is detached from the free end of the strand at a time t1 and the cylindrical component is produced from the piece (15). When the piece (15) is detached, there may be a sudden reduction in weight, which leads to fluctuations in the thawing-off control. To counteract this, it is proposed according to the invention that a weight compensating force which acts counter to the drawing direction (3), increases over time and completely or partially compensates for the weight G of the piece (15), is applied to the piece to be detached at a time t0 before t1.

摘要： For use as electrode material for a lithium battery, porous templates are impregnated with a carbon feedstock that can be graphitized. This frequently results in only a low thickness of the deposited, graphite-like layer, such that generally several such infiltration and carbonation processes must be carried out consecutively. In order to provide a cost-effective product which is made of porous carbon and has high porosity and a low surface, according to the invention a method comprises the following method steps: (a) preparing a porous carbon structure having a large specific surface, (b) infiltrating the carbon structure with a precursor substance for carbon that can be graphitized, (c) carbonizing the precursor substance to form the carbon product having a low specific surface, wherein preparing the carbon structure according to method step (a) comprises the following: (I) preparing a template containing pores, (II) infiltrating the pores of the template with a solution that contains a precursor of carbon that cannot be graphitized, (III) carbonizing the precursor forming the carbon structure having the first specific surface, and (IV) removing the template.
