  • Composite material
    Patent number: 11843112
    Abstract: A novel composite material which includes silicon and carbon, the amount of silicon being 1-80 wt.-% and at least 90 wt.-% of the composite material being in a density range between a lower density threshold value p*1 and an upper density threshold value p*2. The density threshold values have the following relation: ?*1,2=(1±?)·?, wherein ? is the mean density of the composite material and ±? is the variation range between the upper density threshold value ?*2 and the lower density threshold value ?*1, the amount of ? being <0.10.
    Type: Grant
    Filed: June 28, 2018
    Date of Patent: December 12, 2023
    Assignee: SGL CARBON SE
    Inventors: Johannes Roethinger, Christian Schreiner, Bernt Ketterer
