A method is described for producing silicon particles, in particular for an anode material of a lithium cell. In order to improve the cycle stability of lithium cells and to minimize losses in capacitance, in particular, microorganisms are dispersed in at least one solvent in a method step a), the solvent including at least one silicon compound. In a method step b), the at least one solvent is then removed, and a residue remains. In method step c), the residue is then heated under a reducing atmosphere. In addition, the invention relates to corresponding silicon particles, and to a corresponding anode material including silicon particles, and to a lithium cell provided with such.

A ceramic composition for an injection-molding process for producing a combustion chamber pressure sensor, in particular for producing an insulation punch of a combustion chamber pressure sensor, includes a ceramic component in a proportion of greater than or equal to 50% by weight and a glass component in a proportion of less than or equal to 50% by weight. The ceramic component includes aluminum oxide. The glass component includes silicon dioxide or a silicon dioxide precursor. The ceramic composition further includes an alkaline earth metal oxide or an alkaline earth metal oxide precursor. The ceramic composition allows production of an insulation punch having a particularly good insulation capability. A ceramic injection-molding process includes the ceramic composition.
