    Abstract: The invention relates to a soft-magnetic powder coated with a silicon based coating, wherein the silicon based coating comprises at least one of the following fluorine containing compositions: a) a fluorine containing composition of formula (I) Si1-0,25aM1aO2-0,5bFb (I) wherein a is in the range of 0.015 to 0.52, b is in the range of 0.015 to 0.52, M1 is H, K, Rb, Cs or NR1 4, wherein each R1 is independently selected from the group consisting of H, C1-6 alkyl, phenyl and benzyl; or b) a fluorine containing composition of formula (II) Si1-0,75c M2cO2-0,5d Fd (II) wherein c is in the range of 0.005 to 0.17, d is in the range of 0.015 to 0.52, M2 is B or Al; or c) a fluorine containing composition of formula (III) Si1-1,25e PeO2-0,5f Ff (III) wherein e is in the range of 0.003 to 0.10, f is in the range of 0.015 to 0.52. The invention further relates to a process of coating the soft-magnetic powder, the use of such soft-magnetic powder and an electronic component including such soft-magnetic powder.

    Abstract: A process for the production of sheets of paper, board and cardboard is provided. The process comprises the addition of at least one cationic polymeric retention aid or a retention aid system comprising the at least one cationic polymeric retention aid to a paper stock, draining the paper stock on a wire with sheet formation, and drying of the sheets. An endo-.beta.-1,4-glucanase is metered in an amount of from 0.00001 to 0.01% by weight, based on the dry weight of the paper stock, into the paper stock before the addition of the at least one cationic polymeric retention aid or retention aid system. Sheets of paper, board or cardboard produced by this process.
