Latest Patents

Hirschberg's latest patents include innovations related to Chlorofluoroferrate(II,III) and its manufacturing process. The process involves fusing alkali metal halides or ammonium halides with an iron(III) halide and metallic iron. The starting materials used in this process are specifically (a) an alkali metal chloride or ammonium chloride, (b) an alkali metal fluoride or ammonium fluoride, (c) anhydrous iron(III) chloride, and (d) iron powder. The reaction occurs at temperatures ranging from 300 to 900 degrees Celsius. The resulting chlorofluoroferrates exhibit significantly lower hygroscopicity compared to traditional chloroferrates, making them particularly suitable as active fillers for grinding wheels.

Another patent focuses on the use of non-toxic alkali metal chloroferrates (II,III) as replacements for toxic materials like lead chloride and antimony sulfide in grinding disks. This innovation not only enhances safety but also improves the overall performance of grinding disks.
