ỨNG DỤNG
Electron microscope technology used for cell and tissue fixed agent and stain. Antioxidant. Chloric acid is changed, peroxide, high iodine acidification and other oxidation reaction catalyst. Spectral analysis. Used for unsaturated hydrocarbon oxidation system glycol etc organic synthesis catalyst, olefins and anthracene oxidation generating alcohols, manufacturing high purity osmium, also used for antioxidant. Biological available its dilute water liquid liquid do biological stain. In the electron microscope to observe the ultrastructure, usually by osmic acid after fixed technology, retaining tissue cells to produce good contrast. Is also making a variety of osmium compounds (osmic acid potassium osmic acid sodium chloride dioxide three osmium osmium six chloride osmic acid salt, etc.) of the raw material.
