Chromium dioxide CAS NO.12018-01-8

Chromium dioxide (CrO₂, CAS 12018-01-8) is a high-purity synthetic inorganic compound supplied as a fine black crystalline powder. It is a ferromagnetic material that exists in a rutile-type crystal structure. Historically, it was the preeminent material for magnetic recording media, most notably in high-quality audio and video cassette tapes. Today, its primary industrial applications are in magnetic tape manufacturing, as a magneto-optic recording medium, and in specialized magnetic pigments, with emerging research applications in catalysis, spintronics, and lithium-ion batteries.

1.MECHANISM OF ACTION

Chromium dioxide's functionality is derived from its intrinsic ferromagnetic and semiconducting properties. In magnetic recording, its high coercivity, remanence, and magnetic anisotropy allow for stable, high-density data storage. The material's uniaxial magnetic anisotropy is a result of its tetragonal crystal structure. In catalytic applications, it acts as a redox-active oxide, facilitating electron transfer in oxidation reactions. Its semiconducting nature, with a band gap of ~1.0 eV, enables its use in magneto-optical devices and as a functional component in composite electrodes for energy storage.

2.PRODUCT INDICATIONS

This product is intended for Industrial and Research Use Only. Its primary applications include:
  • Magnetic Media Manufacturing: Production of specialized magnetic tapes for data storage and archival purposes.

  • Functional Pigments: Component in magnetic inks, toners, and security printing applications.

  • Catalysis Research: Catalyst or catalyst support for oxidation reactions, including the selective oxidation of hydrocarbons.

  • Advanced Materials R&D: Precursor for synthesizing chromium-based compounds; active material in research for spintronics, electrode coatings, and magneto-optical devices.


  • 3.CLINICAL EFFICACY OF PRODUCT

Chromium dioxide itself is an industrial chemical and catalytic material, not a therapeutic agent. Therefore, it has no clinical efficacy. Its performance is measured by its technical specifications: magnetic properties (coercivity, saturation magnetization), particle size, and purity. In its primary application, its "efficacy" is demonstrated by providing superior signal-to-noise ratio, durability, and storage density in magnetic media, which was critical for the performance of professional-grade audio/video tapes. In R&D, its efficacy is evaluated based on its catalytic activity, electrochemical performance, or magnetic response in experimental systems.
