Worldwide gamma ferric oxide shortage delays cassette tape production Production at National Audio Company, America’s largest cassette tape manufacturer, has slowed due to the shortage of materials.

But however its surface rusted, the compound iron(III) oxide appears red because it absorbs the blue and green wavelengths of the light spectrum while reflecting the red wavelengths.

Production is being threatened, however, by a worldwide shortage of gamma ferric oxide, the most common material used for magnetic recording. According to a letter from NAC to its customers, ...

Rust -- iron oxide -- is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. Despite this poor conductivity, an electron transferred to a ...
