Chromium is a hard, steel-gray, shiny, metal that breaks easily. It has a melting point of 1,900°C (3,450°F) and a boiling point of 2,642°C (4,788°F). The density is 7.1 grams per cubic centimeter. One important property is that chromium can be polished to a high shine.

Steel Converter Slag as a Raw Material for Precipitation of …

The dissolution of calcium from steel converter slag by using acetic acid as a solvent and the precipitation of pure calcium carbonate from the resulting solution were experimentally investigated. It was found that, while strong solutions of acetic acid dissolve most of the calcium from the slag, weak acetic acid solutions dissolve calcium selectively.
