Introduction Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 C (3,375 F) and boils at 2,672 C (4,842 F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated protective coating for other metals.
A wide variety of refractories chromium options are available to you, such as other inorganic salts, chromium oxide. You can also choose from industrial grade, electron grade, and agriculture grade. As well as from stainless steel. There are 978 refractories chromium suppliers, mainly located in Asia.
7 Interesting Facts About Chromium Chromium is a metal element with element symbol Cr, atomic number 48 and density 8.65g / cm³. Chromium is a shiny blue-gray transition metal, soft and wear-resistant, tough and ductile, flammable and irritating. The melting point of chromium is 320.9 ℃, and its boiling point is between 765 ~ 767 []
A refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides of the following materials: silicon, aluminium, magnesium, calcium, and zirconium.
Chromite refractory belongs to neutral refractory. Chrome bricks are bricks that contain chromium hemitrioxide 30%. Such bricks are featured with acid and alkali slags resistance, and are used in the isolation layer, and nonferrous smelting furnaces, etc.
