RockMelt is built on open-source code—the chromium software created by Google and used for its own Chrome browser.
Unlike metals like iron, which rusts and corrodes dramatically, chromium remains stable after oxidation and subsequent burial.
The quality of the manganese ores, however, is low, and reserves of chromium are insufficient for the needs of the economy.
chromium is a very hard metal of about the same density as iron.
Another class of European colours—the purples—came from cobalt, chromium, tin, and calcium.
Well, if I don't see him, you let him know about the chromium.
Masses of chromium ore (chromite) were carried upward with the molten material.
It is the common source of nearly all the other compounds of chromium.
Oxide of chromium and chrome iron ore have been proposed as refractory crucible materials.
The chloride of chromium is again precipitated with carbonate of lime, and by ignition converted into chromate of lime.
chromium chro·mi·um (krō'mē-əm)
A lustrous hard metallic element, resistant to tarnish and corrosion and found primarily in chromite. It is used to harden steel alloys, in decorative platings, and as a pigment in glass. Atomic number 24; atomic weight 51.996; melting point 1,907°C; boiling point 2,671°C; specific gravity 7.18; valence 2, 3, 6.
A hard, shiny, steel-gray metallic element that is rust-resistant and does not tarnish easily. It is used to plate other metals, to harden steel, and to make stainless steel and other alloys. Atomic number 24; atomic weight 51.996; melting point 1,890°C; boiling point 2,482°C; specific gravity 7.18; valence 2, 3, 6. See Periodic Table.
