Appearance:Silver-gray powder
Density:7.14 g/cm3
Melting Point:1900 °C
Boiling Point:2642 °C
Flash Point:50 °F
Water Solubility:Insoluble in water.
Storage Conditions:Storage temperature: no restrictions.
Vapor Pressure:0 mmHg (approx)
Toxicity:Not reported-Rat LD50: 27.5 mg/kg
Flammability characteristics:Non-combustible; toxic chromium-containing fumes are produced in the fire;
Explosive limit:Powder will explode spontaneously in air. ... May ignite or react violently with bromine pentafluoride.
Odor:Odorless
PH:Bivalent chromium compounds are basic; trivalent chromium compounds are amphoteric; hexavalent chromium compounds are acidic
Experimental Properties:Enthalpy of fusion: 403.9 J/g at the melting pt|Under strongly oxidizing conditions, may be converted to hexavalent state & occur as chromate anions|Electronegativity (Pauling Scale): 1.6; orbital electrons: (Ar)3d5-4s1; abundance (% of earth's crust): 2X10-2|Chromium is a mixture of four stable isotopes with mass numbers 50 (4.31%), 52 (83.76%), 53 (9.55%) and 54 (2.38%). Thermal neutron capture cross sections are 17, 0.8, 18 and 0.38 barns, respectively.|For more Other Experimental Properties (Complete) data for CHROMIUM, ELEMENTAL (9 total), please visit the HSDB record page.
Air and Water Reactions:May be pyrophoric, as dust. Insoluble in water.
Reactive Group:Metals, Elemental and Powder, Active
Reactivity Alerts:Pyrophoric
Reactivity Profile:CHROMIUM reacts violently with NH4NO3, N2O2, Li, NO, KClO3, SO2 (NTP, 1992). Metal dusts when suspended in atmospheres of carbon dioxide may ignite and explode.
Flammable Limits:Noncombustible Solid in bulk form, but finely divided dust burns rapidly if heated in a flame.
Physical Dangers:Dust explosion possible if in powder or granular form, mixed with air.
Corrosivity:The silver soldered stainless steel wire corroded more than the cobalt-chromium type, & released more nickel & chromium than did the cobalt-chromium wires.
Heat of Vaporization:81.7 kcal/mol (at the boiling point)
