XLogP3:0.11250
Appearance:Clear colorless rod
Density:11.8 g/cm3
Melting Point:304 °C
Boiling Point:1473 °C
Flash Point:420°F
Water Solubility:Solubility in water: none
Storage Conditions:In the presence of water, a hydroxide is formed. Thallium is therefore stored under petroleum spirit, glycerine, or deaerated water. On prolonged storage under water with free access of air, metallic thallium becomes covered with large crystals of thallium(I) carbonate, and the water becomes saturated with this salt. To protect against oxidation, rods of thallium are coated with paraffin.
