THALLIUM
(Ti)
MATERIAL
OVERVIEW
Characteristics:
Bluish-white, lead-like solid. Oxidizes in air at room
temperature. Soluble in nitric and sulfuric acids.
Insoluble in water, but readily forms soluble
compounds when exposed to air or water.
Hazards:
Forms toxic compounds on contact with moisture. Keep
from contact with skin. Tolerance (as Tl) for soluble
salts, 0.1 mg/m3 of air.
