PbS Blue, metallic, cubic crystals that melt at 1120_C, derived from the mineral galena or by reacting hydrogen sulfide gas with a solution of lead nitrate; used in semiconductors and ceramics. Also known as plumbous sulfide.
Industry:Chemistry
CdS A compound with two forms: orange, insoluble in water, used as a pigment, and also known as orange cadmium; light yellow, hexagonal crystals, insoluble in water, and also known as cadmium yellow.
Industry:Chemistry
PbTe A crystalline solid that is very toxic if inhaled or ingested; melts at 902_C; used as a semiconductor and photoconductor in the form of single crystals.
Industry:Chemistry
UO<sub>2</sub> Black, highly toxic, spontaneously flammable, radioactive crystals; insoluble in water, soluble in nitric and sulfuric acids; melts at approximately 3000_C; used to pack nuclear fuel rods and in ceramics, pigments, and photographic chemicals. Also known as urania; uranic oxide; uranium oxide.
Industry:Chemistry
CdTe Brownish-black, cubic crystals with a melting point of 1090_C; soluble, with decomposition, in nitric acid; used for semiconductors.
Industry:Chemistry
Pb<sub>3</sub>O<sub>4</sub> A poisonous, bright-red powder, soluble in excess glacial acetic acid and dilute hydrochloric acid; used in medicine, in cement for special applications, in manufacture of colorless glass, and in ship paint. Also known as lead orthoplumbate; lead oxide red; red lead.
Industry:Chemistry
UF<sub>6</sub> Highly toxic, radioactive, corrosive, colorless crystals; soluble in carbon tetrachloride, fluorocarbons, and liquid halogens; it reacts vigorously with alcohol, water, ether, and most metals, and it sublimes; used to separate uranium isotopes in the gaseous-diffusion process.
Industry:Chemistry
Pb(SCN)<sub>2</sub> Yellow, monoclinic crystals, soluble in potassium thiocyanate and slightly soluble in water; used in the powder mixture that primes small arm cartridges, in dyes, and in safety matches.
Industry:Chemistry
Rb<sub>2</sub>SO<sub>4</sub> Colorless, water-soluble rhomboid crystals, melting at 1060_C; used as a cathartic.
Industry:Chemistry
UH<sub>3</sub> A highly toxic, gray to black powder that ignites spontaneously in air, and that conducts electricity; used for making powdered uranium metal, for hydrogen-isotope separation, and as a reducing agent.
