オキシビスタリウム(I) 化学特性,用途語,生産方法
物理的性質
Thallium monooxide is a black powder; orthorhombic crystals; hygroscopic; density 9.52g/cm3; melts at 596°C; vaporizes at about 1,080°C; soluble in water, alcohol and acids.
使用
In manufacture of glass of a high coefficient of refraction for optical purposes (thallium flint glass) and for artificial gems.
製造方法
Thallium oxide can be made by heating Tl metal in air or oxygen. The brown-black thallic oxide, Tl
2O
3 , that may also form begins to lose oxygen at about 100°C converting to thallium oxide, Tl
2O.
Thallium oxide also can be prepared by thermal dissociation of thallium hydroxide, TlOH or thallium carbonate, Tl
2CO
3 Thallium oxide dissolves in water forming thallous hydroxide, TlOH. It reacts with carbon dioxide to form thallous carbonate, Tl2CO3.
危険性
Toxic by ingestion.
