First, physical properties Antimony brittle silver metal, the melting point of 903K, the boiling point of 1908K, a density of 6.68g / cm 3, it has two allotropes. Niobium is a good conductor of electricity and heat, but unlike ordinary metals, the conductivity and thermal conductivity of tantalum solids are inferior to those of their molten states. Unlike ordinary metals, it shrinks by heat and expands when exposed to cold. There are three allotropes in the cockroach: jaundice, black cockroaches and ash. Similar yellow phosphorus and antimony white, soluble in carbon disulfide, lively nature. The black scorpion structure is similar to black phosphorus and is less active. Ashes (ie, metal ruthenium) are bonded by metal bonds and have a metallic luster and a diamond lattice. Second, the chemical properties at room temperature in the water and air are relatively stable, and do not work with dilute acid, but can react with nitric acid, hot concentrated sulfuric acid, concentrated hydrochloric acid, aqua regia, etc.: 2Sb+6H 2 SO 4 (hot, concentrated) 2Sb+6HCl 锑 does not interact with NaOH.

At high temperatures, helium can react with oxygen, sulfur, halogen, etc.:
4Sb+3O 2 2Sb 2 O 3
2Sb+3S Sb 2 S 3
2Sb+3X 2 2SbX 3 (X stands for halogen, for F 2 , SbF 5 can also be formed)
It can form alloys and compounds with many metals, such as M 3 Sb type compounds (M is an alkali metal) with alkali metals, and combines with Group IIIA elements to form IIIA-VA semiconductor materials, such as gallium antimonide GaSb, aluminum telluride AlSb Wait.
