Antimony Definition, Facts, Symbol, Discovery, Property, Uses

What is Antimony. Antimony (pronunciation AN-te-MOH-nee) is a lustrous metallic element that belongs to the family of metalloids and is represented by the chemical symbol Sb [1, 2, 3]. There are two stable isotopes of antimony, including 121 Sb and 123 Sb with a natural abundance of

pressure of the roaster gas. Our circulating fluidized bed technology enables the necessary fine control over these parameters. To avoid losses in the leaching plant, it is recommended that whole ores are treated with a gold-roasting step. Due to the low specific heat value of whole ore, it is generally necessary to add fuel to the reactor.

steel objects. If "steeled" iron is cold hammered it gains additional strength. Quenching hot metal in cold water makes the metal harder and more brittle. If quenched steel is reheated to about 700°C it loses some of the hardness but regains some flexibility. This process is called tempering. The hardness of steel weapons made them superior to bronze.
