铟(Indium),化学符号:In,是银白色并略带淡蓝色的金属。铟的质地非常软,能用指甲刻痕,且具有延展性,可压成片。铟有微弱的放射性,天然铟有两种主要同位素,一种为稳定同位素113In,另一种为115In。铟的常见化合物及其性状如下:三氯化铟(In Cl3)—白色结晶;三氧化二铟(In2O3)—淡黄色结晶状粉末;氢氧化铟[In(OH)3]—白色粉末;硫酸铟[In2(SO4)3]—
Indium, the chemical symbol: In, is a silver-white and slightly bluish-colored metal. The texture of indium is very soft, it can be scored with nails, and has ductility, can be pressed into pieces. Indium has a weak radioactivity, there are two main natural indium isotopes, one for the stable isotope 113In, and the other for 115In. Common compounds of indium and their properties are as follows: InCl3-white crystal; In2O3-light yellow crystalline powder; indium hydroxide [In (OH) 3] -white powder; Indium [In2 (SO4) 3] -
