爆炸性锑
爆炸性锑是锑元素的一种极度活跃的同素异形体。当它受到刮擦，或突然受热时，就会爆炸。[1][2][3][4][5][6]它于1855年首次被描述，[7][8]可通过电解三氯化锑的盐酸溶液制取。[1][2][3][4]爆炸性锑晶体的边界处常常会出现以卤素为主的杂质。当它爆炸时，平均每克爆炸性锑会释放24卡路里的能量。[9]

Another possible allotrope, known as explosive antimony, has been reported which is produced by electrolysis of antimony chloride, iodide or bromide and is believed to be in a strained amorphous state.

Explosive Antimony is only metastable and transforms into metallic antimony during mechanical stress and heating. Explosive Antimony is probably not an allotropic form, but a mixed polymer.

We are indebted to the investigations of Professor Cohen for a more striking example of a metastable metal, that of the " explosive " antimony. By passing an electric current through a solution of antimony chloride this metal may be deposited in the form of a thick metallic coating.

The energy released by this transition, is measured to be 24 cal per gram of amorphous Sb and is shown to be related to a variation of the mass density and of the conductivity behaviour of Sb going from one configuration to the other. A simple theoretical model is outlined which quite satisfactory gives the gross features of the free-energy diagram of the above transition, although more deep investigation is needed to account for the energy balance of it.
