Cesium perchlorate is an inorganic chemical compound of cesium from the group of perchlorates .

Extraction and presentation

Cesium perchlorate can be obtained by thermal decomposition of cesium chlorate , the decomposition taking place in two parallel ways. Since cesium perchlorate is still stable at temperatures around the melting point of cesium chlorate, it accumulates together with cesium chloride during decomposition .

properties

Cesium perchlorate is a white solid that is poorly soluble in water. The compound crystallizes isostructurally to barium sulfate in the orthorhombic space group Pnma (space group no. 62) with the lattice constants a = 9.832 (1) Å, b = 6.009 (1) Å, c = 7.764 (2) Å. Template: room group / 62

solubility in water
Temperature (° C)	0	10	20th	30th	40	60	80	100
Solubility (g / 100 ml)	0.1	1.0	1.6	2.6	4.0	7.3	14.4	30.0

When heated, it begins to decompose from around 220 ° C, and at higher temperatures it completely decomposes to cesium chloride and oxygen.

use

Cesium perchlorate is used for special optical glasses.

It can also be used to make other chemical compounds such as chloroperchlorate .
