RUBIDIUM PERCHLORATE Chemical Properties,Usage,Production

Chemical Properties

-4mesh with 99.9% purity; white, rhomb crystal(s); hygroscopic [STR93] [CRC10] [CER91]

Uses

A perchlorate oxidizing agent. Rubidium perchlorate as chosen because its precipitation provides an excellent separation from strontium and since it is also an accepted weighing form for rubidium.

Purification Methods

Crystallise the perchlorate from hot water (1.6mL/g) by cooling to 0o.
