Rubidium silicate glasses

Compton and Purdy [16] refashioned the FID of the Pye Uni cam Modified moving wire detector by inserting a rubidium silicate glass bead above the flame and thus made its response specific and changed it into a nitrogen phosphorus detector.

Critical temperatures often follow a simple trend for systems of related compositions. The critical temperature of alkali silicate melts, for example, decreases in the order of increasing radius of the alkali ion present, such that lithium and sodium silicate melts clearly exhibit metastable immiscibility, while the existence of immiscibility in potassium silicate glasses has not been conclusively established. There is no evidence for the existence of phase separation in the rubidium or cesium silicate systems. 

VIOLET Potassium compounds other than silicates, phosphates and borates rubidium and cesium are similar. Color is masked by lithium and/or sodium, appears purple-red through cobalt glass and bluish-green glass.
