Caesium

About Caesium (Cs)

Symbol: Cs
Atomic Number: 55
Atomic Weight: 132.90545196
Element Category: Alkali metal
Caesium, also known as Caesium, is a soft, ductile, silvery‐gold alkali metal. It is liquid at room temperature, as gallium and mercury are. Caesium is the most electropositive and most alkaline element.
Caesium is used in power generation, electronics and chemistry. Applications of caesium and its compounds include petroleum exploration, atomic clocks, electricity generation and catalyst promotion, among others.
Given that caesium is very reactive, various compounds are produced. Caesium nitrate is employed in the manufacture of optical glass. Caesium chloride is used in photoelectric cells, optical instruments and electron tubes.

Stanford Advanced Materials (SAM) can now offer various caesium products, including:

Caesium Compounds:
