Important Applications
The hyperfine transition frequency of cesium-133 atoms is used to define the "second" in the International System of Units (SI), with an accuracy of less than 1 second for tens of millions of years. It is widely used in GPS, satellite communications and financial trading systems.
Cesium formate (CsCOOH) is a high-performance drilling fluid that can remain stable under high temperature and high pressure environments, improving the efficiency of deep well drilling.
Cesium is extremely sensitive to light and is the core material of photoelectric tubes, infrared detectors and night vision devices.
The radioactive isotope cesium-137 is used for cancer radiotherapy, while the stable isotope is used for biological tracer research.

Frequently Asked Questions
Cesium is an exceptionally soft, light golden metal with a Mohs hardness of just 0.2. It features a very low melting point of 28.5°C, meaning it can melt into liquid form during warm summer conditions.
Due to its highly reactive chemical nature, cesium rapidly oxidizes and spontaneously ignites when exposed to air. It also reacts violently with water to release hydrogen gas and cause explosions, necessitating storage in vacuum environments, inert gases, or mineral oil.
Discovered in 1860 by Robert Bunsen and Gustav Kirchhoff using spectral analysis, cesium was named after the Latin word "caesius" (meaning "sky blue") due to the distinctive bright blue lines in its emission spectrum.
The hyperfine transition frequency of cesium-133 atoms defines the standard unit of a "second" in the International System of Units (SI). Cesium atomic clocks are incredibly precise, losing less than 1 second over tens of millions of years, which supports GPS, satellite communications, and global financial networks.
In the petroleum industry, cesium formate (CsCOOH) serves as a high-performance drilling fluid stable under extreme temperatures and pressures. In medicine, the radioactive isotope cesium-137 is utilized for cancer radiotherapy, while stable isotopes are used as biological tracers.
Cesium makes up only about 3 parts per million of the Earth's crust. It is primarily extracted from the rare mineral pollucite, making the extraction process complex and the resulting metal expensive.
