Cesium metal
Rubidium is a silver-white light metal with element symbol
Rb. It is soft and waxy, and its chemical properties are more active
than potassium. It is easy to release electrons under the action of
light.
Rubidium plays a violent effect when it encounters water, generating
hydrogen and rubidium hydroxide. Easy to react with oxygen to generate
complex oxides. Because the reaction with water releases a lot of heat,
hydrogen can be burned immediately. Pure metal rubidium is usually
stored in sealed glass ampoules. Rubidium is widely used in energy,
electronics, special glass, medicine and other fields
The nature of rubidium is between the potassium above it and the cesium
below it. It is extremely lively. It loses its metallic luster
immediately in the air, is violently oxidized by oxygen, and can cause
rubidium to ignite spontaneously. The reaction with water is very
violent, and it will explode even if it comes into contact with ice
below -100°C.
The chemical reaction of rubidium is more intense than that of sodium
and potassium, and it is easily oxidized in the air.
Rubidium has a lower melting point and hardness than potassium, and its
chemical properties are more active. Rubidium explodes on the surface
when it encounters water and dissolves in water to form an alkaline
solution.
Rubidium easily releases electrons under the action of light, which can
be used to make photoelectric tubes.
application
Frequency, time standard
The development of artificial earth satellite launch systems,
navigation, launch vehicle navigation, missile systems, wireless
communications, television broadcasting, transceiver split radars,
global positioning systems (GPS) and other space technologies are
accurate in the long and short-term of the frequency and time reference
used The requirements for degree and stability are getting higher and
higher. Due to the long-term stability of the rubidium radiation
frequency, the resonance frequency of the 87Rb atom is determined by the
frequency standard as the reference frequency. The rubidium atomic
frequency standard used as a frequency standard and a time standard has
the characteristics of low drift, high stability, radiation resistance,
small size, light weight, and low power consumption. The highly accurate
rubidium atomic clock has a travel time error of less than 1 second in
3.7 million years.
energy
Taking advantage of the easy ionization of rubidium, a lot of research
work has been done at home and abroad in the application of ion
propulsion rockets, magnetic fluid power generation, thermionic
conversion power generation, etc., and some important developments have
been made.
Special glass
Special glasses containing rubidium are currently one of the main
markets for rubidium applications. Rubidium carbonate is often used as a
special additive for the production of these glasses, which can reduce
the conductivity of the glass, increase the stability and service life
of the glass, and so on. Special glasses containing rubidium have been
widely used in optical fiber communications and night vision devices.
electronic
Because rubidium atoms lose valence electrons very easily, the energy of
visible light is enough to ionize the atoms, and the surface releases
free electrons under the action of light electromagnetic radiation,
showing excellent photoelectric properties, electrical conductivity,
thermal conductivity and strong chemical activity, making them in many
There are very unique uses in the technical field. Usually rubidium
compounds and alloys are important materials for the manufacture of
photovoltaic cells, photoemission tubes, atomic clocks, television
cameras and photomultipliers, as well as necessary materials for
infrared technology, such as rubidium antimonide, rubidium telluride,
rubidium cesium antimony alloy and so on. The photoemission tube using
the rubidium-tellurium surface is often installed in different
electronic detection and activation devices, and still has high
sensitivity in a wide radiation spectrum [6].
Rubidium cesium antimony coatings are commonly used on the cathode of
photomultiplier tubes for radiation detection equipment, medical imaging
equipment, and night vision equipment. A series of automatic control can
be realized by using these photocells and photocells.
medicine
Rubidium chloride and several other rubidium salts are used as density
gradient media in the ultracentrifugation process of DNA and RNA;
radioactive rubidium can be used for blood flow radioactive tracing;
rubidium iodide is sometimes used instead of potassium iodide to treat
goiter; some rubidium salts It can be used as a sedative, anti-shock
preparation and epilepsy treatment after using arsenic-containing drugs.
other aspects
In addition to the above application fields, rubidium and its compounds
also have the following typical applications: rubidium and its alloys
with potassium, sodium, and cesium can be used as getters for trace
gases in vacuum tubes and to remove residual gases in high vacuum
systems. Degassing agent. Rubidium is used as a chemical tracer to trace
different kinds of production items. The decay of 87Rb to 86Sr has been
widely used to identify the age of rocks and minerals
