The Beryllium in the Emerald

In general, there is not only sound but also sparks will come out when metals collide with each other. Therefore, metal goods should not be used as much as possible to avoid the occurrence of collision and spark to cause danger in gas stations or the transportation of inflammable and explosive goods. But why do some metals collide without spark? And what kind of metal is it?

Many scientists study an emerald to see what magic it has. It was not until 1789, when the French chemist Vauquelin discovered the new element named “Beryllium” in the emerald, that the mystery of the millennium was solved.

Beryllium alloys with copper and nickel do not produce sparks when they collide with rocks or other metals. With the help of the special nature of beryllium alloys, people made specifically for the explosive mines, factories and oil base explosive area using a hammer and chisel, knife shovels, such as tool, which made a contribution to reduce the explosion and fire.

Beryllium is a light metal but very tough, the strength of which is stronger than steel. And its melting point 1285 ℃, which is much higher than magnesium and aluminum, both light metals. Beryllium content in the earth's crust is about 0.001%.

Beryllium, better known as the "jewel of the atomic energy industry", is a central source of a mixture of metal beryllium powder and radium salt that produces hundreds of thousands of neutrons per minute. These neutrons are used as projectiles to bombard the nucleus, splitting the nucleus and releasing huge amounts of energy, which is the atomic energy. In addition, it is necessary to slow down the generation of neutrons in order to achieve the goal of manual control of nuclear fission. Beryllium has a strong deceleration effect on fast neutrons, which acts as a moderator for nuclear reactors to keep the fission reactions going in an orderly and continuous manner.

Beryllium has many advantages as well as disadvantages, and that are many compounds of beryllium and beryllium are poisonous. Beryllium phosphate is formed in the body if beryllium salt in food is too high, which leads to soft bones and what is called beryllium chondrosis. Besides that, many of beryllium compounds can cause skin inflammation, pulmonary edema, and even suffocation.
