Gallium used for integrated circuits and optoelectronic devices - The Periodic Elements NFT (GIVEAWAY)

Gallium used for integrated circuits and optoelectronic devices - The Periodic Elements NFT (GIVEAWAY)


Gallium is the chemical element with atomic number 31 and its symbol is Ga.

It is a rare, soft and silvery metal. Gallium is very fragile at room temperature and its melting point is 29.76 ° C, so it can melt if the temperature of the environment in which it is found is around 30 degrees or if held in the hand. It can be used in high temperature thermometers. It has one of the largest range in the liquid phase, as well as the ratio between boiling temperature and melting temperature which is the largest ever, more than 8 times if expressed in kelvins; it also has a very low vapor pressure at high temperature.

Before its discovery, most of gallium's properties had been predicted and described by Dmitry Mendeleev, who called the hypothetical new element eka-aluminum, based on his periodic table.

Gallium does not exist pure in nature and neither are there gallium compounds sufficiently abundant to constitute an extractive source. Hence, gallium is obtained from the traces present in bauxite, coal, jasper, germanite and sphalerite. Combustion of coal can concentrate gallium: some residual combustion dusts contain up to 1.5% gallium.

Applications of Gallium:

  • digital and analog integrated circuits and optoelectronic devices (LED diodes and laser diodes) are the most common application
  • realization of very bright mirrors because it adheres to glass and porcelain
  • semiconductors and production of solid state electronic components such as transistors
  • production of metal alloys: used as a component of low melting point alloys
  • construction of high temperature thermometers

The giveaway

After a series of elements with the same color, the new element uses a color used only one other time until now: from aluminum. For those who have recently started following the collection, an article was written some time ago on the meaning of colors.

90 NFTs are dedicated to this giveaway (one user - one address):

  • 30 to the fastest to comment on the article with their WAX address
  • 60 to be assigned with extraction among all the others who will comment with their WAX address by January 24 at 16:00 CEST

We also remember the article published yesterday with some updates, where important information was given on the next giveaways.

The Periodic Table NFT project

The Periodic Table NFT project aims to raise awareness of chemical elements in a modern key, basing the approach on blockchain and Non Fungible Token.
Day after day it will be possible to know the single elements that make up the table, to collect curiosities about each of them and about the table in general.
We are working to be able to learn, in a playful way, also what happens by combining the various elements.
The whole project is based on the collection of NFTs that can be bought on the site https://wax.atomichub.io/market?collection_name=periodicelem&order=desc&sort=created&symbol=WAX or by participating in simple giveaways published on publish0x.

Periodic Table Of Elements - NFT
Periodic Table Of Elements - NFT

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. Each of us has a good memory of the school period. The periodic table of the elements was certainly a part of our journey. The time has come to retrace each element and collect the most exciting ones.
