Yttrium is the chemical element with atomic number 39 and its symbol is Y.
It is a silvery-looking transition metal, is common in rare earth minerals and is never found in nature as a free element.
Curiously, many minerals containing rare earths and other elements not very common in nature are found concentrated in a quarry near Ytterby. In addition to yttrium, erbium, terbium and yttria are also named after this Swedish town.
Moon rock samples taken from the various Apollo missions show a relatively high yttrium content.
The most important uses of yttrium are LEDs and phosphors, particularly the red ones from the cathode ray tube once used in televisions. Yttrium is also used in the production of electrodes, electrolytes, electronic filters, lasers, superconductors, in various medical applications and as a trace element in various materials to improve their properties.
Some commercial spark plugs for internal combustion engines have electrodes made of metal alloys containing small quantities of yttrium oxide, due to its high melting point and its high electrical conductivity. This expedient results in a slower wear of the electrodes and consequently a slower increase in the interelectrode distance.
Contact with compounds of this element, considered dangerous, is rare for most people. Yttrium salts are suspected carcinogens and, since yttrium is not normally found in human tissues, the possible biological role of this element is unknown.
The maxi giveaways are starting to like each other.
The maxi giveaway of strontium has just ended and we want to organize a new one right away.
Also on this occasion we want to slightly modify the rules of quantity and time.
This time we have one item, Yttrium, with a max supply 149. Also this time for the maxi giveaway we have decided to declare 90% of the entire supply: 134 NFTs that will be assigned with an extraction among all users who will comment this article with their WAX address within March 14 at 16:00 CEST (one user - one wallet).
We remind you that today is day 11 and that auctions are underway to find your missing piece of the collection.
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.
