Piezoelectricity and Minerals

Hey dear Hive friends, first of all I would like to welcome you all to my contribution and hope you had a day which was full of positive experiences! In this post I would like to talk about minerals and hope you can learn something new.

Here you can see pictures of the minerals schorl which is also known as black tourmaline as well as quartz and both have piezoelectric properties and I would like to go into more detail about this effect in this post. In one of my last posts, I have already discussed pyroelectricity, which describes an effect that can create electric fields with the help of temperature and minerals and who should be interested in this topic will find my contribution here. These two effects are closely linked and piezoelectric minerals generate electric charges with the help of pressure and the word originally comes from the Greek and is derived from the word piezein for press and it was already known at the beginning of the 19th century and was first scientifically proven and documented in 1880 by the two French brothers Jaques and Piere Curie. In minerals or other materials that have this ability, the load triggered by pressure causes the ions out of balance and on the surface creates an electrical voltage that can theoretically be intercepted with electrons and minerals that have this property are characterized by their chemical composition and other minerals are Topaz, Elbaite, Wulfenite or Uvite. At that time, it was quickly recognized how interesting this effect can be in different economic areas and was used for the production of sensors or quartz oscillates and over time more and more areas of application were discovered and now it is also used by the defense, pharmaceutical, automotive or the electronic industry and there are many areas of application and I find this effect extremely interesting.

Thank you very much for stopping by and I hope you could learn something new about minerals! I captured these pictures with my Camera Sony Alpha 6000 plus 55-210 mm lens!
