YBCO Yttrium Barium Copper Oxide Podcast Chemistry World
The story of yttrium barium copper oxide YBCO for short is the story of superconductivity which goes back over 100 years to 1911. YBCO is a superconductor at relatively high temperatures. By relatively high I mean around 93K which is still pretty chilly.
Yttrium barium copper oxide superconducting transition
The superconductors that fit in the BCS theory however have low T c which has greatly limited practical appli ions of superconductors. Lowtemperature superconductors such as NbTi and Nb 3 Sn can only generate magnetic fields up to 10.5 T and 20 T 33 due to their upper critical fields less than 25 T at 4.2 K.

Our superconductivity kit features a large superconductive disc formulated from the oxides of Yttrium Barium and Copper in the famous 123 chemical combination. The disc has a critical temperature of 92 degrees Kelvin. Chill the disc to 77 degrees Kelvin with liquid nitrogen and it produces a striking Meissner Effect magnetic levitation

A majority of superconducting wire manufacturers are migrating to new Second Generation 2G HTS materials utilizing Rare Earth BariumCopperOxide ReBCO compounds. 2G HTS materials are recognized as a superior superconductor by offering better performance in a magnetic field and improved mechanical properties all at lower cost.
How to Make a Superconductor at Home The Green Optimistic
Superconductors are known as the holy grail of energy transmission energy storage and even computing. You can make one yourself if you possess a bit of will knowledge and the following: Equipment. To make an yttriumbariumcopperoxide superconductor you will need: Yttrium Oxide Barium Carbonate TOXIC Cupric Oxide
Yttrium Barium Copper Oxides an overview ScienceDirect Topics
Preparation of the Ceramic Oxide Superconductors. The most common method of making the yttriumbariumcopper oxide superconductors is to mix dry powders of yttrium oxide barium carbonate and cupric oxide in the proper molecular ratios. Barium carbonate is used instead of barium oxide because commercially available barium oxide is very impure.
Superconductivity Making a High Tc Superconductor
The starting mix is a grey powder made by thoroughly mixing yttrium oxide barium carbonate and cuprix oxide in the ratios 1:2:3 This superconductor is often referred to as quot123quot as a result . Yttrium Oxide Y 2 O 3 11.29 grams. Barium Carbonate BaCO 3 39.47 grams. Cupric Oxide CuO 23.86 grams. 2.
