The word "barium" is correct.
It is used in scientific contexts, particularly in chemistry and medicine, to refer to a chemical element with the symbol Ba.
Example: "Barium is often used in medical imaging to help visualize the gastrointestinal tract."
Alternatives: "Ba" or "Barium sulfate".
By contrast, Symetrix uses barium strontium titanate, a layered form of perovskite, because of the problems that semiconductor fabs have in processing lead.
This, they hope, will push capacitors to 50% of a battery's storage capacity.A different approach has been taken by EEStor, a Texan firm that has developed a capacitor it claims can store "very high" levels of energy using a special insulator called barium titanate rather than an electrolyte.
The company's choice of a second-generation material is YBCO (yttrium barium copper oxide).
Then a coat is applied of yttrium, barium and copper, the metallic elements of YBCO, today's HTS recipe of choice, along with impurities just nanometres (billionths of a metre) across.
(The one that attracted attention in 1987 was an oxide of yttrium, barium and copper).
The first high-temperature superconductors, known as BSCCO (barium strontium calcium copper oxide) materials, were powdery and brittle.
Such a particle, if produced in his apparatus, would cruise through a detector made of barium-phosphate glass and leave a trail of damage along the way.The path of a monopole would have a distinctive pattern lots of damage at the beginning of its journey and very little towards the end of it.
The barium-radium mixture is separated.
In 1986 the two men succeeded in achieving superconductivity in a recently developed barium-lanthanum-copper oxide at a temperature of 35 K (−238° C [−396° F]), 12 K higher than had previously been achieved.
A charge of V2O5, iron oxide, and aluminum is ignited with a barium-peroxide fuse or a magnesium ribbon.
By repeated beta decay, the barium-144 in turn is converted step by step to other fission products, lanthanum-144, cerium-144, praseodymium-144, and eventually relatively stable neodymium-144; and krypton-89 is similarly transformed to stable yttrium-89 by way of rubidium-89 and strontium-89.
