Titania research Research from North Carolina State University indicates that a type of modified titania, or titanium dioxide, has potential as an electrical insulator for superconducting magnets, allowing heat to dissipate while preserving the electrical paths along which the current flows. According to NCSU, superconducting magnets are being investigated for use in next-generation power generating technologies and medical devices. “Superconductingmagnetsneed electrical insulators to ensure proper operation,” said Dr Sasha Ishmael, a postdoctoral researcher at NC State and lead author of a paper describing the work. “Changing the current inside the superconductor is important for many applications, but this change generates heat internally. The magnets will operate much more safely if the electrical insulators are able to shed any excess heat. Otherwise, the

higher temperatures could destroy the superconductor.

“This titania-basedmaterial is up to 20 times better at conducting heat than comparable electrical insulators,” Dr Ishmael said in a statement. “It has characteristics that are verypromisingforuseaselectricalinsulators for superconducting technologies.” The precise chemical composition of the modified titania is proprietary information The material’s development and characterisation was a joint effort between NC State and nGimat LLC, based in Lexington, Kentucky. The researchgroup’s findings arepublished in a paper. “Thermal conductivity and dielectric properties of a TiO 2 -based electrical insulator for use with high temperature superconductor-based magnets” is available online in the journal Superconductor Science and Technology.
