A Breakthrough: Silicon Carbide (SiC) Internal Reinforcement of Bulk High Temperature Superconductors

Why is HTS not used?

HTS are brittle single ceramic crystals while LTS are durable metals. HTS breaks easily which stops superconductivity. The time honored way to strengthen materials is internal fiber reinforcement or ¨straw in bricks¨.

But HTS is made by first melting component powders at ≈ 1200°C, then cooling under oxygen to form a single crystal. Reinforcing material placed inside oxidizes at high temperatures, forming impurities which interupts crystal growth and provides secondary seeding sites. These weaken HTS crystal strength and hurt performance. HTS strenghtening has so far been limited to external reinforcement such as Packing in Tubes, Deposition on Substrates, or Stainless Steel Encasing.

A Solution


¨A simple, reliable and robust reinforcement method for the fabrication of (RE)–Ba–Cu–O bulk superconductors¨ Devendra K Namburi , Kaiyuan Huang , Wayne Lau, Yunhua Shi, Kysen G Palmer, Anthony R Dennis, David A Cardwell and John H Durrell, 30 March 2020, Superconductor Science and Technology, Volume 33, Number 5 (

Open Article

RESULT: 40% improvement in mechanical strengh with just three 100 μm diameter parallel SiC fibers in a 25mm diameter sample.

CONCEPT: Silicon in SiC fibers reacts at high temperatures with O2 creating a layer of inert SiO2 preventing further oxidation. This is similar to why aluminum (Al) can be used for foil, pots and pans because Al reacts with O2 forming an inert layer of Al2O3. It is also how chromium (Cr) makes steel stainless.
