Superconductor Technologies Inc. Awarded Patent for Superconducting Material
Composition and Manufacturing Process
Strengthens Patent Portfolio for Conductus Superconducting Wire Technology
AUSTIN, Texas, May 7, 2014 (GLOBE NEWSWIRE) -- Superconductor Technologies
Inc. (Nasdaq:SCON) ("STI"), a world leader in the development and production
of high temperature superconducting (HTS) materials and associated
technologies, was awarded U.S. Patent No. 8,716,187, entitled
"RF-Properties-Optimized Compositions of (RE) Ba2Cu3O7-8 Thin Film
Superconductors" from the U.S. Patent and Trademark Office (USPTO). This
patent further enhances the company's intellectual property portfolio that
supports the Conductus^® superconducting wire program.
"Our proprietary RCE-CDR fabrication process and material composition of ReBCO
provides critical cost, performance and design advantages in the production of
Conductus superconducting wire," said Jeff Quiram, STI's President and CEO.
"We continue to strengthen our global intellectual property portfolio to
protect our growing market position."
U.S. Patent No. 8,716,187 pertains to optimized compositions of Rare Earth
barium copper oxide (ReBCO) thin film superconductors using the Reactive
Co-Evaporation Cyclic Deposition and Reaction (RCE-CDR) process.
About STI's 2G HTS Wire RCE-CDR Manufacturing
Conductus® unique RCE-CDR deposition offers several key advantages to
successfully commercialize superconducting wire for large, emerging markets.
Importantly, deposition using RCE-CDR requires fewer manufacturing steps than
alternate deposition methods like MOD, MOCVD and PLD. Fewer steps reduces
total processing time and increases the likelihood of higher yield.
Conductus® highly controlled RCE-CDR deposition process grows crystalline
structures from very low cost raw materials in their bulk, solid state. Other
YBCO growth approaches are not as controlled and usually require the use of
costly chemical mixtures to deposit superconducting materials. The competing
processes require more buffer layers for proper crystal growth which increases
complexity and runtimes and reduces yield. Conductus® growth process is
simple, repeatable and commercially proven. In addition to the lower direct
cost of raw materials and the use of inexpensive substrate material,
Conductus® manufacturing process will be designed for high throughput and a
large superconducting growth area. Fewer process steps allows for less
production equipment per km of wire, which in turn translates into lower
cap-ex, less electricity use and a smaller production footprint.
