Evidence Details
Equipment-detail evidence: source values include 1:0.2, 200 °C, 30 min. Entities: XH-8000Plus, X-100.
Release-kinetics evidence: source values include 900 °C, 3 h.
Equipment-detail evidence: source values include 1:0.2. Entities: X-100.
The maximum electronic conductivity of SFN113 and SFN327 reaches 90 S cm-1 at 610 ◦C and 28 S cm-1 at 590 ◦C, respectively. Surprisingly, the conductivity of SFN113 bar coated with SFN327 arrives at 123 S cm-1, which is higher than that of two single-phase materials.
The obtained k value of the SFN113 bar with 4.569 mg cm-2 SFN327 coating is much higher than that of the bare SFN113 bar. As the temperature decreases, the ratio of the k of the SFN113 bar with 4.569 mg cm-2 SFN327 coating to the bare SFN113 bar continues to increase, reaching a maximum of 7.
Additional source evidence: source values include 123 S, 7 fold. Entities: cm-1.
Additional source evidence: source values include 700 °C. Entities: cm-2.
