Oxidation-resistant ferritic steel alloys for high temperature applications consist essentially of chromium (Cr) in an amount from about 18 to about 25 atom percent, tungsten (W) in an amount from about 0.5 to about 2 atom percent, manganese (Mn) in an amount less than about 0.8 atom percent, aluminum (Al) in an amount less than about 0.2 atom percent, silicon (Si) in an amount less than about 0.1 atom percent, and rare earth metals that includes neodymium (Nd) in an amount from about 0.002 to about 0.2 atom percent with the balance being iron (Fe). Also disclosed herein are solid oxide fuel cells that include separators formed for the oxidation resistant ferritic alloys.

Ferritic steels for solid oxide fuel cells and other high temperature applications

A system having a heat source, a component coupled to the heat source, and at least one thermistor coupled to the component and adapted to monitor temperature of the component, wherein the thermistor has a core-shell microstructure having a shell disposed about a core, the core comprising CrOand the shell comprising a rare earth element compound.

Temperature measuring device and system and method incorporating the same

High-permeability, low-core-loss soft magnetic composite materials, compositions containing the same, and methods for making the same are described. These magnetic materials are made by forming fiber or flake shaped particles from a ferromagnetic material, annealing the particles, and then coating an insulating material on the particles. These particles can then be compacted to form an article that has high permeability, high saturation, low core loss, and is a suitable replacement for laminations in various applications, such as motors.

Coated ferromagnetic particles and compositions containing the same

A coated ferromagnetic particle comprises a ferromagnetic core and a coating. The coating comprises a residue resulting from a thermal treatment of a coating material comprising a polymer selected from the group consisting of polyorganosiloxanes, polyorganosilanes, and mixtures thereof. A composite magnetic article comprises a compacted and annealed article of a desired shape. The composite magnetic article comprises a plurality of coated ferromagnetic articles. Each coated ferromagnetic particle comprises a ferromagnetic core and a coating. The coating comprises a residue resulting from a thermal treatment of a coating material comprising a polymer selected from the group consisting of polyorganosiloxanes, polyorganosilanes, and mixtures thereof.
