1. A high-temperature device, comprising:
a container comprising an internal cavity, wherein the internal cavity comprises a reactive material and a gaseous headspace, and wherein the reactive material is maintained at a temperature of at least 200° C.;
a seal that seals the internal cavity of the container from an environment external to the container, wherein the seal comprises a ceramic component, and wherein the seal is exposed to both the reactive material and the environment external to the container;
a conductor that extends from the environment external to the container through the seal to the internal cavity of the container;
a shield coupled to the conductor or to a wall of the internal cavity and positioned within the gaseous headspace between the reactive material and the seal; and
a metal sleeve coupled to the conductor and to the ceramic component, wherein the metal sleeve is coupled to the ceramic component by a braze joint comprising a braze, and wherein the braze is formed of a material that is substantially unreactive to air and prevents diffusion of air into the container when the reactive material is maintained at the temperature of at least about 200° C. for a time period of at least about 1 day.
