H.C. Starck‘s furnace group delivered a uniquely engineered, high-temperature refractory-metal hot zone to a furnace manufacturer. Collaborating with the customer, H.C. Starck fabricated a 2912°F (1600°C) hot zone designed to operate in a vacuum, with certain inert gases or in a reducing atmosphere. By simulating the temperature of each layer, H.C. Starck’s engineering team ensured the proper materials were applied throughout the hot zone. Benefits of H.C. Starck’s refractory materials include increased heating efficiency, product contamination elimination, reduced time to evacuate and prolonged furnace service life.
