Hot zones are used for various high-temperature industrial processes, including vacuum heat treating and sinteresting, hot isostatic pressing, and crystal growth. These are useful processing techniques for metals with high-melting points, such as titanium alloys, silicon nitride alloy composites, and zinc selenide for creating components, metal sheets, and castings. Hot zone grown sapphire is widely used for optical applications, owing to its excellent hardness and good transparency when polished.
Hot zones and the manufacturing techniques they enable are used in a variety of industries, including aviation and defense, the electronics and semiconductor industries, and optics. All of these are very demanding applications that require excellent metal purities, and refractory metal hot zones help avoid contamination in the furnace and ensure better quality vacuum conditions.
Materials & Specifications
Hot zones often have to be customized for a particular application to achieve the desired manufacturing result. The exact hot zone designs are very demanding and this is why the Elmet Technologies (formerly H.C. Starck Solutions) molybdenum and tungsten materials and fabricated products are ideal for use as furnace components and fixtures.
