Vacuum Materials

The application fields of vacuum materials are very broad, covering the range from silver and gold thread materials to food processing, medicine, and electronic related equipment such as semiconductors, optical magnetic disks, and liquid crystal displays. The materials are very closely tied to current high technology.

Fire and heat resistant materials are available, starting with crucibles for melting of various metals with different melting points. The abundant lineup includes products made of alumina, magnesia, zirconia, and other materials.

• Materials: Alumina, mullite, magnesia, zirconia, spinel, graphite, silicon nitride, and silicon carbide

Carbon Fiber Products

Insulation materials, consisting of carbon and graphite fibers for vacuum furnaces, are provided with excellent heat resistance and dimensional stability. The materials are optimum for furnaces with inert gas environments, such as vacuum furnaces. The low heat capacity and lightweight of the materials promises good energy efficiency.

• Material: Graphite fiber
(baked at +2000 °C)
• Products (shapes): Felt, formed thermal insulation materials, paper, bulk, and yarn

Graphite Products for Vacuum
Furnaces

Graphite products, such as heater materials, vacuum furnace electrodes, structural materials, crucibles, and jigs, with excellent heat tolerances up to +3000 °C in a vacuum. The materials, used in such areas as single crystal drawing equipment and thermal processing furnaces, are indispensable in leading-edge technologies.

Processing Products for High Melting Point Metals

Machined products of high melting point metals (+2500 °C or more) with excellent chemical stability and machining precision can be entrusted to us with confidence. Various products, including crucible liners for EB deposition and parts for ion injection equipment, are available.

• Materials: Molybdenum, tungsten, tantalum, etc.
