Planar Targets Made from Molybdenum-Niobium Alloy Description
Stanford Advanced Materials (SAM) offers high-quality planar targets made from a Molybdenum-Niobium alloy (MoNb) designed for advanced thin film deposition applications. This alloy typically consists of 90% Molybdenum and 10% Niobium, combining the high melting point, thermal stability, and electrical conductivity of Molybdenum with the enhanced mechanical strength and corrosion resistance of Niobium.
SAM provides planar MoNb targets in various purity grades (99.9% to 99.999%) that ensure minimal impurities for high-performance coating applications. These targets are available in various shapes, including Plates, Discs, and custom dimensions, making them compatible with various sputtering systems. The addition of Niobium improves resistance to oxidation and alkalinity corrosion, making MoNb alloys ideal for demanding environments where durability and consistent performance are critical.
SAM’s planar MoNb sputter targets are manufactured with precise grain structure control and uniform composition, ensuring excellent adhesion and film quality during deposition. With strict quality controls and customizable specifications, SAM provides reliable solutions for sectors requiring high-performance thin films, thereby supporting innovations in electronics, optics, semiconductor manufacturing, and other advanced manufacturing areas.
