Momentive Performance Materials Titanium Diboride/Boron Nitride Composite Vacuum Metallizing Boat (discontinued **)
Categories:	Ceramic; Boride; Ceramic Matrix Composite; Nitride
Material Notes:	Intermetallic composites from Advanced Ceramics are used vacuum metallizing industry. These ceramics withstand higher operating temperatures, have lower moisture sensitivity, low thermal expansion, and high density. Available in a selection of resistance ranges, IMC boats can be tailored to match available power supplies. These unique properties provide the vacuum metallizer a resistance heated source that operates at high evaporation levels, and is extremely durable in operation. Information provided by Momentive Performance Materials, formerly GE Advanced Ceramics.
