Molybdenum disilicide composites for glass processing sensors

摘要

In October 1998, we initiated a Project funded by DOE/OIT/AIM/Glass Industry on'Molybdenum Disilicide Composites for Glass Processing Sensors'. The objective of this Project is to develop strong, tough, thermal shock resistant, and molten glass corrosion resistant molybdenum disilicide (MoSi2) composite tubes by plasma spray-forming techniques, that can be employed as protective high temperature sensor sheaths for a variety of advanced sensors and controls throughout the glass industry. The emphasis is on the development of advanced MoSi2-Al2O3 coated. Laminated, and functionally graded composite tubes. With Accutru International corporation, we are developing silicide-based protective sheaths for self-verifying temperature sensors which may be used to accurately measure temperature in glass furnaces in glass furnaces and other industrial applications. With Combustion Technology Inc., we are developing silicide-based periscope sight tubes for the direct observation of the surfaces of glass melts in glass furnaces. With Exotherm Corporation, we are characterizing combustion-synthesized silicide composite tubes.
