Whisker reinforced glass ceramic. Quarterly progress report No. 1, September 27, 1994--December 27, 1994

摘要

The goal of this project is to investigate the physical properties of an in-situ whisker reinforced glass ceramic material and to produce prototype heat exchanger tubes for testing in a coal combustion environment. The in-situ whisker reinforced glass ceramic process was developed and patented at Virginia Tech and licensed to Materials Technologies of Virginia. Completion of this project will demonstrate the potential for this new material to replace existing heat exchanger materials due to its superior chemical and physical properties. The technical progress has been in three areas: Construction of a slurry filtration apparatus for preparation of glass ceramic samples, construction of a prototype heat exchanger preparation apparatus, and test melts of the glass powder with parameters for composition, heat treatments, quenching, and milling.
