PROCESSING CERAMIC FILAMENTS IN A SINGLE-MODE CAVITY WITH A VARIABLE FREQUENCY SOURCE

摘要

Rapid feedback control with a variable frequency microwave source provides practical process control over the heating of continuous ceramic filament tows and tubes in a single mode cavity. Process temperatures are regulated despite large variations in dielectric loss and heating as a filament tow or tube moves through the microwave cavity. Applied process control for microwave heating of NICALON tows and mullite tubes will be described.
