Instrumentation for Microwave Processing
Abstract
As proposed, and then amended in our request for a no-cost extension of August 1997, we purchased the following systems: (a) Automatic polishing system (including multiple specimen holders for mounted and unmounted specimens and a magnetic wheel and magnetic polishing plates for polishing cloths to facilitate the polishing process and minimize use of consumables; (b) Optical extensometer system to be used as a non-contact optical dilatomer. Includes table to facilitate focusing on sample and computer and software to allow the extensometer to be used for closed loop process control; (c) Centrifuge to allow processing of nanopowders (both consolidation of commercial nanopowders and preparation of experimental nanopowders); (d) Zeta potential analyzer to allow evaluation of size and surface charge of nanopowders. This is being used for development and dispersion of nanopowder systems; (e) Optical pyrometry system, three pyrometers on a computer controlled translation table were purchased to allow process control over at least room temperature to 2000 deg C. We believe that the system is capable of reliable temperature measurement and process control at higher temperatures, but we have not yet attempted to process at temperatures above 2000 deg C.
