What Justifies our Claim of What Justifies our Claim of Revolutionizing Materials ScienceRevolutionizing Materials Science
1) Synthesis of most important ceramic phases (e.g. BaTi03, YIG, phosphors in 3-5% of the typical time.
2) Reaction of oxide ceramic powders normally requiring 10 hrs (= 36,000 seconds) in 5-15 seconds.
3) Discovery of an anisothermal process which reacts two phases at different temperatures, never before in human history.
4) Synthesis of high temperature pure nitride, carbide powders, and fibers in 30 seconds.

1) Sintering any ceramic material to theoretical density and/or transparency in 3-30 minutes.
2) Sintering commercial WC/CO tools continuously, reducing the cycle time by 90%.
3) Reacting and sintering metallic powders in microwaves.
4) Melting bulk metals in microwave fields.
5) Creating a new state of matter with a wide range of compositions in a few seconds by decrystallizing solids.

Showing RADICAL differences in resulting structures and properties, totally non crystalline to very wellcrystallized.
Tracking down by systematic “Exploratory Experimentation” approach the only common factor necessary for this phenomenon: the presence of unpaired spins.

Total neglect of these really new results (in the U.S.)
• By academic colleagues• By U.S. Industry• By U.S. agencies using peer review
Exactly the same treatment was accorded to the discovery of the (SOLUTION-) SOL-GEL-PROCESS
Review paper published in J.Am. Cer. Soc. In 1956.Became the first citation classic in entire Ceramics field.
Before say 1976, outside of Penn State circle, perhaps a dozen persons had used it.
Since 1980, it has probably been actually used in 30,000 (-50,000)papers

• Microwave/Laser Processes Offer That:
• Only Microwaves Offer it for Bulk Materials Processing.
• Microwave Processing is Here For Sure.
