MRI
Penn State MRL (since 1962)
1) Applications Driven – Basic Research
2) Exploratory Experimentation Approach:
-following Goethe; Faraday; Land.
3) Direct comparison with current best
practice to check viability in marketplace
This approach resulted in PSU-MRL being ranked #1 in the
World in 2003 by Thomson-ISI studies on the basis of highly
cited faculty.
MRI
What Justifies our Claim of
Revolutionizing 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.
MRI
Ditto: Revolutionizing Materials
Processing
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.
MRI
Revolutionary: Reacting Materials
with Physically Separate E and H
fields at 2.45 GHz
Comparing identical samples 4 cm. apart
one in (nearly pure) E field, one in (nearly pure) H field.
Showing RADICAL differences in resulting structures
and properties, totally non crystalline to very well
crystallized.
Tracking down by systematic “Exploratory
Experimentation” approach the only common factor
necessary for this phenomenon: the presence of
unpaired spins.
MRI
Not so Revolutionary is the:
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

Applications Driven Basic Research - A
• The World (With U.S. Lagging) Will
Absolutely - Certainly Move To Energy
Saving Technology
• Microwave/Laser Processes Offer That:
• Only Microwaves Offer it for Bulk Materials
Processing.
• Microwave Processing is Here For Sure.

Summary of Already Demonstrated Use of
MW in High-temperature Materials
Industry
• Sintering, Synthesis of All Ceramics
• Sintering of Powder-metals, Melting of Scrap Metals
• Now moving to:
• METAL EXTRACTION INDUSTRIES: Starting with steel,
then Ti, Cu etc.
• Entire Chemical Industry
