Ceramic shrinks when the heat goes on
Article Abstract:
Researchers from Oregon State University and Brookhaven National Laboratory in NY have found a ceramic known as zirconium tungstate that when heated, shrinks rather than expands. The ceramic, composed of oxygen, zirconium and tungsten, could be applied in electronic circuit board construction.
