Studies from Brno University of Technology Yield New Information about Ceramics

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Researchers detail new data in Ceramics. According to news reporting originating in Brno, Czech Republic, by VerticalNews journalists, research stated, "The progresses of the relative density, average grain size (GS), and maximum pore size entering into the final sintering stage are investigated in 3mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP) compacts in the range of 87%similar to 99% theoretical density."

The news reporters obtained a quote from the research from the Brno University of Technology, "It is found that during conventional pressureless sintering, the pores in the compact enlarged dramatically, which appears to be the major obstacle for preparing fully dense nanoceramics. Transparent 3Y-TZP nanoceramics with an average GS of 87nm were prepared by exploiting microstructural refinement on nanoscale."

According to the news reporters, the research concluded: "The yields a maximal optical transmittance of 67% and shows no noticeable low-temperature degradation after 100h aging at 134 degrees C under a hydrothermal pressure of two bars."
