چکیده
Abstract This is the first study to conduct flash sintering of 3 mol% yttria-stabilized zirconia (3YSZ) ceramics at room temperature (25 °C) under a strong electric field, larger than 1 kV/cm. At standard atmospheric pressure (101 kPa), probability successful approximately half that low pressure, lower 80 kPa. The success proposed process was determined based on high arc performance different pressures ranging from 20 100 3YSZ samples achieved maximum relative density 99.5% with grain size ∼200 nm. results showed as decreases, onset field corresponding empirical formula flashover voltage. Moreover, found be triggered by surface ceramic samples, and sample surfaces floated upward before complete overly pressures, resulting in failure sintering. reveals new method for facile preparation flash-sintered temperature, which will promote application industry.

The results of a study of ultra-rapid (flash) sintering of oxide ceramic materials under microwave heating with high absorbed power per unit volume of material (10-500 W/cm³) are presented. Ceramic samples of various compositions-Al₂O₃; Y₂O₃; MgAl₂O₄; and Yb(LaO)₂O₃-were sintered using a 24 GHz gyrotron system to a density above 0.98-0.99 of the theoretical value in 0.5-5 min without isothermal...

This report presents the results obtained by the five U.S. participating laboratories in the Versailles Advanced Materials and Standards (VAMAS) round-robin for fracture toughness of advanced ceramics. Three test methods were used: indentation fracture, indentation strength, and single-edge pre-cracked beam. Two materials were tested: a gas-pressure sintered silicon nitride and a zirconia tough...
متن کاملLow-temperature sintering of MnO2-doped PZT–PZN Piezoelectric ceramics
The effect of MnO2 addition on the microstructural evolution and piezoelectric properties of low temperature sinterable PZT–PZN ceramics was investigated. When a small amount of MnO2 (≤0.5 wt% ) was added, the Mn ions were homogeneously dissolved in the PZT– PZN ceramics, leading to full densification at a temperature as low as 930 °C. However, the further addition of MnO2 hindered the densific...
