Densification of glass powder studied by master sintering curve and master kinetic curve methods

چکیده
The master sintering curve method was applied to analyze the and crystallization behavior of 15Na2O.10CaO.75SiO2 (SLS) 17Na2O.33CaO.50SiO2 (NC2S3) glasses, in mol %. densification samples successfully analyzed using (MSC) method; it gives activation energy Q = 310–340 kJ.mol−1, which is good agreement with expected viscous flow. While obtained enables predicting SLS glass, actual results are different from estimated data for NC2S3. NC2S3, determined by constructing Master Kinetic Curves (MKC) lower than energy: this impairs prediction ability MSC NC2S3 glass.

Master sintering curve for Gd-doped CeO2 solid electrolytes
The sintering behavior of gadolinia-doped ceria powders was studied by the master sintering curve (MSC). Dilatometric analyses of powders produced by a soft chemical method were performed to provide the experimental data set for the construction of the MSC. The assumed model provided good fittings of the MSC and the activation energy for the sintering of Ce1-xGdxO3-d, with x = 0, 0.05, 0.1, and...

The non-isothermal transformation rate curves of metallic glasses are analyzed with the Master Curve method grounded in the Kolmogorov-Johnson-Mehl-Avrami theory. The method is applied to the study of two different metallic glasses determining the activation energy of the transformation and the experimental kinetic function that is analyzed using Avrami kinetics. The analysis of the crystalliza...

Sintering and Foaming of Barium Silicate Glass Powder Compacts
The manufacture of sintered glasses and glass-ceramics, glass matrix composites, and glass-bounded ceramics or pastes is often affected by gas bubble formation. Against this background, we studied sintering and foaming of barium silicate glass powders used as SOFC sealants using different powder milling procedures. Sintering was measured by means of heating microscopy backed up by XPD, differen...
