Nonisothermal Techniques for Studying Initial-Stage Sintering

Nonisothermal techniques for analyzing initial‐stage sintering are reviewed. It is shown that in principle they permit the determination of all the sintering parameters (rate law, activation energy, and diffusion coefficients) normally obtained from isothermal experiments. Comparison with results fr...

Zusammenfassung:	Nonisothermal techniques for analyzing initial‐stage sintering are reviewed. It is shown that in principle they permit the determination of all the sintering parameters (rate law, activation energy, and diffusion coefficients) normally obtained from isothermal experiments. Comparison with results from isothermal experiments performed on the same materials (UO2 and ThO2 gel) demonstrates the validity and accuracy of the nonisothermal techniques.
