b336a53425 1323 (1942); Vol. 64, p. Such defective polycrystalline structures would appear to be the basic elements of nanoscale materials science, and, therefore, provide the first step in developing a more rigorous understanding of the mechanisms involved in microstructural evolution in inorganic systems such as sintered ceramic nanomaterials.[31][32]. Journal of Materials Science. But if they are small enough to be colloids, then their irregular motion in suspension can be attributed to the collective bombardment of a myriad of thermally agitated molecules in the liquid suspending medium, as described originally by Albert Einstein in his dissertation. in Microstructural Control Through Colloidal Consolidation, Aksay, I.A., Adv. ^ ^ Rosa-Fox, N. 42, p. Particles and polymers[edit].
Even small quantities of dopants, such as organic dyes and rare earth elements, can be introduced in the sol and end up uniformly dispersed in the final product. Science. In addition, any fluctuations in packing density in the compact as it is prepared for the kiln are often amplified during the sintering process, yielding inhomogeneous densification. (2014). Colloidal Dispersions, Russel, W.B., et al., Eds., Cambridge University Press (1989) Glasses and the Vitreous State, Zarzycki. The ability of a condensed body to respond to a mechanical force by viscous flow is thus strongly dependent on the time scale over which the load is applied, and thus the frequency and amplitude of the stress wave in oscillatory experiments.[47][48]. Journal of the American Ceramic Society. It is further shown that the phase transition can be induced by the application of an electrical field across the gel. 124 (1981) ^ Tanaka, T., Hocker, L.O. ^ Hench, L.L.; J.K.
