The stress induced phase transformation of 3Y-TZP from the tetragonal to monoclinic structure results in a volume expansion which deters crack propagation and contributes to the overall strength and toughness of the ceramic.
Several studies have reported that the mechanical properties of 3Y-TZP depend on various factors such as the grain size and chemistry [6, 7].

Ion exchange method, can be used to separate almost all of the inorganic salt ions, also used to separate many organic compounds with complex structure and similar properties.

In the presence of SDS the entropy of polymeric chains decreases and the polymeric chains become stretched, which explains the colour change, leading to absorption at longer wavelengths; when the amount of polyaniline, in the blend, increases the variation of entropy is not so high in the presence of SDS, due to the effect of lamellar structure of PANi, and the transport process is less SDS dependent as the reversibility of SDS-blend increases. 0 20 40 60 80 100 0.4 0.8 1.2 1.6 2.0 C / (mmol SDS / g of polymer) [SDS] / mM Figure 2.
