4) the electrical properties of the solid solution: the electrical properties of the solid solutions with varying concentrations of impurities (solute), or even generally appear continuous linear variation; however, often occur in the phase boundary mutation. For example PbTiO3 and PbZrO3 not excellent performance piezoelectric ceramic. PbTiO3 is ferroelectric phase transition is accompanied by a drastic change in the lattice parameters, and when cooled to room temperature, usually cracks occur, there is no pure PbTiO3 ceramics. PbZrO3 anti-ferroelectric. Both compounds having the same structure, Zr4 + and Ti4 + size almost continuously generates solid solution Pb (ZryTi1-y) O3, where y = 0 ~ 1. With different solid solution composed of different crystal structure at room temperature. Place in PbZrO3-PbTiO3 system is equivalent to the replacement, Jinan cyclohexanone, forming a complete solid solution structure, the electric field the basic balance, conductivity did not change significantly, under normal circumstances, the dielectric properties also changed little. But in the tripartite (rhombohedral) structure and the Quartet (tetragonal) crystal structure of the boundary (MPB) of the dielectric constant and piezoelectric properties of PZT solid solution obtained are better than pure PbTiO3 and PbZrO3 sintering performance is also good. Aliovalently replacement will produce ionic defect, causing major changes in the conductivity of the material, and that this change is proportional to the concentration of defects and impurities. ZrO2 lattice stability is a high temperature refractory material, melting point 2680 ℃, cyclohexanone price, but with a lot of volume shrinkage during phase transformation, high-temperature structural material which is fatal. If added CaO, cyclohexanone Jinan, the form and ZrO2 solid solution, no crystal transition, volume effect reduced to ZrO2 become a good high-temperature structural materials. After activation lattice form a solid solution, a certain distortion of the lattice structure, the state in a high activation energy, is conducive to the chemical reaction. Such as, Al2O3 high melting point (2050 ℃), is not conducive to the sintering, the inclusion of TiO2, sintering temperature can be decreased to 1600 ℃, this is because the Al2O3 and TiO2 form a solid solution, Ti4 + substitution Al3 +, the cyclohexanone manufacturers, positively, To balance the price, resulting in a positive ion vacancies, speed up the diffusion, in favor of sintering.
