Sol-gel method was regarded as a kind of soft chemistry technique, by which fine powders would be obtained easily, meantime the amount of raw materials could be controlled accurately [2].
Experiment In this study, Sc2O3 (99.99%), Bi (NO3)3·5H2O (AR), Pb (COOCH3)2·3H2O (AR) and Ti(OC4H9)4 (AR) were chosen as starting materials to provide Sc3+, Bi3+, Pb2+ and Ti4+.
Besides, C6H8O7·H2O (AR), HNO3 (AR), NH3·H2O (AR), H2O2 (AR) were used as auxiliary materials.
Starting materials were mixed according to stoichiometric proportion of 0.365BiScO3-0.635PbTiO3 and sol solution was obtained.

In addition, the new findings may be helpful in understanding the dynamic behavior of these materials especially in engineering projects in which these granular materials are used.
This curve shows that 100% of the soil materials are of a diameter less than 25mm.
Based on the tested materials, the following conclusions are made: 1.

Shape memory polymers are a class of smart polymeric materials which are able to “memorize” a permanent shape and that can be manipulated in a way that a certain temporary shape will be “fixed” under appropriate conditions.
Experimental and Methods Materials. 4,4’-methylenediphenyl diisocyanate (MDI, Aladdin, 99wt% purity), 1,6-Hexanediol (HDO, Aladdin, 99wt% purity) and 2,2-Dimethylol Propionic Acid (DMPA, 99wt% purity) were commercially available.
The thermal stability of the liquid crystalline polyurethane is affected by the raw materials used, and the proportions of the hard and soft segments, the density and type of crosslinking bonds, and the chain extender and synthesis method [11].
