Abstract:

Natural kaolinite has been used as a starting material for preparing the fast ion conductors of Na1+2x+yAlxSmyZr2-x-ySixP3-xO12 system(Al-Sm-Nasicon)by high temperature solid phase reaction. A Nasicon phase with C2/c or R (3) over bar c space group exists in a rather wide composition region of above system. The unit-cell dimensions of Al-Sm-Nasicon change with changing x and y. The maximum conductivity in the above system is 1.25 X 10(-2) S, cm at 400 degrees C for the initial composition x= 0.5, y = 0.3, its activation energy is 37.31 KJ/mole in the temperature range 200 similar to 400 degrees C.
