some oxide superconductors adopt a crystal structure similar to that of perovskite CaTiO3. the unit cell is cubic with a Ti4+ ion in each corner, a Ca2+ ion in the body center and O2- ions ate the midpoint of each edge.
(a) if the unit cell edge length is 3.84 A, what is the density of perovskite in g/cm3??
Homework Answers
a = 4r/3 for
BCC
a = 4*3.84*10-8/1.732 = 8.87*10-8 cm
d = ZM/N0a3
= 2*136/6.023*1023 *(8.87*10-7)3
= 272/53.424*102
= 0.0509g/cm3 >>>>> answer
