The perovskite BiInO 3 can be prepared using high-pressure synthesis. At room temperature, it has Pna2 1

Question:

The perovskite BiInO₃ can be prepared using high-pressure synthesis. At room temperature, it has Pna2₁ space-group symmetry, with an SHG signal 120–140 times that of αquartz. Upon heating, no phase transitions occur until it decomposes into In₂O₃ and Bi₂₅ InO₃₉ at 873 K. Based on this information, what can you say about the potential of BiInO₃ for application as

(a) A pyroelectric,

(b) A ferroelectric,

(c) A piezoelectric?

(d) How would you expect the dielectric constant to change upon heating?
