Ferroelectric perovskites |
摘要 |
<p>Pulverised ferroelectric perovskites with piezoelectric properties at temp.≤300 degrees C are fabricated by inserting fluoride ions into anion sites and/or oxygen gaps. Typical processes in a liq. method include a co-pptn. of the principle cations forming the perovskite, then mixing with a metallic or non-metallic fluoride, followed by thermal treatment at 600 degrees C allowing the insertion of the fluoride ions into the oxygen gaps or anion sites in the perovskite lattice.</p> |
