Sodium Potassium Tartrate is also a vital ingredient of Fehling's Solution and a ferroelectric crystal
often used as a component of Fenton's reagent.
The Curie temperature of a ferroelectric crystal
has great importance as it is useful in studying various properties of the crystal.
This system is based on a ferroelectric crystal
with similar photorefractive properties to IBM's polymer-based system.
Compared with ferroelectric crystals
(e.g., (Ba,Sr)Ti[O.sub.3]), the nematic LC has a lower bias voltage, which makes it more suitable for portable reconfigurable electromagnetic wave device design [11-14].

There are many literatures about the periodically poled ferroelectric crystals
reported, such as periodically poled LiTa[O.sub.3] (PPLT), periodically poled KTiOP[O.sub.4] (PPKTP), and periodically poled RbTiOAs[O.sub.4] (PPRTA) [23-25].
It has become achievable due to development of the domain engineering methods in nonlinear optical ferroelectric crystals

are characterized by their asymmetric or polar structures.
Quartz and ferroelectric crystals
, such as tourmaline and Rochelle salt, are good examples of piezoelectric materials, but ceramic lead zirconate titanate, PZT, is the most widely-used material for energy harvesting.
