• Synthesis and characterization of inorganic non-linear optical material: Potassium sodium
hydroxide borate hydrate (KSB) single crystal

Materials Letters 296, 129868 (2021)
C. Ramki and R. Ezhil Vizhi

The article discusses the synthesis and characterization of

inorganic non-linear optical material potassium sodium
hydroxide borate hydrate (KSB) single crystal. Here we
used the slow evaporation method for preparation. In this

letter, crystal growth, unit cell measurement, FTIR, and
thermal analysis are described to prove that the grown
single crystal (KSB) is a trustworthy material.

• Structural, dielectric, and non-linear properties of potassium hydrogen oxalate-trihydroxy
boron (KHC2O4B(OH)3) single-crystal

This report synthesizes transparent potassium hydrogen

oxalate-trihydroxy boron (KHOB) crystal by the solution
growth method at ambient temperature. The structure and
third-order non-linear characteristics of the developed

crystal were studied first. Moreover, the information
about the metastable zone width and various parameters
involved in the dielectric behavior of KHOB were

investigated systematically.

• Effects of synthesis and sintering temperature in BCT-BST ceramics

It is observed that the solid-state reaction method requires a higher
calcination temperature. Also, the ceramics prepared by the solid-state

reaction method have a comparatively larger crystallite size (50 nm) and
average particle size (1 µm). In the case of dielectric studies, a huge dielectric
constant of 18,000 is found for ceramics prepared by the sol-gel route. The

material has ferroelectric to paraelectric transition, and the ferroelectric
studies confirm the ceramic's soft nature.
