Growth of a bulk-size single crystal of sulphamic acid by an in-house developed seed rotation solution growth technique and its characterization

Abstract

A bulk sulphamic acid single crystal has been grown by a modified seed rotation technique. The lattice dimensions of the grown single crystal were confirmed using powder X-ray diffraction, and it was found that it crystallized in an orthorhombic structure with space groupPbca. The strain in the lattice was calculated by the Williamson–Hall equation. The crystalline perfection was examined by high-resolution X-ray diffraction and found to be extremely good (the single peak of the rocking curve having an FWHM of ∼8.0′′). The luminescence behaviour was recorded in the wavelength region between 400 and 630 nm using an Xe flash lamp which acts as an excitation source. The shock damage threshold was measured for the grown crystal in order to determine the mechanical capability of the title compound. The thermal parameter of sulphamic acid was calculated by photoacoustic spectroscopy.

Rapid enhancement of optical transparency on glycine phosphite crystals by shock waves

“…Surface defects have a greater influence over the optical transmission of crystals. The optical microscopic images of sulphamic acid crystals were reported under shocked conditions, where the numbers of pits were reported to have increased with the number of shock pulses 47 . In the case of L-Arginine hydrobromide monohydrate crystal, pits are formed under shocked conditions and they increase with the number of shock pulses whereas they crack after the 47’th shock 48 .…”

Evaluation of structural, optical and mechanical behaviour of L-argininium bis(trifluoroacetate) single crystal: An efficient organic material for second harmonic generation applications

“…The single peak reveals that the titled compound does not contain any structural grain boundaries that show crystalline perfection is quiet good. Since, grain boundaries tend to induce deformities, absence of these in the grown crystal shows its suitability for practical application [33,34].…”
