چکیده انگلیسی
Sodium potassium tartrate tetrahydrate-NaKC4H4O6·4H2O known as Rochelle salt is a well-known ferroelectric. This paper deals with the following topics: (i) the Sankaranarayanan-Ramasamy method of growth of a parallelepiped-shaped single crystal of Rochelle salt having the (1 0 0), (0 1 0) and (0 0 1) planes mutually perpendicular to each other, (ii) evaluation of the second-order elastic stiffness constants C11, C22, C33, C44, C55 and C66 using the parallelepiped-shaped single-crystal sample of Rochelle salt, (iii) growth of large [0 1 1]-, [1 0 1]- and [1 1 0]-oriented cylindrical-shaped single crystals of Rochelle salt from appropriately prepared seeds using the same method, (iv) determination of elastic constants C23, C13 and C12 using the [0 1 1]-, [1 0 1]- and [1 1 0]-oriented single-crystal samples of Rochelle salt, respectively, and (v) calculations of elastic compliance constants S11, S22, S33, S44, S55, S66, S12, S23and S13, Young's modulus E, bulk modulus K, Poisson's ratio Ï
, linear compressibility β1, β2 and β3 along the three principal directions and volume compressibility β of the crystal.
