Crystal growth, structure and physical properties of crystals
Vesuvianite is an ortho-diorthosilicate of a general schematic formula X~19Y13Z18O68W10, where X – Ca and other cations, which occupy sites of coordination number 8, Y – cations occupying octahedrons and pentagonal polyhedrons: Al, Fe, Mg, Ti, etc., Z – Si in tetrahedrons, W – univalent and bivalent anions. Structures of vesuvianites are studied in dependence on a character of cation ordering i...
متن کاملGrowth, Mechanical, Thermal and Spectral Properties of Cr3+∶MgMoO4 Crystal
This paper reports the growth, mechanical, thermal and spectral properties of Cr(3+):MgMoO(4) crystals. The Cr(3+):MgMoO(4) crystals with dimensions up to 30 mm×18 mm×14 mm were obtained by TSSG method. The absorption cross-sections of (4)A(2)→(4)T(1) and (4)A(2)→(4)T(2) transitions are 12.94×10(-20) cm(2) at 493 nm and 7.89×10(-20) cm(2) at 705 nm for E//N(g), respectively. The Cr(3+):MgMoO(4)...
متن کاملDetermination of Crystal Growth Rate and Morphology of Barium Carbonate Crystals in a Semi-batch Crystallizer
A semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant pH value and constant temperature in the various relative supersaturations. Results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3, the k...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
