Effect of impurities on crystal growth rate of ammonium pentaborate

Determination of nonlinear absorption (β) and refraction (n2)by the Z-scan method: third-order nonlinear optical properties of π- conjugated Potassium Pentaborate crystal

“…At room temperature KB 5 crystal belongs to orthorhombic system and the cell parameters are a = 11.068 Å, b = 11.175 Å and c = 9.058 Å, α = β = γ=90° and with unit cell volume V = 1116.38 (Å) 3 and these values match well with the corresponding values reported [4][5][6][7][8] given in parentheses.…”

“…These boratecrystals generally possess chemical stability, high damage threshold and high optical quality, as wellas wide range of transparency far into the ultraviolet on account of the rather large difference in the electronegativities of B and O atoms. The properties determining an effective NLO material particularly, the borate compound materials have been discussed by several researchers [1][2][3][4][5][6]. KB 5 crystal is un-colored, optically biaxial positive with optic plane 010 [7].…”

Abnormal Grain Growth in Barium Titanate Doped with Alumina

“…Addition of a dopant can therefore cause the growth rate to increase, pass through a maximum, and then decrease with further addition of dopant. This behavior has been observed in crystals grown from solution in several organic and inorganic systems 58,59,61–63 …”

Theoretical Evaluation of Mass Transfer Coefficients in Solution Crystallization

“…Despite its importance, very little is known about solid-liquid mass transfer coefficients in crystallization. Several experimental works for the determination of mass transfer coefficients in crystallization have been reported (Martins and Rocha, 2006;Van der Gun et al, 2005;Sahin et al, 2004;Louhi-Kultanen et al, 2001). On the other hand, mass transfer coefficients in gas-liquid stirred systems have received substantial attention in the past, and many correlations can be found in the literature (Nienov, 1992).…”
