AbstractLarge single crystals of optical quality of bis(guanidinium)zirconium bis(nitrilotriacetate)hydrate have been grown from aqueous solutions. Complete elastic, thermoelastic and piezoelastic tensors have been determined by ultrasonic methods. In addition, the tensor of thermal expansion, refractive indices, dielectric and piezoelectric constants have been studied in the range between 210 K and 330 K. Most physical properties investigated show a strong anisotropy. The piezoelectric constant

SummaryYellow sapphirine with a doubled b-axis occurs in enstatite-hornblende-sapphirine rocks at the contact between dolomite marble and yoderite-quartz-talc schist on Mautia Hill, Tanganyika. It has refractive indices α 1·725± 0·002, γ 1·732±0·002, 2Vγ66°, pleochroism a pale yellow, β pale lime green, γ pale pinkish orange, and a composition corresponding to Mg3·67Mn0·04Fe2+0·17Ti0·01Fe3+0·33Als·07Si1·75O20·00. Its unit-cell dimensions are approximately a 9·85 Å, b 28·6Å, c 9·96 Å, β 110° 30′, and its diffraction pattern exhibits diffuse streaks parallel to b*, on which lie diffuse intensity maxima representing the relics of certain types of sharp reflexions of normal sapphirine ; this is interpreted as indicative of partial MgAl ordering. The associated enstatite and hornblende have compositions Mg7·58Mn0·02Fe2+0·02Ti0·01Fe3+0·13Al[6]0·25Al0·41[4]Si7·59O24·00 and K0·04Na0·16Ca1·95Mg4·37Mn0·01Fe0·052+Ti0·04Fe0·253+Al0·42[6]Al0·91[4]Si7·09O22·24(OH)1·76respectively and are accompanied by accessory hematite and pseudobrookite. Preliminary heating experiments have demonstrated the transformation of single crystals of partially ordered Mautia sapphirine to single crystals of a defect spinel phase after 48 hours at 1287° C in air; normal disordered Panrimali sapphirine remains unchanged by similar heat treatment.

The Difference

Single crystals of cadmium selenide have been grown from the melt in vacuo . The coefficient of absorption, both for the ordinary and extraordinary beam, has been measured over the wavelength range 0.73 to 2.0 μ . Dichroism has been observed in the vicinity of the absorption edge. A method for the measurement of the difference between the refractive indices in cadmium selenide for the ordinary and extraordinary beam has been worked out. These measurements were carried out at room, and at liquid nitrogen temperatures. Birefringence was found to change from positive to negative near the absorption edge. Direct measurements of the refractive indices were carried out for the wavelength region 0.73 to 2.0 μ .
