-tree crystal into the equiaxed crystal, and less primary phase and more eutectic structure are observed. Moreover, in eutectic alloy, the spacing of eutectic phase decreases markedly... by the crystal latent heat release of the more eutectic structure. Therefore, below the L-LST temperature, there are Sn-rich and Bi-rich clusters in the melt, which are SRO structure. This liquid structure......
slaking and cracking when the ambient humidity is more than 40%, which brings more difficult on CLBO surface finishing. According to the performance and structure characteristic of CLBO crystal, a new...

strong diffractions occurred in a narrow angle range, so it was difficult to orientate the single crystals of BaY2F8. In this paper, based on the structure characteristics and XRD data, the crystal habit of BaY2F8 was analyzed. The strong bond in crystal structure of BaY2F8 was Y-F2-Y, which stretched to the shape of chain along the direction of [001]. And this was an advantaged direction......
the intricate wax crystal morphology and structure. Based on the characterization, the effects of microstructures and oil composition on the waxy crude viscosities are analyzed quantitatively. It further...J. Cent. South Univ. Technol.
