Growth of Beryllia Single Crystals

Abstract: Single crystals of beryllia have been grown by two methods. One method exploits the hightemperature reversible reaction B e 0 + HzO % Be(OH)2. The other is a flux method, in which B e 0 is dissolved and precipitated as single crystals in a lithium molybdate flux. Characteristics and remaining problems of the two methods are discussed, and the crystals produced are described.

“…Consistent with this, a Wulff construction [37,38] based on the surface energies in Table 1 suggests that BeO crystals exposing (100), (001) and (001) faces exhibit a prism shape with large (100) faces and small (001) and (001) faces. Some synthetic crystals which expose these faces have the same prism shape [39]. When BeO is grown on Be(001), the BeO(001) face is hidden by the Be(001).…”

“…The ILSF in this structure lead to the formation of inversion twins, so called because the crystal regions on each side of the twin boundary, or the stacking fault boundary, have opposite or inverted crystal polarities. The inversion twins are most evident in the morphology of crystals grown from solution in lithium molybdate (Austerman, 1963). Photographs of BeO bicrystals containing ILSF are shown in Figs.…”

“…Однако лишь спустя семьдесят лет были выполнены первые спектроскопические исследования широкополос-ной ультрафиолетовой (УФ) люминесценции BeO при комнатной температуре [7,8] и температуре жидкого воздуха [9]. Появление объемных монокристаллов BeO оптического качества [10,11] стимулировало детальные исследования кристаллографической структуры, люми-несценции и электронных возбуждений в BeO.…”
