摘要:
AbstractInfinite symmetry is referred to for describing in a more rational manner the morphology of certain crystals and crystal, particularly mineral aggregates. Their non‐crystallographic forms depend on the peculiarities of their structure, enhanced growth along preferred directions and on the symmetry and composition of the growth environment. Apart from the seven Curie forms others, fitting the corresponding point groups are suitably added as variants of the growth geometry, applicable also to the property of matte

摘要:
AbstractBased on the model of a so‐called Near Surface Transition Layer (NSTL) proposed by HERMANand ANDERSSONwe discuss the possible role of clusters during MBE growth. Moreover, intentional use of small clusters instead of single atoms as beam constituents may contribute to improvements in crystal quality even at low substrate temperature and high growth rat

摘要:
AbstractExperimental evidence has been obtained that both α‐ and β‐phase BaB2O4material can be grown directly from pure melts. Growth of α‐phase material onto a platinum rod is initiated by α‐phase structural centers present in the melts which are stable at temperatures around or just above the melting point. Overheated melts in which solid nuclei are destroyed have modified freezing characteristics and form β‐phase material. β‐phase material can be produced onto a platinum rod at temperatures well above the reported phase trans

摘要:
AbstractMagnesium hydroxoaluminate hydrates were coprecipitated from different mixed metal cation solutions at Mg/Al2ratios from 1 to 4 by ammonium hydroxide. The coprecipitations were monitored by potentiometric titration and the final precipitate compositions were examined by chemical analysis, X‐ray diffraction, infra‐red spectrophotometry and thermal analysis. The process of coprecipitation was similar to that for coprecipitation with sodium hydroxide but large excess of ammonium hydroxide was required for complete reaction atpHs from about 8 to 10.At Mg/Al2= 1, the main phase was probably Mg(H2O)h[Al(OH)4]2;at Mg/Al2= 2, the main phase was probably Mg2(H2O)h[Al2(OH)10];at Mg/Al2= 4, the main phase was probably (MgOH4) (H2O)h[Al2(OH)
