摘要

考虑了Ca/sub - 3/Ga/sub - 2/Ge/sub - 4/O/sub - 14/型结构中离子的同构性,并制定了寻找四组分氧化物体系新组分的标准。报道了两组新的无序四组分组合物的制备。Ln/sub - 3/Ga/sub - 3/Ge/sub - 2/BeO/sub - 14/具有较宽的均匀性。在二维四面体位上Be/sup 2+/的取代使Ln:Ga比值从3:5变为1:1,降低了石榴石的结构稳定性。这使得引入更小的,然后Nd/sup 3+/,稀土离子Sm/sup 3+/和Eu/sup 3+/。硅酸盐体系AO-BO/sub - 2/-M/sub - 2/O/sub - 3/B/sub -x/ M/sub - 2/Si/sub - 4-x/O/sub - 14/二元段存在四组分固溶体(A=Ca, Sr, Ba;B=Ge, Ti, Sn, Zr;M = Ga、铁)。一些ti - ga -硅酸盐成分看起来很有希望在熔融晶体中生长。讨论了四组分体系的结晶原理。

Two new lines of langasite family compositions
Isomorphism of ions in Ca/sub 3/Ga/sub 2/Ge/sub 4/O/sub 14/-type structure is considered and criteria of search for new compositions in four-component oxide systems are formulated. The preparation of two new groups of disordered four-component compositions is reported. Ln/sub 3/Ga/sub 3/Ge/sub 2/BeO/sub 14/, possessing wide range of homogeneity, exist with Ln = La-Eu. Substitution for Be/sup 2+/ in 2d tetrahedral site shifts Ln:Ga ratio from garnet one 3:5 to 1:1 and decreases garnet structure stability. This enables to introduce smaller, then Nd/sup 3+/, rare earth ions Sm/sup 3+/ and Eu/sup 3+/. Four-component solid solutions are found in binary section A/sub 3/B/sub x/M/sub 2/Si/sub 4-x/O/sub 14/ of silicate systems AO-BO/sub 2/-M/sub 2/O/sub 3/-SiO/sub 2/ (A=Ca, Sr, Ba; B=Ge, Ti, Sn, Zr; M=Ga, Fe). Some Ti-Ga-silicate compositions look promising for melt crystal growth. Principles of crystallization in four-component system are discussed.
