Gel growth and characterization of bismuth oxalate single crystals

The simultaneous growth of Bi 2( C 2 O 4) 3·7 H 2 O and Bi 2( C 2 O 4) 3· H 2 C 2 O 4 single crystals, by two different techniques (slow evaporation from solution and gel growth) is reported. The work includes a comprehensive characterization for both compounds, performed on the much better gel grow...

Description
Summary:The simultaneous growth of Bi 2( C 2 O 4) 3·7 H 2 O and Bi 2( C 2 O 4) 3· H 2 C 2 O 4 single crystals, by two different techniques (slow evaporation from solution and gel growth) is reported. The work includes a comprehensive characterization for both compounds, performed on the much better gel grown specimens, as well as single crystal and powder X-ray data and a thorough study of the thermal behaviour. Dominant hillocks giving rise to vicinal faces in Bi 2( C 2 O 4) 3· H 2 C 2 O 4 are described, and a tentative explanation for their existence is given.
