Pychnometrically measured densities for the niobium oxide - bismuth oxide solid solution.

Lattice parameters determined by x-ray diffraction:

composition, lattice paramter, in angstroms
x = 0.1, a = 5.5314(19)
x = 0.15, a = 5.5033(3)
x = 0.2, a = 5.4847(5)
x = 0.225, a = 5.4736(4)


A summary of the results, comparing the observed (pychnometric) densities with the densities computed from the X-ray lattice parameter and the hypothetical reactions
