ferberite huebnerite wolframite FeWO4 - MnWO4 series XRD variation of cell parameters
FeWO_4 (ferberite) and MnWO_4 (huebnerite) series minerals have a continuous solid solution. The solid solution (wolframite) were synthesized by dry method at 800℃ in Nitrogen gas. The synthetic wolframites are aggregate of prismatic crystal and their colors are varying with the composition of their Fe contents from yellow to reddish brown. X-ray powder diffraction (Table 1) data for synthetic wolframite are examined by Guinier method and unit cell parameters (Table 2) obtained by a least squares calculation. These values (Figure 1) increased linearly with increasing Mn contents (Figure 1). The results similar to those of previous studies but have more linearity.
