About MetamuniriteHide

Formula:
NaVO3
Colour:
Colourless
Specific Gravity:
2.877

Orthorhombic
Name:
Named for its probable relationship to munirite.
May form by dehydration of munirite.


Classification of MetamuniriteHide

Density:
2.877 g/cm3 (Measured)    2.926 g/cm3 (Calculated)

Measured is synthetic material

Optical Data of MetamuniriteHide

Type:
Biaxial (+)
RI values:
nα = 1.780(2) nβ = 1.800(2) nγ = 1.850
2V:
Measured: 30° to 40°
Birefringence:
Note that the calculated and illustrated birefringence is a minimum, based on nγ = 1.85; because nγ is reportedly >> 1.85, the actual observed birefringence will be higher.
Max Birefringence:
δ = 0.070
Image shows birefringence interference colour range (at 30µm thickness)
and does not take into account mineral colouration.
Surface Relief:
Very High
Dispersion:
r > v distinct
Optical Extinction:
X = c; Y = a; Z = b; positive elongation

Chemical Properties of MetamuniriteHide

Formula:
NaVO3
IMA Formula:
NaV5+O3

Crystallography of MetamuniriteHide

Crystal System:
Orthorhombic
Cell Parameters:
a = 14.13 Å, b = 3.64 Å, c = 5.35 Å
Ratio:
a:b:c = 3.882 : 1 : 1.47
Unit Cell V:
275.17 ų (Calculated from Unit Cell)
Morphology:
Needle-like crystals, which sometimes are broadened into narrow laths. Dominant crystal habit is {101}, with no clearly developed terminal faces.
