  Evidence of coexistence of Co3+ with Co2+ in ceramic Co3TeO6 through XANES,
DC magnetization and first principal studies is provided. XANES along with
linear combination fit provide relative concentrations of Co2+ and
Co3+.Temperature dependent DC magnetization exhibits the same antiferromagnetic
behavior as observed in single crystal. The presence of both Co2+ and Co3+
suggests that if the later is in high spin state, the effective magnetic moment
is similar to that observed in single crystal studies. In contrast, if Co3+ is
in low spin state effective magnetic moment is similar to that observed in
Co3O4. It is further shown that both Co2+ and Co3+ in high spin states
constitute a favorable ground state through first principle calculations where
Rietveld refined Synchrotron X-ray diffraction data are inputs.
