Study on the production of the columbite phase (Mg Nb2 O6) by using the polymeric precursor method
- 1. Sao Carlos Univ., SP (Brazil). Dept. de Quimica
Description
Columbite powders (Mg Nb2 O6) were synthesized by polymeric precursor method, or Pechini. Studies of thermogravimetric and differential thermo analysis, infrared spectroscopy, nitrogen adsorption/desorption isotherms and X-ray diffraction showed high reactive and crystalline powders. High surface area about 48 m2 g-1 was obtained and no Mg O or Nb2 O5 was observed. (author)
