Abstract
The invention relates to highly reactive metal niobate and/or tantalates of the general formula (Me(II)A<-2 O<-6 and/or Me(III)AO<-4 , where A = Nb and/or TA and Me = Mg, Fe, Co, Ni, Cr, Mn, Cd and/or Zn, process for its production, its further processing to obtain perovskites of the general formula A(B'B'')O<-3, where A = Pb and/or Ba, B' = Mg, Fe, Co, Ni, Cr, Mn, Cd, Ti, Zr and/or Zn und B'' = Nb and/or Ta, and said perovskites.
