Abstract: By using the average bond-gap model, chemical bond properities of LiNbO3 were studied. Calculated results showed that covalency of Nb-O bond was 0.2, and of Li-O bond 0.42. Racah parameter of Cr3+ ion and Mossbauer isomer shifts of Fe2+ ion in LiNbO3 were calculated by using the chemical surrounding factor, h, definited by covalency and electronic polarizability,and the results agreed with the experimental values.
Key words: LiNbO3, chemical bond, racah parameters, mossbauer isomer shifts
