| Abstract: | By using an improved ceramic sintering technique, the sintering process for the preparation of large-size thin LiNbO3 ceramic targets for r. f. magneto-sputtering is studied. The problem of the deviation of chemical composition due to the loss of Li2O during sintering and of how to obtain LiNbO3 ceramic of high density has been sooved. The role of Li2O during sintering is discussed. A series of LiNbO3 Li2O ceramic targets of high density for sputtering have been prepared. |
