| Abstract: | LiNbO_3 powders were prepared by sol-gel process using lithium tert-butoxide LiOC(CH_3)_3 as lithium source in place of lithium ethoxide LiOEt which is extremely moisture sensitive. The IR spectra and XRD patterns indicated that LiNbO_3 crystal was basically formed at 500℃ and completely crystallized at 700℃. |
